Great video! Followed every step and got my BLtouch to finally work. Especially loved that it focused on the SKR board. Many other youtube videos cover the generic V4.2.2 board that comes with the Ender 3.
Great video! One little tip for ya...instead of having to add G29 to your gcodes, you could always uncomment ENABLE_LEVELING_AFTER_G28. This way it's always going to use your ABL mesh. I personally like to hard code all my standard settings (including my calibrated esteps number) that way I don't have to mess with it later. Another fun thing to add so you don't have to manually mess with it later is changing the preheating presets. (line 1702). I don't print ABS, so I replaced it with PETG and set my standard nozzle and bed temps for each.
A Great tip Andrew! I will be installing an SKR Mini E3 V2.0 as soon as it is delivered as I recently went through the pain of installing a BL Touch Kit from Creality with 1.1.6 BL Touch firmware and it is terrible firmware, the x,y offsets were not changed so when probing the nozzle was in the position where the probe should have been, and also when slicing a part in the centre of the bed it ends up printing far right on the bed, also they did not implement baby-stepping so you had to restart a calibration print for each change of the z offset which decided to stop working altogether after a while, and I am not 100% convinced the firmware is actually using the mesh created by the BL Touch, Creality did not answer any of my questions and I contacted them in 8 different ways, I bought the kit thinking it would save me time from editing firmware, I think I have learned the hard way about Creality's programming skills, which isn't really programming but the config editing and they cant get that right for their own printer!
Holy crap man!!!! I have looked everywhere for a video that explains and showed exactly what you did!!! Thank you so much!! I have had the bl touch for 6 months, hooked up for 3 and never plugged it in because I had no idea what I was doing. I have watched hours of RUclips trying to figure it out and googling everything and couldn’t find anything that explained it better. No one explained the wires switched, and mine were and I was so confused. I’m new at printing so I got the already done one you showed, I just picked one and hoped it was right, but your video confirmed it was the right one. Thank you so much.
Hi. Thanks for the feedback and the lack of content around alot of 3d printing is one of the reasons i started this channel. Im glad you were able to get everything running.
This video saved my Ender! I've been convinced for the last year that ABL is worthless and the BLTouch is junk. Turns out my firmware just wasn't using the mesh, or something, and was severely outdated. I didn't have the probe wizard, or babystepping that could save into the offset on the fly, or a ton of other quality of life improvements. Now my first layer is going down perfectly even and the interface is easier than ever to use. Thank you so much!
I tried 5 different firmwares to get the BL touch to work on the BTT E3 V2, none worked. Most other compiling videos make assumptions on computer knowledge, which resulted in failed results. This video was to the point and not a watch builder video.(Definition: "Watch builder" You ask someone what time it is and they tell you how to build a watch). Thank You!
I'm considering a BTT board upgrade for my new Ender 3 Pro, and just wanted to say thank you very much for covering the layout and firmware modification for a 5-pin probe setup versus the 3-pin and 2-pin split setup, even though you were using the latter. Can't wait to silence these motors!
Thanks a lot for this video! I was having issues with my BTT SKR MINI E3 V3.0 and Creality CR-Touch on my Ender 3 but your video was very helpful, and my printer runs flawlessly now.

@@3DPrintscape I installed a real touch that had all five wires in one ribbon. I was installing it into an SKR mini v2. I had planned on using the street five pen but all of the wires were in the wrong color order. What I ended up doing was stealing the JTL connector off of my Stock Z stop, Took the black and white wires out of the street five wire ribbon. Then I rewired the blue yellow and red to match the description in your video. Then I had to re-wire the five wires coming out of the BL Touch unit itself. I had it all working out with someone else’s firmware video and then I decided to make extra changes that you had in your firmware video and now it is not working. I’m not sure what changes were made that made the system not work any longer.
@@markpicklesimer75Try to comment out #define BLTOUCH_DELAY 500 and #define BLTOUCH_FORCE_SW_MODE in the configuration_adv.h file. I know these setting have cause problems with some of the bltouch clones/off-brands.
I was with you up until ~5:30. Not sure how you got from installing the hardware to measuring the distance the probe is from the bed. I'm assuming you powered on and went it went to the home position? What firmware do you have installed at this point and how did you do that? I think I have the wrong firmware installed because mine isn't moving when powered on.
Hi. Once the hardware is installed, you need to flash the firmware then set the z offset, i think your on the last part right now. Im using a custom build of marlin, but the process is the same with the creality firmware. Do you see bltouch or anything in the printer menus?
well its a good thing I watched this before just plugging my signal wires in, I had the blue and red swapped like you said so you saved me some smoking cables!
I've been having issues with setting up the firmware. for some reason every #define line is an error. i saw that was the case in the video to, but then they just dissapeared at 11:47. I tried following the axact steps, including commenting the s stop out and back in, but nothing changed like it does in the video. these errors also mean i can't compile the firmware.
Thank you for putting this video together. It is very appreciated. It would be immensely helpful if you could: 1) improve the screen capture quality -- on my hi-res screen It is blurry and near impossible to distinguish the text. 2) could you speak out the name of the parameter you are modifying rather than using terms like "uncomment this". Again thank you for the effort you put into this video and for sharing your knowledge.
Hi. Thanks for the feedback, i will work on those going forward. The screen capture resolution has been tricky due to different sizes. I ended up settling on 1080p captures for now.
Great guide, extremely helpful but once I click build it says - Unknown environment names 'STM32F103RC_btt_512K'. I'm using a CR-Touch but should follow the same steps right? Help will be much appreciated
@@3DPrintscape Thanks, ended up trying that and successfully compiled the firmware but now it says 'no printer attached', any idea what the problem could be?

Hi. It sounds like the firmware folder may need to be moved closer to the root of the drive you are working on. The folder structure of the firmware goes pretty deep and Windows doesnt like long paths/file names. I typically create a folder called firmware right off my c drive and put the firmware there.
Can you plz help me im trying to do this on my anycubic mega zero with the stock board would there be a way that you can get all the firmware ready and like share the done file so all I do is put it on my SD card ove been working on it for about 10 hours and its not working

I'm having issues with the bltouch probing off the bed on the y-axis during bed leveling. The initial probe (homing probe) is perfectly in the middle. The second probe (front left) then tracks to miss the bed. I also have my offsets set correctly (given offsets for my Hero me 5). So far to get printing i've had to change the probe offset for the y-axis to be technically incorrect. The home probe is not centered, but the rest work...Any ideas?
Hi. First make sure you cleared your eeprom. If thats done and you are still having the issue you can adjust your #define X_MIN_POS & #define Y_MIN_POS values. I think im running -5 and -10 as i had a similar issue.
Hi. I havent grabbed the latest build in a while so im not sure if the recent changes from the bug fix line were merged to it. If they were not, you will need to add the _512k, if they were you will get an error if you add it and try to compile.
I can’t seem to find the babystepping feature. I was able to compile it fine at first, but had to recompile another .bin file for the offsets when my printer autohomes. Any tips? I’ve got what you toggled and even enabled the feature where it’s always available. No dice still.
Hi. Try to clear eeprom if you haven’t already. If you have maybe check in the menus for something that sounds similar in function, maybe they moved it.
Had an issue with my bl touch inconsistently deploying. Seems to have been fixed by re-terminating the red-blue-yellow cable with the proper connector. The longer connector is meant for different sized pins and was sitting very loosely on the onboard connection.
First of all, thanks for the video. I did exactly what you did, however when I press Auto Home the z axis collides with the table. I'm using the connection as shown. To rule out that it wasn't wiring, I used the BIGTREETECH firmware and it worked perfectly, however it doesn't allow negative z_offset and I would like to use my own firmware like you. Do you know what I could have done to prevent the z axis from stopping with the BL touch?
This is more of a Viscose issue, I don't have that "check mark" on the bottom. I've been struggling for about 4 days now to set this stuff up. Please help.
Hi. It sounds like Platform.io wasnt installed, VS Code wasnt restarted after the install, or the wrong firmware folder was opened. The folder should be the top level folder and have the platformio.ini file in it.
If you have the C++ and Platformio IDE extensions installed, check to make sure you have opened up the folder which contains the 'platformio.ini' file. The check mark won't show up unless this file is at the top of the folder file structure. You might not have the correct folder open because Windows "Extract All" will add another folder layer during the extraction process.
@@lynnkeith2289 Im glad to hear its fixed. platformio installs C++, but if something happened to that install I could see it causing the behavior you saw.
Hi Robert, Thanks for all the great how-to videos. When I initially added the ABL gcode (G29 ; ABL) to the Cura profile for the Ender 3 Pro, everything functioned properly from OctoPrint until I adjusted the bed a week later. The Z Offset and ABL calibrations from this video was executed countless times with no success. After hours of playing with these settings, I notice the calibration functioned properly through the printer display screen but failed via OctoPrint. I removed the G29 code from the Cura profile and it is now working from OctoPrint. I don't believe the G29 code execution itself from OctoPrint is the issue. Is the G29 pulling stored parameter values from OctoPrint or the controller to calculate the new ABL parameters? My printer has the BTT SKR MINI E3 V3.0 Controller and TFT35-E3-V3.0.1-Touch-Screen-Display.. Is there any other area I need to be looking at?
Hi. Thats interesting, it has to be tied to how octoprint handles things. It bypasses a lot and wants things it own way. The g29 command runs the mesh and stores the peramitors. You need to save settings for them to persist through a power cycle. What happens if you just send the g29 command manually from octoprint?
When I follow your instructions on VS Code I don't have checkbox to build on my (latest) version there are 2 errors in the far bottom left though, any thoughts on this? The 2 errors are to update include path
I fixed this, I had been in the Python environment prior to configuring this firmware and it loaded up the next time in python, I just switched to Platformio
Hi. Im glad you got it working, though the python environment shouldnt be needed. I don't have that running now and it works for me. My guess is that it installed/repaired another component.
@@3DPrintscape I was using python for something else prior to configuring the firmware and VS Code must have loaded in Python mode when I came to configuring Marlin, that's why I was getting errors and no checkbox
The Failed to enable bed leveling error can be resolved by starting a bed leveling mesh after doing you z offset. This was a great video thank you for all the help.
Robert this video is great I have 2 ender 3 pro'2 and 1 has this exact board in it so this video helped me get my bl touch installed perfectly. I am running the factory firmware on it but would love to build a version like you did in the video. I wish I could get a copy of the one you built on here, as my printer is the exact same. I am just not quite comfortable enough to write my own firmware yet LOL. I was able to obtain a full version of marlin for my other printer which has the stock 4.2.2 board and it runs so much better than the creality firmware. Just wanted to say again great video it helped me very much.
Very informative and has helped, but I have an issue I haven't been able to resolve. I'm running the SKR mini e3 on a CR10S5 so had to also adjust bed size, but otherwise used your settings on BTT firmware for 1.2 using the probe/servo pins on a 3dtouch. When trying to level, the z doesn't stop when the probe shows it's triggered, which of course leads to an error of hitting the endstop. I have adjusted my z offset....is there another setting I need to look for? I would think from other videos once triggered the z should stop even if in the air? The LED does show it's triggered, but keeps going.
Hi. Thanks for the feedback. How is the bltouch wired? It sounds like you have it wired with all five pins going to the bltouch port but the firmware configured for z homing with the bltouch.
My BL Touch has the wiring harness with BLUE, RED,, YELLOW, BLACK, WHITE. Can I place this where the "BL Touch" goes according to your first selection/option goes? My BLUE wire is on the outside (first wire) then the RED and so on. Also, according to your video, where your BLUE, RED, and YELLOW wires are, would the next wires be BLACK then WHITE, or WHITE then BLACK?
Hi. The short answer is it depends. The problem is i have seen these shipped with too many different wiring colors. I would recommend mapping the color back to the pin and making sure its plugged into the right spot on the board.
i have tried to add the fireware.bin to my sd card and put it into the tft slot. The firmware doesn't load. Any advice? The firmware.bin file is in the root and i did manage to upgrade the tft firmware following your video tutorial. no sure what to do here now
I attached bl touch like u did in video and download firmware bltouch z homing. Now z motor only can go up. Same thing if i try trough menu manualy lowering z axis.
I’m a bit confused, if my wires came with the 5 pin, do I still need to change it for the 3 pin adapter? Also, with the 5 pin connector, do I still need to change wires around to prevent any possible problems?
Hi. No, use the 5 pin adapter and plug it into the bltouch port and leave the z-stop plugged in. Also, make sure the wiring is in the right order on the 5 pin adapter.
Hi, I wired my BL touch the way you showed, and downloaded the firmware but my printer won't move down. It responds to everything but Z down so the autohome also doesn't work. Any suggestions?
Hi. The checkmark not being there is typically caused by the platformio/c++ plugin not being installed (or the install was bad) or the wrong folder is opened in workspace.
I followed your video step for step. Once you made a change vsCODE I paused the video and made SAME changes. Ok. Mine compiled just fine. I got my ender 3 pro with Mini e3 v3. Well almost. The blTouch levels the center of the bed but when it’s starting a print and lays down that warmup line on left side of bed, we’ll the hot end is still 1/2” off the bed. The abl pin does not extend. And the assembly does not lower to print. I thought at first it was the gcode of the file I tried. So I tried a different gcode and same thing happened. Is there a firmware setting I could look at for this ??
Noticed your comments about the ABL Mesh error after updating the TFT firmware. However, when I do the mesh leveling it only appears to attempt to do it at the bottom front left and doesn't move across the board. to the other points, as I would expect. What am I doing wrong?
@@3DPrintscape I will check, also need to make sure I have installed it correctly. Progress :-) 1. Installed the BL touch unit and wired it so that the original Z-switch stays in place 2. Installed the required firmware for using the BLT touch from the Bigtreetech Github 4. Restarted the Printer 5. Ran the ABL bed leveling which seem to work this time. Although I have a Y-Axis belt tightner adaptor, which confused things when the bed went to take the top measurement, the bed moved too far forward and grumbled (there must be a setting I can change to change the travel distance, if so please advise) , it was ok after that point and I saved the settings. The only thing I could not do was set the P-Offset (I think it's shown as Z-offset on your video). I know if I used the firmware which does not require the original z-end stop switch, the function worked to a point. If I use it as it now, it homes the printer. Raises the head 10mm and then should go to the center of the bed, but on mine, it tries to move the head to the left while its in the home position. and I have to turn the printer off as the motor/belt for X-Axis start making a hell of a noise. Any ideas why?
@@3DPrintscape All I installed was the "firmware-bltouch.bin" file, should I have installed the file "firmware.bin" to replace the factory stock firmware first? and then apply the "firmware-bltouch.bin" after or is the "firmware-bltouch.bin" the newest firmware for the board including the BLtouch function. The notes on the bigtreetech github seem to imply the firmware.bin file for the ender 3 does not support BLT, hence why I used the firmware-bltouch.bin" file. Sorry for all the questions UPDATE : I think I know why - I left the original Z-endstop switch connected to the board, so I'm guessing this will confuse the printer and it's going to assume that the home position for the z-offset is now at the bottom left of the board and not the centre of the board, Correct? Should have paid closer attention to you video if this is the case :-)
@@abtrooper82 The firmware should have been named firmware.bin, I don't think the skr will pick up the firmware if its named something else. Also, the z stop should still be connected in most cases.
Hello, thank you for making this video, it was very helpful. I’m stuck one a problem though. I was able to compile and flash my firmware onto my printer, but now when I go to auto home, the auto homing sequence doesn’t even touch the X or Y endstops (which would lead to some collisions later on if I tried to do anything else with the printer). But The Z sequence works with the BLTouch probe just fine. I flashed firmware from bigtreeTech to confirm it wasn’t a wiring issue, and the auto homing worked perfectly fine for X and Y with the bigtree firmware. However there were some problems with the Z home sequence that are more troublesome than they are worth. Anyways I’m assuming this is now just a coding issue. So now I’m trying to make my compiled firmware work. Do you have any suggestions to fix the x and y homing issue? Thanks.
I ended up restarting with the same btt code. I followed a step by step guide online for Ender v1s and it ended up working. Not sure what the issue was as I was watching several different videos (probably the root problem) on how to code the firmware, but it was definitely a coding/user issue
Is there an easy way to avoid the bed moving too far forward when leveling the bed. I have a tension belt adaptor for the Y-Axis which upsets the bed when measuring as it comes too far forward.
Hello, i can`t get the bltouch to run. Homing the z-axis doesn´t work-> stopped. With M119 i get the message z min: triggerd, shouldn`t it open? How can I fix this problem? Z_MIN_ENDSTOP_INVERTING false, changing to true doesn´t work, because marlin can´t compile it. Thanks
Hi. My initial thought is that the sensor wires are reversed or the config doenst match how the bltocuh is wired. Z_MIN_ENDSTOP_INVERTING should be false if you are running a build from after June 2021.
I have a issue, the probes are working fine but when you start to print it is as if the printer forgot the layout of the bed. the z axis wont move to adjust for the bed being uneven, any idea on how to fix this?

Such a great guide, but i feel like im being a dumdum and doing something wrong. Ive got the creality BLTouch, set it up in the way that has you using the 3 pins on the main port of the board (Swapping my pins in the connector around so they were blue/red/yellow, the blue/red were reversed initially), and then using the "z-stop" 2 pin location on the board. I got the firmware for the z-homing, put it on an SD card- Turn the printer on, it clicks the BL-Touch sensor a few times, then bonks at me about not being able to enable bed leveling / invalid mesh.

My printer ignores both ZSTOP and BLTOUCH, I've done everything exactly like you but with the 5 pin configuration(the ZSTOP is still connected but not in use by the firmware). When I try to home it ignores both stops, it doesnt work properly if I use the bin from bigtreetech but they only do a single probing which is why I wish I could use the custom firmware.
Hi. If it works with the BTT firmware, the wiring is good so it sounds like there is an issue with the firmware. Im guessing it doesnt match how its wired. Make sure you comment out #define Z_MIN_PROBE_USES_Z_MIN_ENDSTOP_PIN and uncomment #define USE_PROBE_FOR_Z_HOMING in the firmware.

Shouldn't the Z offset be done with a pre-heated bed and nozzle? There is expansion of each after reaching temp and this will affect the gap, not insignificantly.
Hi. I tend to make the final adjustments with babystepping, which is done when everything is up to temp, but to answer your question. Yes, you should have the nozzle and bed heated up.
There's no check at the bottom left of my hot bar only 2 icons and it says no problems. The only thing I havnt done is the probe to nozzle distances because I don't have my hotend mounted currently
Hi. There are a coupel of things that would cause the checkmark not to be there 1) you dont have the right folder open 2) platformio is not installed 3) plaformio failed to install the C/C++ plugin.. Can you check all that?
@@3DPrintscape Vscode says the terminal process failed to launch path to shell executable and then says my file doesn't exist. Platformio installed. Aswell as c/c++
Just tried installing the SKR E3 V3 board, But the hot end (E0) will not heat. This i the second board with the same error. I there anything that I could have done to cause this. Great Video
Hi. You should verify the pin out for your bltouch, ive seen them shipped with different wiring colors. If yoou need to swap the pin, there is a little tab you can pull on the adapter that will allow you to pull the wire out.
@@3DPrintscape hey one more question. so if i still have the stock fan cover i can just take either the SKR firmware or the Marlin firmware, download it, change name to firmware.bin, pop it on an SD, put it in my printer and then I'm good? or do i have to make changes in the firmware still?
i downloaded the SKR Mini Firmware and when i turn it on and hit bed leveling it just says home z first. i downloaded the frimware where you attach the BLTouch to the Z stop
Hello, amazing video but I have two questions 1. I keep getting this error message that does not let compile the files. Do they work if I just save them in notepad? 2. I can not seem to locate that .pio file even after i enabled to view hidden files. please help me.
Hi. I would need the actual error message to help with number 1 and what are you trying to save to notepad? For number 2 the folder gets created when the first build starts, even if it fails. The only exception would be if the account doesnt have permissions to create the folder, which would also cause the build to fail.
Just decided to tackle this tonight with the “stock,” firmware for bltouch ztop . The bracket I printed for it had the probe too high, so I used the springs to space it…either way, when I go to auto home Z it just goes super high, and then throws “z end stop,” error and the I lose all ability to move Z down until I reset the machine. Any ideas?
@@3DPrintscape Exactly as you showed. I was using the precompiled firmware. Seems as if a lot of people in the reddit were having similar issues with that firmware. I'm currently trying with the config you set up here. However, I did notice that putting in the "_512k" line caused failures when compiling.
@@3DPrintscape By the way, I wrote the file as you directed and it worked, I'll share this with the reddit page, in case anyone else has the issue with the precompiled firmware
Thanks for taking the time to teach this to us noobs lol however i have the exact same setup and followed all the instructions and the z offset icon does not populate on my tft35 E3 v3 in touch mode when going to the ABL section. its showing that its available in marlin mode though. any suggestions?
Hi! Can you please help me. My bed keeps hitting the nozzle on autobed leveling!! I have ender 5 with skr mini v1.2 and bltouch. I can't find any relevant tutorials for this exact problem 😭 thank you!!
Hi. It sounds like it could be a firmware or wiring issue. Can you join me on discord, it will be easier to help with troubleshooting there. discord.gg/Bu94EYVkrU
At the end of my firmware build, I received this message..."There are the new updates for platforms (ststm32) Please update them via `platformio platform update` command." Should I update and do the process over again?
Great Video! So, I followed these instructions, and everything checked out but when I tried to build the code I got an error "The terminal process "C:\Users\brayd\.platformio\penv\Scripts\platformio.exe 'run'" terminated with exit code: 1." And at the top of both the configuration.h and configuration.adv.h. There was a red squiggly line under “* Marlin 3D Printer Firmware” on the first line of both configurations. That was the only error present. Any ideas on what to try?
It's a great guide! So helpful! Thanks for posting it. After I have tried everything, there's still one thing that I can't fix, the bltouch only measures the bottom left corner for bed leveling and I can't get it to measure more points on the bed. What can I do? Thank you in advance!
Hi. Is it actually probing the bottom left corner or attempting to and failing? If it cant get a good read, it will just fail then move onto the print.
Hey, do you know why wherever from I download a marlin, I dont have .pio folder ? I dont know what to do. If this helps i have windows 11 and i see other dot files like .github Please help :(

You're Welcome!
Great video! Followed every step and got my BLtouch to finally work. Especially loved that it focused on the SKR board. Many other youtube videos cover the generic V4.2.2 board that comes with the Ender 3.
Hi. Thanks for the feedback and im glad you got the bltouch working.
Hey thanks! Tried for a long time, your firmware edits made it work. Thaaaank youuuuuuu!
Glad I could help :).
You saved my printer. Was about to launch it off a bridge. Followed you tutorial carefully and now I'm printing with great results. Thank you
Glad I could help :)
Great video! One little tip for ya...instead of having to add G29 to your gcodes, you could always uncomment ENABLE_LEVELING_AFTER_G28. This way it's always going to use your ABL mesh. I personally like to hard code all my standard settings (including my calibrated esteps number) that way I don't have to mess with it later. Another fun thing to add so you don't have to manually mess with it later is changing the preheating presets. (line 1702). I don't print ABS, so I replaced it with PETG and set my standard nozzle and bed temps for each.
Hi. Thanks for the feedback and tips. I didn’t think of changing that in the firmware but ya it would work.
A Great tip Andrew! I will be installing an SKR Mini E3 V2.0 as soon as it is delivered as I recently went through the pain of installing a BL Touch Kit from Creality with 1.1.6 BL Touch firmware and it is terrible firmware, the x,y offsets were not changed so when probing the nozzle was in the position where the probe should have been, and also when slicing a part in the centre of the bed it ends up printing far right on the bed, also they did not implement baby-stepping so you had to restart a calibration print for each change of the z offset which decided to stop working altogether after a while, and I am not 100% convinced the firmware is actually using the mesh created by the BL Touch, Creality did not answer any of my questions and I contacted them in 8 different ways, I bought the kit thinking it would save me time from editing firmware, I think I have learned the hard way about Creality's programming skills, which isn't really programming but the config editing and they cant get that right for their own printer!
Thank You Thank You Thank You I had spent days trying to get it to run. With your video it was running in 2 hrs

Holy crap man!!!! I have looked everywhere for a video that explains and showed exactly what you did!!! Thank you so much!! I have had the bl touch for 6 months, hooked up for 3 and never plugged it in because I had no idea what I was doing. I have watched hours of RUclips trying to figure it out and googling everything and couldn’t find anything that explained it better. No one explained the wires switched, and mine were and I was so confused. I’m new at printing so I got the already done one you showed, I just picked one and hoped it was right, but your video confirmed it was the right one. Thank you so much.

This video saved my Ender! I've been convinced for the last year that ABL is worthless and the BLTouch is junk. Turns out my firmware just wasn't using the mesh, or something, and was severely outdated. I didn't have the probe wizard, or babystepping that could save into the offset on the fly, or a ton of other quality of life improvements. Now my first layer is going down perfectly even and the interface is easier than ever to use. Thank you so much!
You're welcome, im glad i could help :).
I tried 5 different firmwares to get the BL touch to work on the BTT E3 V2, none worked. Most other compiling videos make assumptions on computer knowledge, which resulted in failed results.

It turns out that I have V2 instructions but my BL Touch is a V3.1. I still need help
@@markpicklesimer75 Hi. I can try to help out. What issues are you having?
@@3DPrintscape I installed a real touch that had all five wires in one ribbon. I was installing it into an SKR mini v2. I had planned on using the street five pen but all of the wires were in the wrong color order. What I ended up doing was stealing the JTL connector off of my Stock Z stop, Took the black and white wires out of the street five wire ribbon. Then I rewired the blue yellow and red to match the description in your video. Then I had to re-wire the five wires coming out of the BL Touch unit itself. I had it all working out with someone else’s firmware video and then I decided to make extra changes that you had in your firmware video and now it is not working. I’m not sure what changes were made that made the system not work any longer.

DUDE! You saved my ass with wiring... had red and blue reversed!!! Thanks!
Hi. Cool, glad you got it working.
I was with you up until ~5:30. Not sure how you got from installing the hardware to measuring the distance the probe is from the bed. I'm assuming you powered on and went it went to the home position? What firmware do you have installed at this point and how did you do that? I think I have the wrong firmware installed because mine isn't moving when powered on.
Hi. Once the hardware is installed, you need to flash the firmware then set the z offset, i think your on the last part right now. Im using a custom build of marlin, but the process is the same with the creality firmware. Do you see bltouch or anything in the printer menus?
well its a good thing I watched this before just plugging my signal wires in, I had the blue and red swapped like you said so you saved me some smoking cables!

Thank you for putting this video together. It is very appreciated. It would be immensely helpful if you could: 1) improve the screen capture quality -- on my hi-res screen It is blurry and near impossible to distinguish the text. 2) could you speak out the name of the parameter you are modifying rather than using terms like "uncomment this". Again thank you for the effort you put into this video and for sharing your knowledge.

Hi. It sounds like the firmware folder may need to be moved closer to the root of the drive you are working on.

I'm having issues with the bltouch probing off the bed on the y-axis during bed leveling. The initial probe (homing probe) is perfectly in the middle. The second probe (front left) then tracks to miss the bed. I also have my offsets set correctly (given offsets for my Hero me 5). So far to get printing i've had to change the probe offset for the y-axis to be technically incorrect. The home probe is not centered, but the rest work...Any ideas?
Hi. First make sure you cleared your eeprom. If thats done and you are still having the issue you can adjust your #define X_MIN_POS & #define Y_MIN_POS values. I think im running -5 and -10 as i had a similar issue.
So I downloaded the BigTree Firmware and its STM32F103RC_btt_maple, do i still need to change it to 512K
Hi. I havent grabbed the latest build in a while so im not sure if the recent changes from the bug fix line were merged to it. If they were not, you will need to add the _512k, if they were you will get an error if you add it and try to compile.
Thank you for this, i have this exact setup on the way soon .
Glad I could help
I can’t seem to find the babystepping feature. I was able to compile it fine at first, but had to recompile another .bin file for the offsets when my printer autohomes. Any tips? I’ve got what you toggled and even enabled the feature where it’s always available. No dice still.
Hi. Try to clear eeprom if you haven’t already. If you have maybe check in the menus for something that sounds similar in function, maybe they moved it.
This was very helpful. Thank you!
You're Welcome!
Had an issue with my bl touch inconsistently deploying. Seems to have been fixed by re-terminating the red-blue-yellow cable with the proper connector. The longer connector is meant for different sized pins and was sitting very loosely on the onboard connection.
Hi. Thats an interesting one, thanks for sharing.
Much appreciated
Hi. Thanks for the feedback :)
First of all, thanks for the video. I did exactly what you did, however when I press Auto Home the z axis collides with the table. I'm using the connection as shown. To rule out that it wasn't wiring, I used the BIGTREETECH firmware and it worked perfectly, however it doesn't allow negative z_offset and I would like to use my own firmware like you. Do you know what I could have done to prevent the z axis from stopping with the BL touch?
Hi. It sounds like a wiring/firmware mismatch. How is the bltouch wired and is the z stop connected?
This is more of a Viscose issue, I don't have that "check mark" on the bottom.
I've been struggling for about 4 days now to set this stuff up. Please help.
Hi. It sounds like Platform.io wasnt installed, VS Code wasnt restarted after the install, or the wrong firmware folder was opened. The folder should be the top level folder and have the platformio.ini file in it.
@@3DPrintscape You have to install C++ in VS. I had the same issue and that fixed it!
If you have the C++ and Platformio IDE extensions installed, check to make sure you have opened up the folder which contains the 'platformio.ini' file. The check mark won't show up unless this file is at the top of the folder file structure. You might not have the correct folder open because Windows "Extract All" will add another folder layer during the extraction process.
@@lynnkeith2289 Im glad to hear its fixed. platformio installs C++, but if something happened to that install I could see it causing the behavior you saw.
@@Christopher-nt6fg It definitely possible he had the wrong folder selected as well, but if C++ wasn't installed it would behave similarly.
Hi Robert, Thanks for all the great how-to videos. When I initially added the ABL gcode (G29 ; ABL) to the Cura profile for the Ender 3 Pro, everything functioned properly from OctoPrint until I adjusted the bed a week later. The Z Offset and ABL calibrations from this video was executed countless times with no success. After hours of playing with these settings, I notice the calibration functioned properly through the printer display screen but failed via OctoPrint. I removed the G29 code from the Cura profile and it is now working from OctoPrint. I don't believe the G29 code execution itself from OctoPrint is the issue. Is the G29 pulling stored parameter values from OctoPrint or the controller to calculate the new ABL parameters? My printer has the BTT SKR MINI E3 V3.0 Controller and TFT35-E3-V3.0.1-Touch-Screen-Display.. Is there any other area I need to be looking at?
Hi. Thats interesting, it has to be tied to how octoprint handles things. It bypasses a lot and wants things it own way. The g29 command runs the mesh and stores the peramitors. You need to save settings for them to persist through a power cycle. What happens if you just send the g29 command manually from octoprint?
When I follow your instructions on VS Code I don't have checkbox to build on my (latest) version there are 2 errors in the far bottom left though, any thoughts on this?
The 2 errors are to update include path
I fixed this, I had been in the Python environment prior to configuring this firmware and it loaded up the next time in python, I just switched to Platformio
Hi. Im glad you got it working, though the python environment shouldnt be needed. I don't have that running now and it works for me. My guess is that it installed/repaired another component.
@@3DPrintscape I was using python for something else prior to configuring the firmware and VS Code must have loaded in Python mode when I came to configuring Marlin, that's why I was getting errors and no checkbox
The Failed to enable bed leveling error can be resolved by starting a bed leveling mesh after doing you z offset.
This was a great video thank you for all the help.
Hi. Ya that’s how you get rid of that message and you’re welcome.
Robert this video is great I have 2 ender 3 pro'2 and 1 has this exact board in it so this video helped me get my bl touch installed perfectly. I am running the factory firmware on it but would love to build a version like you did in the video. I wish I could get a copy of the one you built on here, as my printer is the exact same. I am just not quite comfortable enough to write my own firmware yet LOL. I was able to obtain a full version of marlin for my other printer which has the stock 4.2.2 board and it runs so much better than the creality firmware. Just wanted to say again great video it helped me very much.
Hi. Thanks for the feedback. I actually have build available here that you can use. 3dprintscape.com/marlin-firmware-builds/
Very informative and has helped, but I have an issue I haven't been able to resolve. I'm running the SKR mini e3 on a CR10S5 so had to also adjust bed size, but otherwise used your settings on BTT firmware for 1.2 using the probe/servo pins on a 3dtouch. When trying to level, the z doesn't stop when the probe shows it's triggered, which of course leads to an error of hitting the endstop. I have adjusted my z offset....is there another setting I need to look for? I would think from other videos once triggered the z should stop even if in the air? The LED does show it's triggered, but keeps going.
Hi. Thanks for the feedback. How is the bltouch wired? It sounds like you have it wired with all five pins going to the bltouch port but the firmware configured for z homing with the bltouch.
My BL Touch has the wiring harness with BLUE, RED,, YELLOW, BLACK, WHITE. Can I place this where the "BL Touch" goes according to your first selection/option goes? My BLUE wire is on the outside (first wire) then the RED and so on. Also, according to your video, where your BLUE, RED, and YELLOW wires are, would the next wires be BLACK then WHITE, or WHITE then BLACK?
Hi. The short answer is it depends. The problem is i have seen these shipped with too many different wiring colors. I would recommend mapping the color back to the pin and making sure its plugged into the right spot on the board.
i have tried to add the fireware.bin to my sd card and put it into the tft slot. The firmware doesn't load. Any advice? The firmware.bin file is in the root and i did manage to upgrade the tft firmware following your video tutorial. no sure what to do here now
Hi. Make sure the SD card is 8GB or less and formatted as FAT32.
I attached bl touch like u did in video and download firmware bltouch z homing. Now z motor only can go up. Same thing if i try trough menu manualy lowering z axis.
Hi. Sounds like the wiring is wrong or the firmware doesn't match the wiring. How is it wired and what firmware are you using?
I’m a bit confused, if my wires came with the 5 pin, do I still need to change it for the 3 pin adapter? Also, with the 5 pin connector, do I still need to change wires around to prevent any possible problems?
Hi. No, use the 5 pin adapter and plug it into the bltouch port and leave the z-stop plugged in. Also, make sure the wiring is in the right order on the 5 pin adapter.
Hi, I wired my BL touch the way you showed, and downloaded the firmware but my printer won't move down. It responds to everything but Z down so the autohome also doesn't work. Any suggestions?
Also, I tried following through your VSCode tutorial but I constantly just run into compiling problems.
Hi. Can you send pictures of how your bltouch is wired and the firmware you used to me? My email is admin@3dprintscape.com
yeah for the final step i dont know if im dumb or if it updated, but how do i kick off the build, there is no checkmark for me
Hi. The checkmark not being there is typically caused by the platformio/c++ plugin not being installed (or the install was bad) or the wrong folder is opened in workspace.
I followed your video step for step. Once you made a change vsCODE I paused the video and made SAME changes. Ok. Mine compiled just fine. I got my ender 3 pro with Mini e3 v3. Well almost. The blTouch levels the center of the bed but when it’s starting a print and lays down that warmup line on left side of bed, we’ll the hot end is still 1/2” off the bed. The abl pin does not extend. And the assembly does not lower to print. I thought at first it was the gcode of the file I tried. So I tried a different gcode and same thing happened. Is there a firmware setting I could look at for this ??
Hi. It sounds like your z offset isnt set, or not set correctly.
what exactly are you measuring on the y axis? nozzle tip to front of x gantry?
Hi. Its the distance from the nozzle to the probe on that axis.
Noticed your comments about the ABL Mesh error after updating the TFT firmware. However, when I do the mesh leveling it only appears to attempt to do it at the bottom front left and doesn't move across the board. to the other points, as I would expect. What am I doing wrong?
Hi. Is the probe getting triggered at the bottom left? If there is a error in the reading, it will just stop there.
@@3DPrintscape I will check, also need to make sure I have installed it correctly.
Progress :-)
1. Installed the BL touch unit and wired it so that the original Z-switch stays in place
2. Installed the required firmware for using the BLT touch from the Bigtreetech Github
4. Restarted the Printer
5. Ran the ABL bed leveling which seem to work this time. Although I have a Y-Axis belt tightner adaptor, which confused things when the bed went to take the top measurement, the bed moved too far forward and grumbled (there must be a setting I can change to change the travel distance, if so please advise) , it was ok after that point and I saved the settings.
The only thing I could not do was set the P-Offset (I think it's shown as Z-offset on your video). I know if I used the firmware which does not require the original z-end stop switch, the function worked to a point. If I use it as it now, it homes the printer. Raises the head 10mm and then should go to the center of the bed, but on mine, it tries to move the head to the left while its in the home position. and I have to turn the printer off as the motor/belt for X-Axis start making a hell of a noise.
Any ideas why?
@@abtrooper82 What firmware did you end up using?
@@3DPrintscape All I installed was the "firmware-bltouch.bin" file, should I have installed the file "firmware.bin" to replace the factory stock firmware first? and then apply the "firmware-bltouch.bin" after or is the "firmware-bltouch.bin" the newest firmware for the board including the BLtouch function. The notes on the bigtreetech github seem to imply the firmware.bin file for the ender 3 does not support BLT, hence why I used the firmware-bltouch.bin" file. Sorry for all the questions
UPDATE : I think I know why - I left the original Z-endstop switch connected to the board, so I'm guessing this will confuse the printer and it's going to assume that the home position for the z-offset is now at the bottom left of the board and not the centre of the board, Correct? Should have paid closer attention to you video if this is the case :-)
@@abtrooper82 The firmware should have been named firmware.bin, I don't think the skr will pick up the firmware if its named something else. Also, the z stop should still be connected in most cases.
Hey! Nice Video! But I have the problem, that when I use z-stop or the z-probe - z-stop my printer keeps moving down. You know a solution?
Hi. how is the bltouch wired?
Hello, thank you for making this video, it was very helpful. I’m stuck one a problem though. I was able to compile and flash my firmware onto my printer, but now when I go to auto home, the auto homing sequence doesn’t even touch the X or Y endstops (which would lead to some collisions later on if I tried to do anything else with the printer). But The Z sequence works with the BLTouch probe just fine. I flashed firmware from bigtreeTech to confirm it wasn’t a wiring issue, and the auto homing worked perfectly fine for X and Y with the bigtree firmware. However there were some problems with the Z home sequence that are more troublesome than they are worth. Anyways I’m assuming this is now just a coding issue. So now I’m trying to make my compiled firmware work. Do you have any suggestions to fix the x and y homing issue? Thanks.
Hi. Can you try one of the builds from my site? I want to try to narrow down what the problem could be.
I ended up restarting with the same btt code. I followed a step by step guide online for Ender v1s and it ended up working. Not sure what the issue was as I was watching several different videos (probably the root problem) on how to code the firmware, but it was definitely a coding/user issue
@@landon3105 Thanks for the update, glad you got it working.
Is there an easy way to avoid the bed moving too far forward when leveling the bed. I have a tension belt adaptor for the Y-Axis which upsets the bed when measuring as it comes too far forward.

Hello, i can`t get the bltouch to run. Homing the z-axis doesn´t work-> stopped. With M119 i get the message z min: triggerd, shouldn`t it open? How can I fix this problem? Z_MIN_ENDSTOP_INVERTING false, changing to true doesn´t work, because marlin can´t compile it.

Hi. My initial thought is that the sensor wires are reversed or the config doenst match how the bltocuh is wired. Z_MIN_ENDSTOP_INVERTING should be false if you are running a build from after June 2021.

Hi. Try to add a random date or number to the end of the file name to make it unique.
Ive followed both your install on the SKR Mini E3 V2.0 where we flashed the BLTouch settings, i installed and flashed the TFT35 E3 V3.0, and i cant really seem to get the BLT to work.
Even when the probe is out it still recognizes it as "home", i cant really figure it out, ive swaped the colors around to match what you did, and even doublechecked with the instructions that the colors are indeed the right way (not that i dont trust you)
Anything youve heard of/encountered yourself and have a quickfix of? Thx in andvanse :)
Hi. How is the bltouch wired, what firmware are you using, and is the z-stop connected?
@@3DPrintscape The bltouch is wired like yours, swapped the colors around and connected the 3pin on the lowest 3 ports on the slot for BLtouch and the red connector on the Z-stop. The firmware on the SKR is for "z homing" (renamed to "just" firmware) and for the TFt35 its "BIGTREE_FRF35_V3.0_E3.27.x"

Hi. Try to clear your eeprom.
Such a great guide, but i feel like im being a dumdum and doing something wrong.
Ive got the creality BLTouch, set it up in the way that has you using the 3 pins on the main port of the board (Swapping my pins in the connector around so they were blue/red/yellow, the blue/red were reversed initially), and then using the "z-stop" 2 pin location on the board.
I got the firmware for the z-homing, put it on an SD card- Turn the printer on, it clicks the BL-Touch sensor a few times, then bonks at me about not being able to enable bed leveling / invalid mesh.
When I look through my options, I see "MBL" instead of "ABL", and no options for the BLTouch. Seems like its not updating the firmware properly, but cant figure out why
Hi. It sounds like it may have not taken the firmware. Can you check to see what under the about/info screen?
@@3DPrintscape From the info screen my printer says:
"System: Marlin bugfix-2.0.x

Followed this to the T, and upon first start, the Marlin blue screen was kind of faded and then turned off. But noticed that if I unplug the BLTouch ribbon connector on the sensor itself, my E3Pro starts up just fine with the regular bright Marlin screen and then goes to the "Ender 3 pro ready to print".

@3D Printscape Hello. I am trying to install my BL touch that I got straight from Creality, but It is designed for the original board... I cant rearrange the wires on the connecter. Can you please help?
Hi. Ive seen the bltouch shipped with 5 wiring variances at this point. I wouldnt count on getting the right one anymore as there is no way to guarantee what your getting. If the one you have doesnt match what is needed, you will need to change the pinout.
i have an issue, after a while my bltouch started to probe off the bed, i tried to rewrite the firmware but it seems to not respond to it, ive done some research and i says i need to reset eeprom which i have no clue to do, any help?
Hi. Make sure your offsets are right, so -44 and -7 if your using the stock mount. The select restore defaults to clear the eeprom. I have written instructions covering the process that may help you out in the video description.
Thanks for teaching me how to clear the eeprom, but the issue still remains, that being that no matter the change i do to the firmware the bltouch probing placement nothing changes
just to make sure im on the same page this section is how you change where the bltouch probes right?

My firmware compiled successfully without adding the “_512k” at the end of the default_envs line. Will this cause any issues when flashing to the printer? Or was this not a problem anymore?
Hi. The _512k is no longer needed. There was a release made to the bugfix line over the summer that removed it. If your build was successful, you should be good.
Great work!
Thanks!
Do you need to change the bl touch wiring on the v3 board?
Hi. If you leave the z stop connected and the bltouch connected to the bltouch port you shouldn’t. That is assuming you have one with the 5pin adapter.
Hello, this Firmware works for an Ender 3 with a BIGTREETECH SKR-Mini E3 V2.0 board... and TFT 35 E3 V3.0...? Congratulations for the video and thank you
Hi. Ya it should work fine with that combo assuming the tft firmware is up to date.
This video worked great.. except one problem. The TFT, by default (I have the BTT TFT35) when I try to enable it, it just fails to compile saying "LCD doesn't support bed leveling" I'm using the SKR Mini E3 V3, as you have here, so.. still working on this to get the BLTouch to trigger. It also seems to have removed a ton of options from my TFT (as in, I can't select type of load, like PLA/PLA+)
Hi. I will need to look into this one more when i work on the Marlin builds for the v3.
My printer ignores both ZSTOP and BLTOUCH, I've done everything exactly like you but with the 5 pin configuration(the ZSTOP is still connected but not in use by the firmware). When I try to home it ignores both stops, it doesnt work properly if I use the bin from bigtreetech but they only do a single probing which is why I wish I could use the custom firmware.
Hi. If it works with the BTT firmware, the wiring is good so it sounds like there is an issue with the firmware. Im guessing it doesnt match how its wired. Make sure you comment out #define Z_MIN_PROBE_USES_Z_MIN_ENDSTOP_PIN and uncomment #define USE_PROBE_FOR_Z_HOMING in the firmware.
@@3DPrintscape so I’ve checked that and swiped them and nothing. My version is a bit different than yours it seems, on min_software_endstop urs goes like X Y Z but mine goes X Y Z I J K which tells me they have changed the software on the download page. Would you mind sending me your configuration files so that I can compare against mine and try them.
@@3DPrintscape nvm I fixed it, BLTOUCH_FORCE_SW_MODE had to be commented out, i guess my bltouch isn’t a good clone then.
@@bomxacalaka2033 Im glad you got it working. The definition of a "good clone" is really subjective. If it works and you were able to save some money then it seems ok to me :).
@3D Printscape Thank you very much for your video! It was very helpful, but I am still having some issues. I have your exact configuration but I flashed the pre-compiled firmware (2.0.7). Unfortunately, when I try to set the z-offset I can't get the z-axis lower than 0 and it is too far from the bed! Could you please help on that?
Hi. This is a common issue with the creality firmware because the leave the software endstops enabled. You will want to take a look at this reference to send the g-code command to the printer ( marlinfw.org/docs/gcode/M211.html ) or i can work with you to get a Marlin build that has it disabled.

maybe I am crazy or just dumb, but I dont have a check box when trying to use the btt version for the skr e3 turbo.
Hi. The checkbox is only there if platformio is installed and the firmware folder that has the platformio.ini file is opened. If verified both of those, try to reinstall the c/c++ plugin.
Shouldn't the Z offset be done with a pre-heated bed and nozzle? There is expansion of each after reaching temp and this will affect the gap, not insignificantly.
Hi. I tend to make the final adjustments with babystepping, which is done when everything is up to temp, but to answer your question. Yes, you should have the nozzle and bed heated up.
So it gives a compiling error with the _512K but works without it should I just use the firmware compiled without the _512K
Hi. Yes build it without the _512k if you can. They made some changes in the latest bug fix release that causes issues with the _512k environment.
There's no check at the bottom left of my hot bar only 2 icons and it says no problems. The only thing I havnt done is the probe to nozzle distances because I don't have my hotend mounted currently
