- UPDATE: Much of this is relevant, but you can no longer use Arduino to easily compile for 8 bit boards. Fortunately VS code with the Auto Build Marlin extension makes it better than ever. Full guide here: • Updated Marlin firmwar...
By request: a beginner’s guide on editing Marlin 3D printer firmware. This video explains what firmware is, the differences between firmware source and compiled firmware, where to get the firmware and editing software, basic concepts, specific scenarios, uploading and troubleshooting. Once you overcome the initial barrier, things will become much clearer and you’ll lean quickly.
Thanks to the Marlin developers for providing free, capable firmware, with a large range of premade configurations to help us out!
If you have any great tips for beginners, please add them in the comments.

Am in the process of upgrading to a 32 bit board and lots of new features. So have gone through yours and other videos and developed a "checklist" to follow to make sure each one is done. Saved me a bunch of time and helped keep the first list of errors short.
Thanks for the excellent presentation.
Your videos have saved me several times over now on getting my Creality gear up and running the way I wanted. Even just trying to get a BLTouch working on an Ender 5 almost left me wanting to throw the machine out the window, but your walkthroughs got me through it. Thank you so much!
Did you have an issue with your nozzle being way too high off the board? I am having that issue with an ender 5 with BL touch and nothing I do is getting the nozzle close enough to the plate during a print. I've set my Z axis and my Z probe offset as far negative as it'll let me and it's still probably an 1/8 inch too high.
If you didn't make this video, I would not be able to get my printer up and running the way I want it to. You are amazing. Thanks a ton!
The amount of content you produce at the rate and quality you produce it at is pretty incredible.
everybody does marlin configuration videos these times - and that is AWESOME! :D perfect for me who currently makes a hevo. Thank you so much, Michael for your videos!
Only one recomendation is to add a unique label comment to any line that you have modified so that you can easily search for any modified lines in your copy, for commented lines add this label to the end of the existing comment rether than deleting existing comments. Thanks for all your work!
Or use git, It's also built into Visual Studio Code so you can easily see the side-by-side diff.
Again Michael, your video with this subject was right on time! I’ve done some major mods to my Ender 3 and now it’s time to add the Marlin 2.0.x software! Keep up the great work and thank you for your awesome videos!
dude you need to know this video is still helping people, I was massively stuck I went looking for answers, watched 2 of your videos on compiling marlin and it was like being struck my lightening. I've been 3d printing 3/4 years and if I'm ever stuck its always your videos that rescue me Thank you So much.
I really enjoy your tutorials. I taught technology in Primary, Secondary and Tertiary settings for 45 years and loved every moment of it!
The explanations that you give are helping me to keep my mind and hands active in my extensive home workshop as I enjoy the lifelong learning challenge.
I really appreciate your easily understood, no frills, clear instruction.
Congratulations on being a consummate educator.
This was incredibly helpful. I just upgraded the motherboard on my Ender 3 and really wanted play with the features in Marlin but had no idea where to start, even after reading for hours online. Your video saved me so much time and stress.
I have been searching everywhere on the internet for months and asking for help, but finally found this video, very helpful and has given me the courage to go again. I have an ender6 with BL touch and want to use the Sonic Pad, but it doesn't work properly because BL touch no longer responds, probably have to adjust the printer.cfg, your video has given me a direction to continue my search, thanks!!
Wr,Henk
Michael, you have done a nice job explaining the details clearly. I was editing my marlin firmware at the same time :) it was fun.
Great update to vids you did a year ago. A lot of new funtionality in Marlin and a plethora of new hardware. Thx
Perfect timing. I’ve been wanting a tutorial like this. Thanks!!
Thank you very much for this video Michael! I needed to center my build plate (a large print will print off the bed even though it's centered in Cura) and this is the video I needed to point me in the right direction with how to use Arduino and how to compile and upload the firmware.
This and the other guide where you go through the Atom setup was so key. I now got the latest SKR Mini fw for my Ender 3. I didn't even bother tweaking any settings yet. It's got (semi) auto bed leveling enabled by default!
Thanks for your help! Oh, and you talked me into that direct drive, too. It's on the way. I'm gonna need to watch that video again so I know what settings to tweak.
This is exactly what I needed. Thank you very much!
ETA on my 3D printer is about 4 days from now. I’m spending all my free time binging this channel, so I have a decent idea what I’m doing when it arrives. wish me luck!
Thank you, thank you. You made an olde pharte really happy with this instructional video. Was able to do it all and it felt great.
Thank you for the detailed instruction. Had been using your videos since I learn how to mod my printer. Even learn some new tricks on VSCode.
Thanks Michael, good video. My tip would be to download the source get it to compile, then add your printer default files and then check it compiles. Make changes in increments and check it complies. Don't make all the changes and then see if it complies or you won't know which change has broken the code. You'll find it's a love/hate thing - it's great when you get it going on the latest code with the options you want but hate when you try and do it and you can't get it to work!
I'm just starting out and I have to tell you, the struggle is real!
i dont understand why sometimes when i brin the marlin fw in to VC some times it will come in with the env already done and marlin auto will compile it and sometimes it dont do shit .. do you have any pointers on how to bring it in and how to set up vc
This is a very humble pie you have served up here! Even I understood it!!! GLORIOUS!!!
Hey dude, unrelated to this video, but I wanted to let you know that I am working my way through your website right now and it is amazing. Thank you so much for creating such a valuable asset for the community. I just happened to click on one of your videos when searching google for instructions on compiling my own firmware and boom, there's your face. Anyways, I'm up to the acceleration/tuning tab of your site and my print quality is already worlds better than when I started. You wouldn't even believe the prints are coming out of the same printer. I finally decided to tune everything after spending a bunch of money on a Micro-Swiss direct drive and a BLtouch and still not seeing improvements. Turns out I only had to spend time learning how different settings affect my print quality and tweaking them. I could not have done it without your site. Thank you so much!
One small suggestion I might add if you don't mind is that it would be nice if there were a section to enter a z-offset into the code. My printer really needs a negative z-offset for the first layer, and I haven't been able to figure out how to do that through start code alone. But that's just one small thing. The service overall is amazing! Thanks again!
The trickier part comes when you don't have a preconfigured code for your printer and you have to go through all the scripts and pray when you turn on your printer after uploading it. In my case I have tried compiling many many times with no success for my cr10s pro v2 as there's no preconfigured source code for it, or at least I can't find one. But keep up the good work, it helps a lot 👌
Michael, you're the best. Thanks for the help.
Thank you for this. you have really built my confidence with this. I'm subscribed now. Thank you!
Thanks bro! I was kind of pulling out my hair trying to get it to work. But that should definitely help!👍
Teaching Tech, CNC kitchen, Thomas Sanlanderer, the triad of 3d printing knowledge. These channels are indispensable.
thanks alot! been needing a full understanding of this
Great video with great timing! Got the almost 2 year old Ender 3 upgraded with a SKR mini E3 and this was a big help in modifying the firmware. So much easier than that first Melzi flash and tons of room to spare!
Ok , this is making sense now. Thank you for this.
been the 3rd time you upload a few days before i need something. Are you watching me??? hahah
Great video very clear easy to follow. Thank you.
Thanks for the video. I bought a BL Touch for my Anet A8 and have been holding off installing it until I get a better handle on the Marlin.
Great video. Couple of things ive found add confidence to new users. 1/ Explaining the VS code is just a glorified text editor . 2/ VS code takes away a lot of the pain that was Arduino IDE ( i'm thinking mainly the IDE version issues and loading libraries etc. 3/ when you've downloaded the latest "bugfix" version of Marlin try compiling it before any edits are made...that way you know your VS code setup is working correctly. 4 / For added confidence test compile while editing .For example adjust temp sensors / endstops config then test compile If that works add esteps and bed size then test compile again.
It would be good for Mac users if you explained how to make ( for example) the PIO folder visible :-)
Cheers
But what if I need to change the firmware that is already on the printer?
I have an Anycubic i3 Mega S Firmware V1.1.5 which is still Marlin and I only need to change the mA current of the stepper motor. Ho do I get inside my Printers's firmware? I don't wanto to change it, I just want to tune it...
You do good work man. I really like that your videos are spot on and without the fluff and stuff, or just rambling, too may youtubers do. Concise and to the point. Well done!
I've been wanting to modify the Marlin 1.5.2(alex) for my Voxelab Aquila (great first printer) to crank it up to 300c on the hotend. I've already upgraded to all metal hot end and Boden tube. I'd like to start working with materials that need over 260 default. Per the Voxelab site, it's the same main board and thermistor for the Aquila and the S2 which is sold as a 300c machine. So, this should make the modding firmware task relatively easy. I just started messing with coding and Python at that. So... never messed with compiling. Should be a fun first task....lol
Thanks man..,cheers!
Thanks again - just what I needed. Much appreciated.
This is the easiest to follow instruction set I've found, thank you. Now my ageing ender v1 can actually use its direct drive full metal hot end to its fullest instead of just picking the "4.2.7 bltouch" compile from the creality site! And marlin 2.1 to boot
Thanks for the clear instructions and explanation.
Very clear explanation for beginners like me.
perfect timing. thanks dude, very well
Thanks , It really helped a lot !
You know he’s the real deal, he starts his video with an if/then statement.
else
While
I’ll be using this soon on my diy IDEX build. I hope it goes well!
Hi Michael, great video. Really clears up the firmware, keep up the good work.
As usual... Very helpful. I sort of combined this with the GitHub install and setup you had a while back... And I keep getting a 2 warning in VSCode, but I looked at your screen in this video, and you have the same 2 Warnings in the c_ccp_properties.json. I am not sure what the include folder does, but I added it to my structure and all is happy now. Just in case someone else is beating themselves up over this :)
Will it work with the Creality 32bit silent motherboard? That's what I'm running, using Marlin and a BLtouch.
WOW!!! WOW!! WOW!! I have worked my way though this over and over!! WOW! thank you !! I have learnt so much!! still have no idea,, but less of a no idea, of what the hell I am doing!! thanks
Hi ,, just a side note, I see some people do.. So I have a mega 2560 with a display,reprap and am trying to build a , well I have built a camera slider with a turet, that was the ezze part,, now to load software so it will run. That is the new learning curve.. Did not realize I would have to learn C++, but thats cool.
Oh bro you are a genius.thank you from my heartiest.thank you very much.
Hello Michael, you've covered Marlin and Klipper on your channel. Which one do you primarily use with your printers and why? Thank you
Hello Michael. First Thank you so much again for your videos which are so helpful since documentation for Marlin is so sketchy.
Quick question: once you've adjusted the extruder steps/unit value (by extruding and then measuring a set length), do other values (such as feedrates, accelerations, etc) automatically take this into account?
For instance, if I go from a direct extruder to a geared one (3:1), does the only value I have to change is the steps/units (and then everything else will be adjusted accordingly)?
Thanks in advance. Great work! :-))
This is very helpful!!!
Love all your content and pointers. You have helped me set everything up but I’m totally lost on the whole software/firmware stuff! I did a bunch of changes and now it doesn’t even work lol.
Hey I was looking in the configuration advanced section, where I saw a code line commented for cnc spindle and laser, I was hoping that can you please explain it in a video.Thanka
Got all my settings done, compile and got an error as there was no output or com1
The Marlin Github Configuration example files have Configuration.h and Configuration_adv.h and possibly other .h files already configured for many different printers. Those files should be used instead of the default Configuration.h and Configuration_adv.h that are in the Marlin Github files. I might have missed it, but I didn't see a good explanation of how to find and use the proper configuration files. Really helpful video, thanks.
I really appreciate your videos.
I have a question for you and I would like to know your opinion, so I am trying to upgrade my Geeetech A20T to add a 4th extruder. Do you think is possible to use a PWM pin on the GT2560 Board and configure the pins using the marlin firmware? So when update the printer using CURA to configure the 4th extruder and create the design with 4 extruders and the GCODE will then activate each extruder?
Hope this question makes sense and hope you could give me your opinion.
Thank you
thanks just what I needed
Hi Teaching tech, thank you for recommending this video. Do you have a video where you show specifically how to add the automated filament changing feature (IE the one where after you preheat the pla you are given the option to change filament which will extrude the leftover filament) I completed the process you laid out in your updated video, and the resulting firmware is missing this feature. if there is no video, can you just let me know what in the code I need to uncomment to get the feature?
I'm running into a issue with running out of space on my stock ender 3 and idk what board i need in visual studio. A couple of these how to need to be updated.
Very cool video!
What settings do I have to change in order to have the Filament Run Out sensor pause the print and not allow the Bed to cool down when the filament runs out..
Thank you!!! Everybody starts with getting vs code and then sends you to get the configurations file. They totally leave out the fact that you have to have the main marlin file, that is a separate thing!! Trying to figure out for 2 evenings why my zipfile was missing a lot of the files and folders, such a waste of time..........cant believe it such a simple thing
Great videos. Quick question, I have a Ender 3 V2 but in vcode I have no platformio.ini. Should I have this?
This is a great tutorial.
For those who experience the same torture as I did:
Sometimes after flashing a bootloader vscode won't recognize that the printer is connected. Thus, avrdude gives an error message saying he can't find the chip. Looks something like this:
avrdude: stk500_recv(): programmer is not responding
avrdude: stk500_getsync() attempt 10 of 10: not in sync: resp=0x18
Well. If you compile Marlin it saves the actual .hex file. Go on and install AVRDUDESS. Set it up for your printer (there are tutorials on youtube) and voilà. AVRDUDESS kinda forces the write, even if it can't detect the printer. However, when reading for check it finds the printer.
Worked for me, took one and a half days to figure out
great, thanks dude
Can you tell what is the most reliable configuration.h in terms of default values (regardless of the Marlin version) : the one provided by the manufacturer, even if it's a bit old version of Marlin (ex : 1.8), or the one provided by Marlin for the same specific printer (ex : for 1.9.1) ? I mean for example, You when thos 2 files give different values for jerk, speeds, PIDs, Kp, etc...
If I haven't upgraded my printer, now there are several firmware upgrades on the web site, do I have to do it in order, from the oldest to the newest, or is enough to upgrade firmware only with the newest?
Thank you very much sir you're the best
Thanks for all you do , xoxo
Thanks a lot for the video!!!
Dear friends! I am building a 3D printer and I need your help and advice. I have 4 stepper motors on the Z axis.
Question -
How can Extruder 2 driver be used in Marlin as an additional drive for the Z axis (so that there are two drivers on the Z axis that work in parallel (each of which controls two stepper motors)
Thanks in advance!!!
Hi,
I have a question about the building from scratch 3D printer. for my idea, I would like to have 4 PMW output to simulate the extruders as I am using actuators that need this type of signal. So my question is, Can I use 4 pins on the RAMPS board and assigned as extruder on the Marlin firmware and when I slice the design using Slic3r with the 4 different colors I would be able to activate this 4 pins with PMW signals when the Pronterface perform each extruder?
Hope this question makes sense and I could hear soon from you. Really appreciate your content.
Thank you.
Hi Michael, thank you for all of your videos, they're so helpful! I wanted to know if you or anyone here can tell me, does Marlin use E values or absolute values? Thank you!!
Hey Teaching tech great video, could you please shine a light on why my VCS keeps showing me the error ''please update your includepath. squiggles are disabled for this translation unit'' It's driving me crazy now I'm trying to fix my SKR Mini E3 boards because they've randomly gone loud again after being quiet for some time. :(
TIA
How to add power loss recovery in Marlin , I'm using DIY 3D printing machine please give me suggestions so I can use some hardware and software changes to enable Power loss recovery
How would I know if I need to have the 512k after my board type in the platformio file? My board is labeled just SKR Mini E3 V2.0 on the board itself and doesn't reference 256 or 512 that I can see
thank you for your precious video !i've one issue ! I bought Skr mini e3 v2 , and i compiled the correct firmware, it works perfectly BUT if i change some values (like i did with : #define SDCARD_RATHERRECENTFIRST or #define POWER_LOSS_RECOVERY or //#define SCROLL_LONG_FILENAMES ) than changes are NOT seen on the ender 3 ... why?
i saw " one like " now .. i reply to myself , after using a newer marlin firmware 2.06 that fixed this problem! so #define SDCARD_RATHERRECENTFIRST but UNDEFINE //#define SDCARD_SORT_ALPHA
Hey Michael in the creality examples for ender e. It gives all the btt boards for the minis and 1.3 versions and option for e3 turbo...is that the skr 1.4 turbo or something completely different. If so what would the 1.4 turbo be considered since its n5o actually mention in the list anywhere?
Do we need to connect to the printer when compiling it? Or we can compile it then put the firmware into sdcard and update from the machine? Doing it on visual studio code, with stm32 processor
so i got Visual Studio Code but i dont have all the stuff at the bottom like you do. is there a keyboard short cut that does the same as clicking the check?
mate....u r awesome
Great tutorial, but stuck at compile. No platformio.ini in, Prusa-Firmware-3.9.0, source and no compile option at bottom of Visual Code Studio.
awesome. i have a 3 day print running right now but as soon as its done im going to install my bltouch on my mini e3 v2.0 board and flash the firmware. im lame and have been looking at the bltouch not doing anything but looking nice on my hot end because i was worried about the firmware. still need to figure out what wire goes to what pin though
Michael, have you checked out the new marlin rtos 2.1. Everything seems extremely vague to say the least and theres nothing about a solid setup process either. Or what it show go in or not go in. But I assume they wouldn't put it up if it wasn't ok to use. Nobodys done a video about so im curious
With the folder path issue, I have also found sometimes that PlatformIO options (build, deploy ect.) do not even show up at all.
Can you help me, I can't seem to find the .pio folder :/
Probably the best and clearest tutorial to date. 👍
Michael, I have many questions as I am truly a beginner. What software were you using to access the printers firmware..Arduino? In trying to update the firmware on my V 2.0 BigTreeTech board (Ender3) I managed to ....I don't know the screen is blue and won't go anywhere. Is the way to recover? if so can you do a video on how. If there isn't I guess I reinstall my original Ender 3 board. Not particularly upset about this just want to learn. I don't know where you find the time to do all of this.
what is the chance to see your configuration & configuration_adv.h setups? for your Ender 3/5?
Thanks for all the help man. Love these Vids. But I installed an SKR Mini e3 v2.0 with bltouch and something serious happened where it wont home properly anymore. Im getting an Error that says Printer Halted: Homing Failed, Please Reset.... I found out that i could set it on the homing switches with the steppers disabled and home it and that got it past the Error and through the extruder cleaning line... but as soon as it started to print it though the homing sidf the Build Plate was center.... I need some help...
Great video. Was curious if you have an opinion on jyers which is what I’m using now? I installed a Biqu h2, dual z, adjustable y axis on my ender 3v2. Gonna be upgrading my main board and considering the skr pro v1.2 mostly cause the amount of ports and the price along with wanting dual extruders, ender extender, independent z control, big tree touch screen and a few other upgrades. Does marlin 2.0 have advantages? I got used to not needing to link to a pc as I have no internet access at printer location and a desktop that’s not so movable in a different building. I noticed the skr mini e3 there’s a few people running jyers in marlin configuration. Wondering if that’s possible with the skr pro v1.2 or if marlin 2.0 is fully usable without ever linking to a pc. Eventually I’ll have internet at printer but I need to boost my signal as it falls short by about 30 feet on WiFi signal. Sorry for the complex question. Only been printing for 8 weeks. Installed the biqu and dual z on my own but I mod a lot of items so that was easy. Marlin just looks scary but I guess everything does at the beginning. Thanks many of your videos helped me do these mods and get me printing decent after. I know the boards extravagant for an ender 3 but I researched printing for a few years and know where I’m headed and I’ll be using 5 of the thermistors for sure.
Good video. Can you tell me why when I try to change the baud rate in configuration H of Marlin that the Arduino IDE software will not save the change ? It keeps saying the Marlin.ino already exists. I can save changes to any other sketch but not to Marlin. Please help, thank you.
Please help I don't have the little tick after making all the edits I need to run my new e3d hemera, thanks
HI.
I am useing cura, and abl i have an ooes problem. When abl checks level the hot end is heated and ooes is comeing out. is there any way to set heat nozzel after abl check. I have looked and just cant seem to solve this. Cura add heatup before start gcode. can i change where cura adds the nozzel heat up
Thanks
Hi, do you have a play list of firmware related video? I am new to 3D printing and want to watch more about its firmwares.
I’d like to see if and how you can save the existing firmware file as a backup before flashing a new firmware to a machine. Also how one would restore the backup in the event something did not work as expected or even if the board failed to boot as a result of a new firmware.
i´m altering marlin code not often and keep forgetting how to. I have installed a rapms fen extension board. Now i should assign the pin for servo ac 6 and 11 (i think) but how do i find the ramps pins in marlin 2.0 and visual code as editor?
Thanks bro!
hello how do I configure to change the hoteds, as well as in the ultimakers?
Hi Micheal, i am having problems with Ender 3v2 printer, i have installed a CR Touch downloaded the update which works fine, but the on item i have been able to print out was the dog that was already on the tf card, when i try to use a .stl file from Thingiverse using Cura and slicing for the printer it will only print the base layer then the printer just stops it seams to lock up and i have to switch the printer off at the switch for it to work again. any help with this would very helpfull
Hey I got a CR-10s on my 14th birthday an it worked for a couple of days but when i tried to install E3D chimera,
my hotend1 starts to heat up when powered on and I cant control the temp I also have 2 port for the heater catridge(I am using creality v2.2) so can you make a video on setting the nozzle 2 as default nozzle or any other fixes
It is very depresssing as i was waiting for a 3d printer for years pls
