Great video. I just got the CR Touch installed on my Ender 3 and tried following a few other tutorials for the firmware but nothing seemed to work until I picked the one that you picked. Saved me a headache.
Glad I could help. I found the Creality site to be difficult to navigate.
Thank you so much!!! I spent 2 hours looking for it. Chinese to working!!! Your a life saver
Glad I could help and I appreciate the feedback. I think the hardest part is getting the right firmware from their website.
Thank you! Same thing happened to me and after seeing your video I loaded the same file and it is now working!
Great to hear! Glad I could help.
great video, I watch 3 different one and yours works thank you
Cool, thanks
You saved me so much pain by removing the Z switch like that, you're a lifesaver!
Great to hear. I'm so glad helped.
Thank you so much you solved my issue with the confusing firmware page, it's so messy!
You're welcome!
what a mess indeed man i was suffering looking for the right firmware for the 3D printer Jesus I wish I found this video sooner thank you and I gave a like and sub :)
Great glad it helped. I installed the wrong version as well due to the chaos on their site.
Hello, I´ve followed this video and so far it is working great and it checks the bed levels every time a print is about to start.
I got a question anyway, if I remove the bed for cleaning for example and move by mistake one knob, will it fix the calibration for the next print or will I have to calibrate the bed again and memorize the bed levels?
I could not get the firmware to automatically level the bed before each print. So you will need to do a bed leveling and probably a Z offset check if you adjust the knobs.
thanks for the tutorial it was helpful, one thing though. Is that the firmware file must start with firmware for it to update.
Thanks!
No problem!
I am so confused on the marlin site? there is not a bin file I can find? Any advice?
Well I downloaded mine from Creality. Start here then look for your printer, then the board.
www.creality.com/pages/download
See this clip
ruclips.net/user/clipUgkxycvDaFMY3XBjPCjvmROjnRw6Wb2LTPrX
You have the G28G29 next to each other. It should be G28 hit enter then put in G29. the auto bed leveling should work after that for each new print
Yeah when I first installed this I had not coded with Marlin. The manufacturer's spec sheet said to put it as G28G29 so that is what I tried first.
Had mine bolted on for the last 10kg of filament just now intalling the firmware and figuring my z offset.
Thanks
You are welcome. I hope it helped.
So I just purchased and installed the skr mini v3 along with the tft35 e3 v3 on my ended 3. When I turn my printer on I get an invalid mesh notification
I'm not sure what's wrong. I've never tried this method.
I have a Ender 3v1 with Cr touch installed. Do I need to reinstall the CR touch if I upgrade to Sprite extruder?
I’m not sure since I have not used the sprite extruder but you probably will have to move the cr touch to the sprite.
thank you so much this is a great video. but i have a problem. my Z axis only goes up not down?
You are welcome. It sounds like you might be at the lower limit and if so it will go no further down. If so you need to reset the z offset to zero and then start again.

I'm running into a problem where even though I have found the right firmware for my 4.2.2 board, and I am able to see the options for bed leveling within my printer screen after turning it on, whenever I plug in the CR Touch into my main board, the next time I turn the printer on it just sits there on a blue screen as if I don't have any firmware loaded onto it. I have also unplugged the Z-stop switch. Any insight as to what might be the problem for my case?
It still sounds like a firmware issue. There are a couple of versions for a 4.2.2 board but for me, there was only one that worked. It was buried in an obscure folder on Creality's site. I show how to find it in the video.
ruclips.net/user/clipUgkxycvDaFMY3XBjPCjvmROjnRw6Wb2LTPrX
I would try a different firmware and see if that fixes the issue.
Great video, wish I had seen it before I tried to install by myself. I was not able to move z-axis to a negative position so I estimated a negative value for probe z offset and tried bed leveling to see how stuff works. Then printer starts shaking and halted, and after restarting I cannot move any axis. Does this mean I broke the motor by setting z offset too low? Is there any way to fix it?
The Z-offset is the most difficult part of the process. Their manual and instructions don't really explain how this works.
If the printer is shaking, this is probably a result of the nozzle being pinned down to the bed. The stepper motor could be trying to go lower and cannot, thereby causing a banging noise. Goto to the settings and select "disable steppers" Now manually screw the z-axis higher by simply turning the screw by hand so that the CR touch switch is higher than the bed. Hopefully, this will allow you to start again.
Next verify that the stepper works. The setting is "Move Axis" then select Z and try a small move. If nothing, then you might have a problem with the stepper and/or the motherboard.
I have installed the cr touch with your help thank you very much. I have a problem though. When I select level bed it starts the nine-point manoeuvre but the probe goes past the front of the bed missing it. Can you advise me on how to get the probe to stay further inside the bed area? Thank you, subbed of course.
Well thanks for subscribing, I appreciate it.
I'm not sure why this is happening to you. I did some research and it looks like you can manually set the boundary limits. Here is an article on the procedure. 3dprinting.stackexchange.com/questions/7395/how-to-set-the-boundaries-for-bltouch-probing
If you can work out the gcode to manually do this, then you can add the gcode as a default in your slicer. I do this frequently with the Prusa slicer so that it always inserts the code.
I have the wrong board. I always see boards on amazon is it just plug and play swap?
Swapping the board is not difficult. Another viewer bought the board that I have in the description and it worked. You will need to flash the firmware but that's straightforward as well.
My Z axis homes out and then raises almost 1/2” and stops. I tried the Z offset like you show but it only goes to -9.900. I’m still not close enough to the bed.
Make sure you clear the z offset before doing the procedure. I've had something similar happen to me as well.
I have a question, do i need to fully compress the springs in my bed to make the CR Touch work?, Or it doesn't matter?
Not fully compressed but some compression is helpful. The goal is to keep it stable but not over tight.
before i set my z offset using the paper, how should i adjust the knobs that adjust the springs below the bed?
I take at least a couple of sheets of paper under the nozzle and move the leveling knobs so that it's as even as possible around as many points as I can. I leave the steppers on and use the move axis function to move it around the bed.
Hey I downloaded the same file as you in the video and now my screen is stuck blue? I dont know how to fix it. I feel like this could have to do with already installing the cr touch first? any advice or help would be great.
Your board may differ from mine so you'll have to try another firmware version. It failed on me a couple of times before I found the right one.
Great video. I have one question… where are you making the G28/G29 change? Is it in the slicer, or do you have to edit the Gcode of every build?
The directions call for adding this code at the beginning but it does not work. The bed will never level on it's own.
If I could get the correct code, you could add it all the time in your slicer. I use the Prusa slicer and here you can add custom code for all projects.
on Cura, you can easily make the g29 change on the printer setting that stays all the time.
Where in cura?
@@Brando1317 did you get answer for this? I have never messed with g-code. I think it’s in your printer settings in Cura though. At the bottom of the page
@@AaronTurner-pc5dh I did not
I love this video, i need your help I just installed the CR touch on my Ender 3 Pro. i upgraded my motherboard to the BigTreeTech SKR Mini E3 v3.0 and have download the latest firmware and installed it. when i have the Z axis disconnect from the both ends (motherboard and the old stop) when i home my machine it will only do it in the X and Y axis and not in the Z axis. When i reconnect the Z stop and have the CR touch connect it will measure the distance from the best but print to far away from the bed. i need help trying to understand. Thank you
ok the first thing is to make sure that the motherboard can recognize that the CR touch is the new z stop. You can raise the print head and just use your finger. See this ruclips.net/user/clipUgkxKDK0Hwopf1LkkbFxxieAcSiLMa48HLcw
If it's recognizing it but then prints too far away, you need to store the z offset in the settings.
ruclips.net/user/clipUgkxnZio0NLBXO2LITRxbtdg__FyxbX-e8Gj
@@MyEngineeringProjects thank you!
Thank you. I’ll have to check because it won’t go down in the z axis at all
hi bro, i have a questin. Which firmware version you have, cuz i dont have many options you showing
My board is version 4.2.2 so the firmware I used was version 1.1.2
I have the ender 3 upgraded motherboard to 4.2.7 but when I press the self leveling it doesn't do the 8 points it scans to the left and the probe goes of the bed and the nozzel goes into the bed. What am I doing wrong
First check to make sure the limit switches are working. For the x you can manually click it as the nozzle is moving to home. It should stop when you press the switch. For the z axis, it sounds like the CR touch is not hooked up right. You have to disconnect the old Z axis limit switch and then the CR touch will act as the new switch. Check the video where i show how to check the z axis switch is working. this is likely why it's crashing into the bed.
@@MyEngineeringProjects thanks I have sent the whole thing back was getting to many problems and it's my first 3d printer so have no idea
thank you so much, all i needed was the firmware. never wouldve looked there
Yeah I downloaded the wrong version several times until I figured out how they had buried it on their site.
@@MyEngineeringProjects I don’t understand why, if you watch videos over a year old it looked soooo much neater on the site. Now it’s a cluttered mess
They seem to have an attitude of do it as cheap as possible but nothing further. Forget organized, it's just up to us to figure out where to get the right file.
@@MyEngineeringProjects thank god for people who FAFO for the community
do you have to delete the old firmware once you put in the new firmware. I put my sd card in but a blue screen comes on and it won't go away. I also accidently deleted all of the files on my sd card. and all i have is the firmware. Will it work with only the firmware or do I need more files
The script removes the firmware once it's installed so you don't need to do anything. Sounds like you have a firmware issue. You will have to try another version. Creality's site is really disorganized so you'll have to dig into the folders for the right one.
There is a data file that is stored but it should boot up without it. You can regenerate it by pressing "save settings"
@@MyEngineeringProjects I've tried every firmware I could find for the ender 3 pro and the screen is still blue for all of them. Is their anything else I can do? I have a 4.2.2 board.
What worked for me was to drill down into one of the non obvious folders. I finally found the correct version but it was buried on their site.
I got it to work! thank you soo much!
Awesome
I did this yesterday and it worked today I got the blue screen of death deleted everything and retried now it won’t work. Any tips
There are several reasons for a blue screen. It's hard to say what's wrong but first try to re-flash the firmware. If that won't work, check for a bad connection at the motherboard. Since it did work and now it won't, it seems likely that you might have a connection issue.
On my printer when I updated the firmware I don’t have the control menu I don’t know what to do
I would try a different version of the firmware. Their website that has the downloads is really hard to navigate. Also, check the board version number and make sure it matches the firmware you downloaded.
@@MyEngineeringProjects How would I do that? I don't see any old firmware on the creality website. My firmware for the board number is correct.
I need something that works, so do I need to reflash my firmware to go back to manual. I've had the CR touch on my Ender 3 Pro 2 weeks and cannot get successful print. Ive followed what you have done and most likely 20 other videos always the same mess happens.
If you have installed the hardware, stored the z-offset, and leveled the bed and it still does not work, you may need to look at other things. For example, I've had issues even with the CR touch installed and it was due to the bed being too cold. It worked fine last fall but then got worse as the weather got colder. I turned up the bed and filament temperature and even put a box around the printer.
Getting a successful print means that all variables have to be as good as you can get them. You need to look at bed temperature, tip temperature, a dry filament (one that has not absorbed a great deal of moisture), and also the temperature of the room. If any item is too far out of range, the print will fail.
@@MyEngineeringProjects Room temp 72, bed has been cleaned tip 200 bed 50. Everything is up to temp, 0 everything out, auto home, bring the Z axles to O then go to Z offset (cannot do neg. from the main Z axles) and bring it down to paper thick clearance to the bed. Then I will go to release Steppers and level the corners and the center. Then Auto Home again and check the Z offset and make any adjustments to it. When doing the print the test run just find and left side of the print is normal, back right and back side are off.
With the print messing I have taken paper and ran between the bed and nozzle during the print and find that nozzles is to high for printing in the problem areas, and on the left side the nozzle is correct. It does auto level before each print
So I did not read where you are storing the z offset with "store settings" When you probe you have to save it into memory. Also, I print at 60 degrees for the bed so that it stick better. i shot this today ruclips.net/user/clipUgkxpIH8VI1j320Lj_U5h-QQdPfLzmJUnnGs
I don't have that sensor on my motherboard...I have a V1.1.4. Ender 3. UGH. Thank you for saying that in the video, now I have to return my Creality Touch and not have an autobed leveler. What solution would you suggest? Is it possible to update the motherboard or plug in where the "normal" z reader goes?
yes, you can upgrade your motherboard. Looks like they are about $38. I don't think a modification regarding the z axis plug will work.
@@MyEngineeringProjects Thank you so much! Would you have an amazon link I can go to, or what the name of it would be?
I put the product link in the description. After reading the reviews, some have had to re-flash the firmware in order for it to recognize the touch. If you run into issues, take a look at those comments. I had to do this myself so it's not that unexpected.
Notes from the product description:
Compatible with Creality Ender 3, Ender 3 Pro, Ender 3 V2, Ender 5 3D printer. PLEASE NOTICE: It only plug and play for Ender-3 & Ender 3 Pro. If you want to install it on Ender-3 v2 or Ender-5, please flash Ender-5 firmware. You can download firmware from official website.
@@MyEngineeringProjects This is great. Thank you for making community!
So I have a problem. I can’t even get the cr touch file on my printer from the computer I downloaded the right version and there is nothing else on the micro as card.
There are a few possible reasons.
The version could be incompatible with your board. This happened to me, but I was able to load it. Others have reported versioning issues due to the creality website burying the correct version in some obscure folder. In the video I show what I downloaded the first time where it specifically said CR touch but in fact it was the wrong version.
Is the SD card working correctly? If you used it before on this printer then it's probably ok.
Check that your cables are plugged in correctly.
@@MyEngineeringProjects well I looked at my printer version wich is 1.0.1 and downloaded the right file, I have used the sd card on the printer before but I deleted all the files on it. What cables specifically would I check?
I'm just wondering if everything is hooked up correctly. If a plug is backwards or something, it might cause the entire printer to fail. You might unplug the CR touch and replug in the Z limit switch and verify that your printer still works with your old firmware before proceeding to the CR touch upgrade.
@@MyEngineeringProjects yes it did work before this but it just had some trouble with adhesion
So I’m new to 3-d printers and when I installed this now my x,y, and x axes won’t move at all. Even when I try to use auto home nothing moves. Can anyone help? Also everyone and then a message saying homing failed printer halted pops up does anyone know why?
You probably have the wrong firmware or you have not connected the cables correctly to the motherboard check those two first.
@@MyEngineeringProjects thank you I’ll try to fix it today and I’ll give you an update!
Thank you so much, I've watched many videos but they never show to install the files
Glad I could help
the thing that gets me is the g-code for bed level G29 happens after the hot end is hot so i am putting drips all over the build plate. its PLA at 200 nozzle temp
You could try adding custom gcode to shut the nozzle off then bed level, and then turn the nozzle back on
@@MyEngineeringProjects yes I will be learning much more before this journey is complete! Thanks for the video by the way. It was really helpful and got me going again
minor correction for 9:31, the data is stored in EEPROM so you are free to print with sd card removed
ok thanks
I have 4.2.2 board and I had some glitches on the screen after I updated to the same firmware you chose. I tried updating to GD-Ender-3HW4.2.2SW2.0.8.2CRTouchFilamentEuropeMulti and it seems to be alright except from being in chinese, but I managed to change it with the help of google translate. I'll update if it works later.
I'm not sure what went wrong. Keep me posted.
@@MyEngineeringProjects I found a video of some guy saying that some 4.2.2 boards have different memory sizes which causes screen glitches on some firmwares. This version worked for me and after fixing nozzle heating problem with PID tuning it works great. It feels so weird hearing Z motor all the time but I'll get used it. Thanks for your video, it really helped me with the installation.
Awesome glad you got it working. I was not aware of a memory issue but that's good information.
I’m trying to add the firmware but it’s not updating or doing anything to the printer could I have some assistance
Make sure you have the bootloader installed. If so, then try a different firmware version.
@@MyEngineeringProjects what is a bootloader?
A bootloader is the program that allows re-flashing the firmware. If you printer is bricked, you may need to reinstall this before re-flashing.
Hello, nice video, but I have a problem
When I try to start my print, it freezes after 10 seconds (and freezes the control panel).
Does anyone know why?
Also, do I need to "level the bed" for each print or do the "store settings" save it and I can do it like all 3/4 prints?
Thanks for your help
I guess I don't have the right firmware, I have an ender 3 (classic), it was in 4.2.2, so I took the same firmware as the one taken in the video
I don't see which one I should take
Yes it sounds like a firmware issue. There are several version for the 4.2.2 board so you have to dig around and try again.
You can program in the bed leveling routine with your slicer g28; g29; on separate lines.
no, you don't need to store settings every time. this is just for storing the z offset
@@MyEngineeringProjects i already try some of them, but thx for your help, i will continue my research
Followed the instructions and now my sd card isn’t being read. What do I do?
This is most likely a firmware version issue. Look at your board, find the version, and try another version from Creality's website.
hello everyone if your having issues with the firmware not downloading on your 3d printer when you put your SD card in rename it 123 it works.
I do not know if you got the G29 to work but the way you did even though it is the way creality tells you to do it, it is not the correct way and when i installed mine I also had the same issue with it not working as the writing in the instructions said to change G28 to G28 G29 which implies on the same line but i did not notice the little picture above had the G commands on separate lines, the picture is the correct way to have G28 and then go down one line and put the G29 command below it
ok I'll try that. Thanks for the tip.
I did the same thing at first because the crap paperwork said G28G29 lol!
Also if you don’t want it to do the whole process again you can do “M420 S1 Z10 ; use bed mesh saved in slot 1” that will load the saved mesh
@@franktank9573 Indeed, the G29 works and is a minor inconvenience as the stock firmware only uses 9 probe samples, but after posting here i created a custom version of Marlin that has 81 probe points for better accuracy so quickly changed to M420 S1
@@franktank9573 I am really a noob and not sure where this should be done. Do you have tutorial or pictures?
When I put in my Sd card it never loads and stays on a blue screen
This is likely a firmware issue. You might have the wrong version installed for your board. Double check your board and the version you downloaded from Creality's site.
I have a problem and I hope to find a solution for you and the viewers of the channel
I have an Ender 3 E printer
I added an additional z-axis to it. The two motors were connected with one cable
I installed CR Touch
I'm having a main shaft chopping issue with a humming sound and the chopping action causes the nossle to be out of balance
What is the solution?
If you hear a clicking sound when the filament is trying to extrude, this means that you have a clog in the line. The clicking sound is the stepper motor turning and then snapping back because it cannot move forward. Start at the nozzle and work your way backward to the extruder.
im confused, at 9:00 I cannot lower the value more than -9.900. Help me.
I have not had that problem but it might mean that you are too far from the bed. Be sure to let it come down on it's own so that it can get close to the correct height. If you notice in my video, I put my finger on the switch as a test, but then went back and let it lower itself all the way to the bed.
I now know why this can occur. This happened to me today. I'll post a video to explain. in the meantime, the reason is that the printer needs to be moved to Z 0 where it thinks 0 is at. Once you are there, you probe from that and it should work. If you probe from home which is 10 mm higher, it won't work.
Hey how long does the firmware update take? I think I may have bricked my printer. :(
About 30 seconds or so. Try to upload a different version if it's stuck.
@@MyEngineeringProjects Yeah I had uploaded the wrong firmware and bricked the printer for a while until I found the right file. Amazing video once I got past my problem, Thank you
Great to hear that you got it working.
9:10 just some minor mistake, it flashes it in the board's EEPROM, not SD card.
Ok thanks.
When I go to do the probe offset it doesn’t go low enough…
Be sure to reset the offset to zero before proceeding. If it still won't go, then raise the bed itself using the knobs underneath.
Im so confused, how do you put the SD card in the PC? How do you put the info on the sd card?
There is a small adapter that allows you to plug a micro SD card into your computer. Check the product description.
See this section of the video for how to transfer that firmware to your card.
ruclips.net/user/clipUgkxu2Lf0z1voDKDKVQVkkLMzN95BgckaJ7v
@@MyEngineeringProjects So I can’t download the firmware to the as card without that adapter?
You need the adapter to put it on the card. After that, you insert it into the Ender
You can also use any SD card adapter from your camera or phone, it's just writing a file to the card
The Creality Download has been updated and is better labeled now.
That's good news.
CR Touch is supposed to do a 9-point bed leveling check. Mine only stops at one point. That's it. Any ideas? Btw, your video has helped me so much. My Ender 3 was completely frozen. Now it's printing but I need to get the bed leveled.
Glad to hear that it helped.
Have you added the gcode to do the bed leveling? You need to add G28; on one line then G29; on the next line. This should be done near the top so that it measures the bed before you print. I add mine permanently with custom Gcode in my slicer.
You can also manually do this by going into the settings and initiate bed leveling.
@@MyEngineeringProjects It's in there like this: G28G29 ; Home all axes and bed leveling. It's the second line of code under: G92 E0 ; Reset Extruder
@@MyEngineeringProjects Thank you for your reply. I put "G28 ; Home all axes" on one line. "G29 ; bed leveling" on the next. Minus the quotation marks of course. Still not doing 9-pt test. Using Cura.
So your video is good... but ya skiped over the part i really needed. how did you GET the Z-offset number? not where you put it, how ya got it.

Creality figures, "We make it cheap, and that's enough." It's the exact opposite of Apple who says, "We make it expensive, and we adore you." Isn't there some happy medium in between?
Maybe a Prusa. I've never tried them but some swear by them.
@@MyEngineeringProjects For sure. I have until Jan 31 to return all my Creality stuff, so I'm going to hammer away at it some more with firmware being the target (I have both Sprite and CLtouch addons and Creality doesn't seem to have a single driver for both). I'm ordering a BL touch today and will try it. If all else fails, definitely it's a Prusa.
These are hobby machines for people who use them as a hobby. Not pro machines for professionals who want to push a button and go.
They make decent quality at a less than decent price so I’ll take them any day
@@jhondoe1483 I agree. We need a low end. Many of the things I buy are low end. I'm saying I'd like something _between_ a $300 Ender and an $800 Bambu. (My Ender killed me and $850 for a Bambu was more than I wanted to spend.. past tense, I reluctantly did).
@@workingTchr well really creality makes a lot of printers in that gap.
Really understand a ended 3 is a prusa printer made as cheap as possible. (No linear rails etc) an ended 3 pro is a little more in the middle, a v2 a little more, a neo a little more… etc.
Creality basically took and open source printer and made it as cheap as they can while still remaining functional. They now sell half a dozen that stretch from basic bottom of the barrel to with the k printers now high end.
The Code is suppose to be like this G28 ;Home and under that next line G29 then it will work
Yes that's right, thanks.
why have they made this difficult to navigate the firmware they need to subtitle each download to say this is cr touch and bl touch farmwear thank you for this
The page was probably posted by developers who simply made all code available with no regard for ease of use. It was just a mess.
Their firmware page is so annoying. No versions, just random names strung together
Yeah I hear you. I had to try a couple in order to get it to work.
Why do you set the z offset exactly one random piece of paper too high? You are telling the printer “that is your zero height” but you have set it at zero plus a random bit of paper…….why?
I do one piece of paper for the actual probe. See this clip ruclips.net/user/clipUgkx9Zt5NWmynSjB49YG-OsmefEXWfeBdWLx
For the manual bed leveling using the knobs, I have found through experimentation that one piece of paper leveling is not necessary. For my printer and bed, it is so tight that if I make one mistake, it will drag on the bed and ruin the nozzle. The CR touch is capable of going down an extra piece of paper. This is done by probing the z offset which tells the firmware how far down to go. It is here (at probing the z offset) where I use one piece of paper.
@@MyEngineeringProjects if the firmware needs to know how far the nozzle is from the bed when the sensor homes why tell it a figure that’s not correct? Sorry but I still can’t see the point of that. The firmware sets how far the nozzle is from the bed when it prints except it can’t do that if you give it an incorrect z offset by adding an unknown height of a random piece of paper…..take a look around any precision engineering shop and you won’t see any engineers using bits of paper for anything else but writing on.
I'm referring to the total distance using the knobs for rough leveling, not the z offset. The z offset is probed with one piece of paper not two. The firmware knows exactly where the bed is since I probed it with just one piece of paper.
@@MyEngineeringProjects it doesn’t know where the bed is…it is being told a figure that is a random piece of paper above the bed. When you set the z offset what is the distance you are setting…..the firmware thinks it’s the distance the nozzle is above the bed when the probe is zeroed….is that what you are telling it? Or are you adding a random bit more for some reason? I’m not trying to blame you for anything this is a belief that for some reason has become firmly entrenched in the 3d printing community……do we add a random bit to the e steps? Or anything else? Just the z offset apparently. The height the firmware is going to print above the bed for the first layer is set in the firmware but for some reason many people think it’s best to just add a random bit to that by entering an incorrect z offset value.
You’re overthinking the situation way too much.
mine is still in chinese? help lol
Not sure what version you are using, but for V2 Try navigating to Prepare which is the top right, then going down to the A symbol which is just below the temperature symbol, then you should be able to find English. For other versions this would be different.
