Hands down the best guide I have seen so far. To the point, with proper explanations about what we're actually doing and not just "follow these steps". Thank you!

Has anybody else ever had those days where you search for something simple on Google or KZfaq but you just can't find it not matter what you search? I get that a lot! I think the Google Algorithm hates me. It always provides me with the most irrelevant things you could think of. I gave up yesterday and decided to look for something else, this video was the top result and my new search had nothing to do with 3D printing lol. Thank you bro, I saved your video so I'll never lose it!

Truly appreciate these videos from many creators. I finally took the plunge into learning how to edit and compile marlin after needing to replace the main board as the stock one was locked down and was replaced with a robin nano v1 2. I encountered so many errors and messages that literally meant nothing to me but i worked through each problem one at a time and managed to get a build of marlin 2.0.9 to compile and install. Then I was able to work through modifying individual issues that crept in and then finally set it up for my specific needs. I was left in a situation when my bl touch wouldn't trigger and i tracked that down to the z min on the board so i figured it how to swap the z min to the E1 stp pins and bl touch works perfectly. I finally got all of that and used it to do a build with the most recent version 2.1.2 i think) and it's exactly how i want. I even figured out how to modify the colour scheme for the background and menus without any help. Once i understood how the Marlin layout worked i found the settings i needed in the tft-color.h file and played around until it was just right. So basically a huge thanks for making a video like this.

BEST video I've seen to date on the Marlin process! I'm no dummy but without a couple of small bits of info you covered, I was struggling a bit. Thanks a TON!

Past many days I was searching for these kind of complete support for the modification on firmware, Finally I got in here! Thanks for sharing your expertise.

best guide helped me first time compile the marlin successfully

This video was a huge help when setting up my printer...Thank you for making this.

This is by far the best and easiest to follow video on this subject. I got myself in a right mess,courtesy of two other videos that leave out key info, I'm fairly computer literate but I'm not an expert, this guy walks you through step by step and I have my Ender5 Pro up and running with 4.2.7 board. My only issues are I have a CR touch and could not find this listed, the other issue which didn't help with the first is my version of VSC doesn't have a search box within the configuration H and ADV. I tried highlighting text within as you seem to do, but nothing. One other thing was when I loaded the bin file on the printer it came up with " EEprom Version Error " after a quick bit of research I pressed reset and it all seems to work,with the exception of the bed leveling. Despite those problems it's working and you really helped me out. Thanks 👍

Thanks for the explanation on all of the steps. Very nice job.

Finally got it working! This is exactly what i needed, thank you so much

Thank you so much for making this,and also for focusing on your screen, I have tried to follow other vid and could not read there screen,Thanks again!!!

I know this is a year old but it’s still an excellent tutorial. Thank you for the crash course in messing with code. I think that’s about as deep as I want to go.

This was a very concise how-to video! Thanks for sharing 😊

2 thumbs up on this vid! VERY well done. Thanks you so much!

You've been a great help right to the point and access location. People don't have the money to fix their problems by professionals, so it's nice when people such as yourself help out the little guy and they can get back to their lives again.

Very helpful. Thank you so much for the info.

Thank you, well explain video. Help me a lot with my build!

this guide helped me. thank you. I did a Ender 3 pro to a V4.2.7 board. the only thing that tricked me up was i had to add the boot screen from the creality folder that you grab configs from. otherwise it will fail when trying to build. other than that this worked like a charm!!!!

very clear and precise guide. finally got linear advance on my ender 3 neo since creality's newest firmware release for it is marlin 2.0.8

Thanks great video. I know how hard they are to put together.

Great topic, thanks

got it up and going on a ender 3 max thanks

great video, helped a lot thanks 👍

Phenomenal video, I feel like I made a lot of progress, but still stuck. Constant bed levelling led me to get the BLTouch and end up here following your instructions word for word. I feel like my printer is on the cusp of greatness. Unfortunately, after two firmware flashes for the ender 3 pro with a BTT SKR V2 board, all that happens is the printer homes, heats up, and then "progress" bar rapidly proceeds to 100% as if it's finished when it hasn't moved from center. I would love some advice.

Very helpful; thank you 🙏

Thank you for uploading and explaining it, thx toy you i have my own build ender 3v2 with line advance and input shaping! somehow the screen would not go to the mriscoc from gifthub, ending up downloading his files and folow your directions. For a non programming noob like me its not easy but you are the first one that made me understand. It saved me buying a ender 3v3se or ke now the acceleration is much better and printing acceptable fast ( still thing creality should have made it in stead of implementing it on thier new 3v3se )

Very good video, Thanks!

super helpful! Thanks

Hello, and thanks for this great how-to guide. Can you please advise about one other thing? I’d like to modify the formula(s) of the extruder stepper. Do you know which file I should edit? Thanks in advance

This is just a little cheatsheet for myself 0:29 Software download 1:05 Motherboardversion (the ONE information i never write down because i think "i will never ever need to do this again"!!!) 1:45 More Software 2:21 Download Marlin and organize files 5:30 Visual Studio Code Setup 6:06 Configuration Start / configuration.h 6:40 Motherboard 7:55 Stepper Driver 9:05 SAVE! and build a barebones FW if you want 10:35 Configure BL Touch 15:15 Babystepping / configuration_adv.h 16:10 LCD Screen

If you can show how to build the HEX version for CrealityPrinter/Cura FW Updater that would be awesome!

I have a couple Ender3 S1's and I need to recompile the firmware so Octoprint can fully work with my printer. The stock firmware does not allow Octoprint to react when filament runs out so it just continues printing. I have updated my mother board and screen software a couple times from Creality's website in the past but I see currently the Creality site is on Marlin 2.0.8 and I'd like to know if I recompile the 2.1.1 firmware from Github will my BLTouch and filament detector still work with 2.1.1. Not sure if those are controlled by Marlin alone or if Creality adds some of it's own code. Like the video by the way. Thank you for sharing it. It just re-enforces a few things I assumed but wasn't really sure about.

Thanks man. Easy to understand

Hi thank you very much for the video. Which configuration file should I use with my CR10S Pro (V2), because I can not find an example?. Thank you in advance

hey man great video, i cant find software related to the E3 Free runs board in the configurations bugfix file, is there a different board I'm should use?, thanks

Después de haber instalado marlin 2.1 en mi Ender 3 ¿qué ventajas me da ? ¿Ya puedo imprimir a altas velocidades o necesariamente debo activar el imput shaping?

Hello thanks for the good explenation, bud i get stuck, i have the creality cr10spro v2 with mainbord Creality 3D V2.4 and in visual studio there are a lot of creality mainbords but not mine, is there an solution for this, thx

Great video. Have you considered creating firmware for the Ender 3 V2 to work as an engraver/cutter? (Creality is selling a laser engraving/cutting kit.) I was wondering if the power supplied to the hotend is sufficient to power a 10W optical power laser like the one Creality sells. Greetings.

It works great, setup the line advance and the input shaping dailed in.. Now i am messing around in Cura for the settings, i guess the settings for the ender 3v3SE are close. boosted accelleration up to 2500 and infill speed to 180 and wallspeed to 80. Does anyone know some basic settings to use and keep the quality to use in cura? I cant seem to find any good gcode settings to put in except one draft one that makes me a 32 minute benchy. ( funny but not perfect )

I'm running a CR touch on an Ender 3. I have an upgraded board 4.2.7. I wanted to add more mesh points and upgraded Marlin to Marlin-bugfix-2.1.x I'm now having an issue with the Z probe being set not working. It is not adjusting at all. I tried saving and reloading as well as tuning while printing, and nothing seems to fix this. Do you have any suggestions on a fix?

Hi There, I do not have a probe and would like to get the machine to move to the 4 locations over the adjuster knobs. How could I set up marlin compiler so that I can do this and add a menu to my ENDER 3 PRO. Running 4.2.2 Firmware (upgraded to Marlin 2 already). Also I cannot see any writing on my micro processor on the main board.... but I must have fluked it with the selection of the chipset when I did the Marlin upload (cannot remember which one it was now) Thanks

How do you adjust the z-offset when you build this way? I don't see the menu item on my printer.

Hi, I'd love to know if the bl touch section of the video will be exactly the same if i were using a cr touch on my ender 3 pro.

I've got an ender 3 pro that I just upgraded to the 4.2.7 board hoping to run the sprite direct drive extruder. still have the original extruder on it now thought. followed you instructions and get 80 instances of "function call is not allowed in a constant expression c/C++(59) [ln x, col 5]. haven't found anything on the google and this is the first time trying to do this. any thoughts on what I screwed up?

so my letter on the sd slot was c and it matches hr 4998 but thats not an option. what do i do?

I didnt see anyone else with this problem and im experiencing it, when I try to home it says printer halted please reset, and when I try to manually move my motors that doesn't work. Any help would be appreciated

Question, if I have a .bin file is there a way to reverse engineer the firmware to see what settings are configured?

I am trying to walk me through your guide, but as soon as I try to hit compile I am getting a bunch of errors I have totally no clue of. I loaded Marlin as explained, loaded VSCode with all the updates like you did. Just the Configuration.h file turns red, Any Idea?

I've got a under 3 pearl. And I just installed V 42.2 and I am having a terrible time trying to program. And I was wondering if I could get a program from you on. Creality, firmware with the BL touch email to me or something like that. I am not very computer savvy. Say that's why I'm asking.

Will this work for a Ender 3 4.2.7 board with cr touch? And inside the configurations file in the examples for Ender 3, would I copy every file that is in there or just the configuration.h and configuration_adv.h? The other two files in the example Ender 3 folder are _Statusscreen.h and _Bootscreen.h. Like do I only need to make the changes you mad in your video? Or anything else? Also do you need to update a Ender 3 screen as well? Thanks

Need one for Ender 3 Board 4.2.7 CR Touch and Runout sensor please!

Amazing video. But my problem is my Ender 3 Pro has a GD32F303 chip. I can't seem to find the config for that chip ☹

okay so heres the problom im having the 2 files you moved are c++ files the one i have is c header files and after i edit the files i cant verfiy them and make it so that my printer can read it somone please help me

Stupid question. I have an Lk5 pro but would like to replace the motherboard and touchscreen with an ender 3 max motherboard/touchscreen. If I utilize Marlin, can I make this work? Please advise, and thank you.

I got the ender 3 max and on the sd card, there is a sticker that says T5 what do i do

Hi, sorry to bother you, it’s the first time I try to compile my own firmware and I’m practically a novice at using visual studio code. Each time I open the file I get an error on dev containers, the same error you get when you open the file. At 6:17 in the video. In addition I get a lot of errors on the define function and I don’t know how to fix anything of this. Obviously with this situation it gives me an error message when I try to compile. Can anybody help me?

Question, I got all the way through until you click build and it's not giving me the option for"RE" the only options i have are "RC"

What if my printer isn't listed in the config file list. I have a CR5 Pro Creality

after I install the bugfix2.1.x whenever i select gcode the watchdog triggers and restarts the printer

my sd card slot has both A and C written on it what's this mean?

So, after watching your video and learning more about Marlin, I took a look at my 4.2.2 board. On the SD slot it has a decal "T8" what stepper driver is this? FYI My machine is an Ender 3 Max Neo, the number on my chip set is GD32F303RET6.

tks brow, save my life. luv ya

Great vid, thank you. I am having a issue setting the Z offset. It will only allow me to go -5mm and that's it. I can go positive much more than this but I need the negative. Any idea why I am limited to this -5 offset?

Visual studio code is where my problems start. Constant install pop ups when im already installed and using it. Literally every 10 seconds and it messes with the editing as it stops the user connection while its up. Its driving me insane. Then theres in program config problems i have no clue how to sort out. Trouble is, Reinstall it and all the troubles come back with the fresh install. I admit its user error, Im a thick lorry driver not a pc wiz. Id love to get this sorted out as both my E5+'s are down and making depression rather than prints.

Thank you for your help! My motherboard chip has a T5 on it. Where can I find what steppers to use in the config file? One more question, I did the dual z upgrade and not sure what motor I put on it. Do you think it matters? Thank you again for making this video.

great tutorial and remember, you have a very clever face!

Great video. Slow enough that I can follow fairly well. However, looking at the motherboard 4.2.2, it doesn't show a letter on the USB. How do I know which driver number to use?

​ @PrintPractical I'm crunching along trying to add Runout. I already added silent mobo and CR touch with Ender3Marlin2.0.6HW4.2.7BLTouch.bin. I have 4.2.7 mobo, CR touch, Runout, on Ender 3 chassis. Waiting to hear back from Creality but also trying to build myself.

great video thank you so much. i have uploaded the firmware to my ender pro 4.2.7 board, am just getting a weird error on the printer saying eeprom version. have double checked serial numbers seem to be correct on the firmware. any tips would be really appriceated

Also i have a gd cpu/mcu not stm i dont see that in the config😢

8:14 mine sc card says GD what's meaning this?

Will this work for the V3 SE?

good morning...my printer is an ender 5 pro...with the stock firmware which was 1.0.1 with a 4.2.2 board...i updated the firmware to 2.1.2... with the stock firmware after a print the hotend would go back to the right rear...after i updated at the end of the print the hot end goes to the left front...what setting do i have to change fot it to go back to the left rear...thanks for any help

Hi Thanks for the upload, my 4.2.7 has TMC 2225 drivers. There is no option in the config for these drivers. Is it safe to use the 2208 as it is the same driver but in a different shaped chip? Thank you again from a new sub.

My SD card reader has a sticker that says "T5" on it?! any suggestions?

I have an ender S1 pro and there's no letter on the sd-card, there's a sticker with "T8" on it. So what stepper driver would that be?

My sdcard slot has gd on it. What now?

GOOD MORNING...i have another issue...last night i was at 76% of a 60 hour print....we had a storm come thru and lost power...i have marlin 4.2.2 on the ender5 pro...i looked thru everything and could not find a resume print after the power finally came back on.. i was so upset cause i lost my print

so no luck for 4.2.7 boards i see cause theres only config for 4.2.2

after completing everything my printer will not do anything now. im not sure where i went wrong its just booting to a black screen

I found a M4 sticker on my v4.2.2 board. Anyone can tell me what stepper driver I have?

Really liked your video. During the technical part I find your video overlay box very distracting. Otherwise really informative.

I have an ender 3 pro with bltouch with a bigtreetech 3.0 v3 and I followed all the steps considering the different config files and board and all but all I get no matter what setting I change is just a blank screen. Need help :')

Screen updated (went to 100%) but goes black. Then I turn the printer off/on but it's always black :(

Why does no one explain where they get that mini search tab in their videos.

you keep referring to links below but there are no links, also how to change build plate size to 300x300 and print head to high temp and to high flow

Was hyped for the landscape opion but i opened my screen up and realized it is DACAI = no landscape option :c

I love you so much (No homo i aint gay like that). I spent like 50 hours trying to do this on my own, and I could not find a good tutorial on this. But then I found this one.

nice, now my printer stops whiel homing and does not print anymore

I have windows 8.1 since the newest upgrade on visual studio. How do I get the old visual studio version back? Also. If I'm using insanity firmware on my ender 5 plus, do I still install marlin firmware?

Come on man, buy that winrar!

I hope it will go yet...

sir, your skin looks like marble 😲

totally not easy. i have the gd cpu/mcu took ages to get vscode to complete install now only compiler errors. that will teach me to buy a famous brand. i alwqays thought I got my self in trouble buying old/cheapest obscure things. but branded things have worse support. sry not complaining about youre vid which is exellent just upset with creality supplying and updated firmware for bl touch with the extrude running backwards now (almost a year ago) and every thing else going wrong. all week.
