Ender3 V2/S1 Professional Firmware 20220419 - APRIL2022 release

[mriscoc]

Universal APRIL 2022 Edition

This firmware is based on Marlin, has been optimized and has enhancements for the Creality Ender 3 V2/S1 printer. This is an universal firmware that can be used in both RET6 and RCT6 SoC chips that have 256k or 512k Flash memory.

CAUTION! It is confirmed that Creality is selling some S1 with a STM32F4 chips, The 20220419 firmware version is incompatible with this SoC, only boards with STM32F1xx are supported.

Versions

• Ender 3v2 Manual Mesh: if you have the Ender 3v2 near to stock then use this version.
• Ender 3v2 BLTouch: use this version if you installed a CR/3D/BLTouch level sensor in the Ender 3v2.
• Ender 3S1: use this version if you have an Ender 3S1 printer

UBL versions

Binaries with UBL in their filename have support for Marlin Unified Bed Leveling, this system is similar to the bilinear leveling but with a few extra features to provide users with more control. There are multiple guides on the web about UBL, we recommend reading about it before using this new leveling system.

• https://hackaday.com/2022/01/14/3d-printering-getting-started-with-universal-bed-leveling/

The binary files of this release are up to date and you can download them from the assets at the bottom of this page. To know if you have the last release go to the info page in the display of your printer and compare the release build date with the name of the binary file. The filename follows the convention:

Ender3v2-422-ManualMesh-YYYYMMDD.bin

Where YYYYMMDD indicates the date of the build. 422 refers to the mainboard version 4.2.2, and 427 is for the 4.2.7 mainboard version, if you got a 4.3.1 board use the 422 version.

Precompiled firmware

This discussion was created from the release Ender3 V2/S1 Professional Firmware 20220419 - APRIL2022 release.

[leberschnitzel]

just as fyi: Still doesn't work with S1 Pro

[mriscoc]

Sorry but maybe this firmware will never work with the S1 pro because of the touch screen.

[leberschnitzel]

oh yeah, not meant to push for that, but I'll keep trying to find a way ^^

[Dooti-2]

Just flashed -- perfect. Love the sub-menu shortcuts....you are the MAN! Just donated $10 to support the cause as well. Keep it up hermano.

[Dooti-2]

• okay..... @mriscoc when my bed hits 39 degrees the machine flashes power and restarts....so odd. Any suggestions?

• its the 427 board....E3v2

• w/ CRTOUCH

• (i plugged in BLTOUCH, still does it.)

• I reverted back to 20220330 release (or there about) and it's doing it too...

Should I try the February release? That was the last stable one I was running.

[mriscoc]

Thank you for your donation. Please try to do a "Restore defaults" and "Store settings" to clear old EEPROM values. But, seems to be a possible hardware failure.

[Dooti-2]

Yeah it is hardware...I have tried everything and ALL adjustments made via the screen work EXCEPT for when I begin to heat either the hot end or the bed. Checked all cables....even replaced thermistors for good measure. same thing. think its the board unfortunately.

Maybe it is a power source failure, when the bed starts to heat, it consumes more energy.

[RubeNL1992]

At first it takes a while to start printing, because preheating will fluctuate to much around the desired temperature.
As soon as its starts printing it looks like its stops heating and cant print anymore.

[mriscoc]

There is not that behavior in our tests, check your termistor. Do a PID, also, check your silicone jacket of the heater block

[RubeNL1992]

Termistor fits well! Did a PID aswell but without succes. Just went back to version 20220330 and the problem is solved again.

[azsundevil02]

Having a new error on my s1 F4 board. Finished a 3 day print. Went to do a mesh (9x9) and it just keeps looping through the auto bed level process. When it finishes it just re homes and starts again. Doesn't give me the results screen. Then it started saying there amwas a probe error shut down machine. Have done that - but I can't seem to get a new abl to run and can't print.

[azsundevil02]

After I shut off the machine and turned it back on all settings had been wiped. Z offset was set to zero and there was no stored mesh in settings to load. Not sure if I read that the z offset being wiped was a known issue when just rebooting the machine.

[azsundevil02]

Hmmm I still had hs mode on or it turned itself back on. Will try turning that off and trying again. Do the settings get wiped every time you turn off the machine? I thought it was just when you flash the firmware. Maybe I misunderstood. Also - when printing - my double lines turn blue if I activate leveling...am I supposed to have red at all or just the blue / white?

[mriscoc]

F4 is in experimental stage and has known issues #125

[azsundevil02]

Awesome - thank you. I don't know why I didn't see that one when I was scrolling thru the list.

[vpereiradn]

Thank you so much for the FW I'm using it now, I hit 220x220x250
and the e-steps 424.9 but it is still off the edge and the size of the bed is out coming out the automatic alignment of the CRtouch..

you have the values for this FW right!!

I really appreciate if you send me!!

Sorry, I can't understand your problem, if you changed your extruder/fan duct then you must change the physical dimensions / offsets according to your specific setup. I don't have those parameters, maybe other users with the same changes could help you. I recommend posting that requirement in our Facebook for V2: https://www.facebook.com/groups/ender3v2firmware

[killer-vp]

então to lutando com isso a mais de uma semana nao sei mais o que fazer!!

[rombourg]

Miguel. Thanks for the good work that you shared. I have the S1 . Could you provide the source code specific for the S1.
Thanks Ron

[azsundevil02]

https://github.com/mriscoc/Ender3V2S1/releases/tag/20220419

Scroll down to the bottom and look for the version for S1

[rombourg]

Thanks - I updated my S1 with the Sprite Extruder Pro. Updated firmware by changing temp sensor to # 13 and Max temp to 300. Compiled and flashed . Appears to be working.

[mriscoc]

https://github.com/mriscoc/Special_Configurations here are configuration files for the type 13 thermistor.
and some binaries here: https://github.com/mriscoc/Special_Configurations/releases

ender 3 v2 skr mini e3 v3 y axis wont home

[mriscoc]

Check your wiring
For referece: #131

[EXCISIONMODZ]

its correct
it worked on your last version

[CaptJocco]

Hello, is there a way to configure this to work with the Ender 3 Pro and it's standard LCD screen. I have the 4.2.7 board, BLTouch and Sprite Extruder Pro, and this firmware seems to have all of the features I'm looking for, except that I have the Ender 3 Pro. I'm still relatively new to 3D printing, I'm learning quickly but have a long way to go. I just tried compiling my own firmware but I guess I still have more to learn because I got a bunch of errors when compiling and I don't know how to fix them. Any help would be greatly appreciated. Thanks

[mriscoc]

Hi, the current requirements are published in the Wiki. There is no support for monochrome LCD screens.

[CaptJocco]

Thank you for the reply. I just purchased the upgraded color touch screen (it arrives later today from Amazon). Once I install that, your firmware should work for me at that point, correct? I really hope so, lol, as I'm starting to get to my wits end with figuring this out myself.

Thanks again
