I have never seen anyone make something so simple as complicated as this, you go so fast that I have had to skip back about 30 times and I haven't even downloaded Marlin yet.

Superb info as always. Looking forward to your 'from scratch' video, it may show me something I missed as I just finished upgrading my CR-10 S4 from scratch to Marlin 1.1.9. Loads of new features and fixes.

Thanks for making this Thomas, looking forward to the part where you show us Configuration options separately!

Appreciate the video! I had just bought the 1.1.5 silent board for my Ender 3 Pro and accidentally bought one with the Ender 5 firmware. Your video was the easiest to understand and simplest solution for me since the board already had a bootloader. I just downloaded the source code from Creality, followed the tutorial and was immediately able to start printing. Thank you!

Nice video! Especially like the part about showing how to install the Sanguino option to the Boards Manager and the u8glib. I had just used the TH3D unified software to run Arduino and then pointed that to the Marlin 1.1.x folder to get around it before seeing this video. The TH3D is a good option for those wanting a simpler option, but I like to know what each setting does (or at least the main ones). Looking forward to your video where you go through all the options in Marlin.

Hi Tom, Kudos for a great tut. It makes my day seeing how open source and community based projects' work, reaches the level of world class commercial setups (there effectiveness, efficiency and reliability are second to none) Marlin and Arduino are 2 great software and hardware examples (I know there are many others out there); great times.

Thank you for instructions! I did the upgrade for my Creality Ender-4. There are some differences comparing to Ender-3: the processor is ATmega2650 and its support is included to Arduino AVR Boards by default, so no need to set up Sanguino board and steps associated with setting up the board may be skipped (I set it up first and then just removed:-) Also, I made some more configuration 'cause I have extra gears attached to the printer: auto-leveling and filament sensor. So, went through the config files and un-commented lines to activate corresponding features. Configs are well commented and it is easy to find proper lines responsible for certain features...

Hey Thomas, I got a new motherboard for my Ender 3 and now I was updating the firmware but in the end when I was uploading it says that an error occurred while uploading the sketch

Thanks for the step by step. Worked great. I could not have done it with your instructions keep up the good work. Needed to upgrade the firmware to eliminate the extruder stopping with the quiet main board when using Simplify 3D

Will you lose the Ender-3's ability to resume prints after a power outage by upgrading Marlin following these steps?

Hey come on Tom I wanna got to Hollyday`s and always remember and thinking of flash my board with marlin firmware. And now your coming up with this video. Thanks for al the great vids out there and your share of all that knowleage. Schöne grüsse aus München ;)

when i try to do this i get an error that you didnt talk about

Just some additional info: A third issue you might run into uploading new firmware is if your printer uses the MKS TFT family of display screens (ie: JGAurora A5 & A3S). These 'intelligent' controller screens constantly communicate with the mainboard and have been shown to interfere and even corrupt the upload of firmware. So its recommended that you disconnect the MKS TFT board from the mainboard before uploading new firmware. Also, if you are uploaded a different version of the firmware (not just newer), you MUST reset EEPROM to factory defaults or it Will Indeed be all wrong and very strange things will occur when printing (homing the wrong direction, over-temperature faults, wrong acceleration/movement settings, etc) Thanks for the great video!

Awesome video at just the right time. Was going to spend the evening configuring newest marlin, to upgrade my cr-10. Just got a lot easier.

Thomas, great job. After downloading the files and updating the boards manager, using the correct processor and adding the custom library it compiled on first try.

this works! after following other vids online, this is the only vid that works for my Ender 3. thank you soooo much!

Thanks for sharing Tom. very informative as always!

How do you convert an old configuration to the new Marlin 2.0 when there is no manufacturers version available. I only can get hold of Marlin 1.0.4 for my Geetech and i'm havin g problems, I would like to upgrade to either 1.1.9 or 2.0. but don;y know how Thanks

Thanks Thomas; as always clear, engaging and useful. Worked great for me.

Thanks for the vid. It was a very helpful walkthru to getting the correct versions of everything and getting the Arduino IDE all set up and able to compile the project. Thanks to your vid I was able to confidently get Marlin compiled and ready to load on my ENder 3 pro. I lost my USBASP board during a move, and so I'm waiting for a new one to talk to my board. (I prefer this to using my UNO which I also can't find, LOL. It's been a few years since I did a lot of microcontroller and Arduino work.) But your video was a confidence builder.

Thanks Thomas! I had to get the U8Glib 1.1.7 somewhere else, but you got me through it!

I like the way you pronounced "Zachariah." I've never heard anyone say it like that.

As I was trying to upload the firmware to my Ender 3, I was given the error "avrdude: stk500_getsync() attempt 1 of 10: not in sync: resp=0x65 avrdude: stk500_getsync() attempt 2 of 10: not in sync: resp=0x63 avrdude: stk500_getsync() attempt 3 of 10: not in sync: resp=0x68 avrdude: stk500_getsync() attempt 4 of 10: not in sync: resp=0x6f avrdude: stk500_getsync() attempt 5 of 10: not in sync: resp=0x3a avrdude: stk500_getsync() attempt 6 of 10: not in sync: resp=0x54 avrdude: stk500_getsync() attempt 7 of 10: not in sync: resp=0x46 avrdude: stk500_getsync() attempt 8 of 10: not in sync: resp=0x20 avrdude: stk500_getsync() attempt 9 of 10: not in sync: resp=0x69 avrdude: stk500_getsync() attempt 10 of 10: not in sync: resp=0x6e An error occurred while uploading the sketch " Does anyone know how to fix this?

As others have said, the work you put into this is greatly appreciated, but for those of us who aren't technically-minded, it's like falling down a very deep rabbit hole with pointy bits along the way. But that's a heck of a shirt, Tom.

It wasn't really easy, but you walked me through most of the hard stuff. I still had two errors (very similar) where they put something in comments AFTER the command and apparently my board wanted the comments BEFORE the command on a separate line. Fixed both of those errors and everything else went smooth as butter.

Great info Tom!! I do have one question. I build a dolly back when you did that build series. Does this work for upgrading the firmware on it as well or will I have alot to fix since its not a "production" kit??

Thanks very much Tom! How can we update the firmware if we do not have any support or file from the manufacturer? How do we only have the firmware loaded on the Mega board and no other data? How do we adjust the values for the different types of extruders, rods of the Z axis, etc? Thanks for your kind support.

Thanks, just followed your instructions for the Ender 1.1.5 board for an ender 5. Worked fine once I found ender5 config.h files and I had to use 1.18 of the U8glib but it compiled ok and I guess the board had the bootloader as it loaded fine. Now to put the board in the printer and test.

Thanks for the excellent info as always, do you have some info on changing the code for the printer knowing where the center of your bed is? My Ender 3 is 4mm left and 11mm back from what the slicer thinks is center.

hi Tom, thanks for the video! I followed these instructions but when i get to the point where i want to burn my bootloader (with the USBTinyISP) I get the error below, can you help? avrdude: verification error, first mismatch at byte 0x1fc00 0xff != 0x1f avrdude: verification error; content mismatch Error while burning bootloader. thanks, Mike

Awesome the previous video was a bit old, much appreciated

Great video, Tom. I'm pretty much a newbie and not real computer smart, but I followed your directions step by step and successfully replaced the original Ender 3 firmware with the current version of Marlin. It added some nice functionality (like being able to move the Z-axis up and down from the LCD screen) and I'm enjoying it a lot. Thanks!

Hey Thomas, great video as usual. I own a Creality CP-01 and was curious ho to update to Marlin 2.0? There is no files inside Marlin for CP-01. Please help

Hello Thomas I have the following error, for compiling it was ok however I cant upload it onto the board, any idea? Sketch uses 122088 bytes (93%) of program storage space. Maximum is 130048 bytes.

Thanks for sharing this information. I need to enable the Thermal runaway protection on my printer. By the way, nice shirt :)

Great video Tom. Thanks for the insight.

Thomas, you're the best. Thanks for this video

@Thomas Sanladerer HUGE THANK YOU! This made me finally reflash Marlin on my CR10s. Was thinking about it for months, but was too afraid from complexity. Done it, and it worked.

Help Please. my printer doesnt have an example config. would it be wise to just copy my old config files over OR is it better to take a similar example config and just change the values?

thank you ... is it possible to resume print with and other printer , and which one ? ... all .... thank you your video is clearly ....

You said it will apply to any future 1.1.x version. But the developers have stated there won't be any more of those 🤔🤔🤔🤔. Regardless I can personally attest to 2.0.x being the exact same process.

Hello. İ have i3 steel marlin 1.9 running printer. İ will update to marlin 2.0 for power loss resume spec. Question is do i need to make step adjustment for step drivers?

Hello teacher my marilyn does not show menus from the lcd if the lcd row is active only the blue light on the screen if it is active in the row loaded at u8glip

Hi Thomas, Thanks bud for the video, realy helpful, Now i have the new merlin firmware on my ender 3 (v1.1.5 board) thanks again

Hey buddy great video as always :) I have a question how hard would it be for a Cr10 s4 with a touch screen

Hello, tell me please, if you know, there is a need to raise the upper temperature limit for my 3d printer, how to do it correctly in marlin?

a couple things that I found need to be changed in config.h are the minimum y set to -8 and set the bed to 232 mm. now you will print more in line with the center of the bed and take advantage of the larger build surface

Great video. But have a problem with my printer . It's a sainsmart 300 . Out of nowhere something when wrong . It's like the print head is lost . What ever I print it starts ok for the first 2 or 3 lines then it goes sync and wondering all over the print plate . I dont know if it's the firmware or a hardware problem all the step motor are good . . Can you help . Can I send you a video of what it's doing.

What about printers that aren’t included in the example machines folder?

I thought you make a Summer Brake or something like that. ;) Nice to have you back in the Game. 👍 I will try that Upgrade with my Anycubic i3 Mega. (if there is any Update avaible)

Wait so I need extra hardware to update my Ender 3? I will have to wait until I get the part then

Hi Thomas. I've downloaded 1.1.9 and successfully loaded into machine (CR-10S), previous version - 1.1.8 which works just fine on my printer. The only thing I want to add to my 1.1.8 is the S-Curve option and that was a reason why I went for "upgrade". Everything seems working just... "tiny problem" :-) - failing the homing procedure. X and Y homes fine but Z... it lovers the gantry on some 10-12 mm and stops in mid air (far away from end stop, like it find the ZERO), try again - same, and after couple of "homings" just halts the printer with message "Homing failed, printer halted" - restart. and the same whatever I've tried to do. any ideas? Thanks

Hi Tom, thank you very much for this video, it saves me money to buy a new board!

Important before uploading the firmware: Disconnect all other serial connections to the printer. Close Simplify3d or Pronterface and disonnect the TFT32 (in case you have one). If either of these are connected to the board when uploading the firmware you will get a generic error message. That took me wayyy too long to find out.

Holy balls, this is too much for me to even try right now.

I get an error about old configuration.h file. how should i fix that?

I just updated mine, but now the new default FW speeds for homing Z, X and Y on my ender 3 has doubled, including print speeds, and i don't want it that fast.

Lot to keep up with when you're a noob. Saved this video because I'm going to watch it 100000000 times till it all clicks. I got issues just like loading firmware for my bl touch I just got for my ender 3. Great video btw and I will be trying to catch up.

Hi. I ended with a blue screen with no characters on it but uploaded complete. What should I do?

Thanks, Thomas, I was able to burn bootloader and Marlin firmware on my Ender 3.

Super video, tnx to this tutorial my 'bricked' ender 3 is working again.

I have a Sain Smart Ender 3. should this be the same? is there anything that may be different or that I need to worry about?

Thanks for the video. i did get a issue with my memory. not enough with my ender 5 pro. any suggestions?

You did forget the M503 before uploading your firmware to get a copy of your old EEPROM settings if you fiddled with any.

Do I need any other hardware such as a bootloader or sosmething? Becuase mine is getting errors uplaoding at the last second.

So just to confirm, we cannot use this video if we have an ender 3 until you upload a new video for ender 3?

Hi . I have problem in bourd 3d printer . And want some help . Board name is ( one+ v2.2 ) . When upload marlin . Lcd not work . It just light

how do i updage the firmware on a ctc-A10 (cr10s clone) i have no idea what the board and processor are and im trying to do the th3d version but im happy to do the marlin version, i just want mesh leveling enabled

Great work, Thomas!

Hi butty.Can I follow this step without having to buy arduino etc. Just use my usb to my pc. I have a board that shows 1.1.3 on the board. Appreciate a reply.

i have a crealifty cr10 v2 with a blank screen need to reinstall the firmware but will not install I am using x loader not working I need help

Hi im using a longer lk5 pro... is the procedure that different? And they are up to 2.0 now

Hi ! I also have an Ender 3, and yet my pc didn't recognize or even detect my 3D printer when I connect it by USB, what can I do ? (also I can't do circles, rounds with it so if someone as an idea to help me with that too (I've already try the belt))

hi tom can i use this method on my anet a3 .witch has a anet board in it .or do i have to do a boot loader thing cheers mate

can you run us through a 2021 setup git hub has changed there file location and having some problems finding the files i need to download

I have 2 Delta minis that I haven't ever gotten to work correctly, is this version more friendly for deltas than versions past?

Does the Marlin Firmware support the power loss function on my ender 3?

Extremely helpful material even in 2021. Five five bro ;)

I ran it again and it worked. Did you say that I will need another board to flash the board for an Ender 3?

very useful, thanks Thomas! I'll see if I can update my Geeetech A20T

I have a weird problem. My Ender 3 + Bltouch seems to be higher in the center of the bed. So after it centers itself, I set Z to zero (with z offset) , disable the steppers just to make sure each corner is leveled properly. After leveling each one with a piece of paper, and setting it back to auto home. The adjustments I just made are back to where they were as incorrect. Any suggestions??

Can I install Marlin 2 In my ender 3 with a "Elegoo board one r3 "?!

Hello Thomas, this is the error when I try to upload the Marlin: stk500_getsync() attempt 1 of 10: not in sync: resp=0x65 Can you help me? Thanks

When i upload Full graphic discount lcd file.....it says "File name or path too long" .....what to do ??

After flashing vanilla Marlin I don't have anymore the percent of work done displayed. Is there any solution to that?

I just upgraded my ender 3 with the TH3D firmware and getting the bootloader working was the hardest part.

Hey I have wanhao I3 robo 3D and the king original prusa I3 mark 3. What should I do to make my wanhao and robo 3D can produce the same result like original prusa. Shold I change the board and firm ware?. What bord and which firm ware should I use. Please let me know.

What about printers with a touch screen lcd? Are those not open source? Example would be the Snapmaker printer that says they will be open source eventually but would the firmware update not work great with the fancy touch screen?

Bro very nice video very nice absolutely amazing just wanted to confirm one thing that i have ender 3 pro with 4.2.2 board does that need a bootloader or will it just work the way you did thankyou so much waiting for reply

Hey Tom, can you make a video on how to set up ABL with Marlin?

I tried to verify my build on the Anet A6 but it failed because it's 40 bytes too big with the BL Touch sensor enabled. Had to enable Linear auto bed leveling to reduce the size. Thanks!

Beautiful relevant info! Thanks!

Ive been trying to update the firmware on my Anycubic Chiron, but it doesn't seem like any software on my laptop can acknowledge that the printer is connected via USB. Cura does not see it, nor does the Arduino software (which I'm new too).

i have an arduino uno, can i use it to flash my firmware?

I flashed 1.1.9 last week on my older RepRap with a mega / ramps combo. Never had any problems with the older versions and my endstops but when I flashed 1.1.9 I couldn't get it to G28 without running the command like 3 times. Eventually had to turn on the ENDSTOP_NOISE_FILTER in config. I have some .1uf ceramic caps on the way to attach to the endstops so hopefully I can turn that feature off again.

So to clarify do all ender 3's not have a bootloader? Being new at this im not exactly sure wht that even is

I have a KreateIt KR-10S which is a CR-10S clone how can I tell what board, LCD, and Processor it has? Thanks

wheres this video of him showing us how to do the next step on the ender 3

Very good tutorial, fantastic! Congratulations ;)

Looking forward to the next video, because I want to upgrade my wanhao duplicator i3 to marlin.
