FAQ begin:

Q: Is there Klipper available for these Printers?

A: Some Yes and some No, the community on Klipper board is very active and i think we will got these Function in the near Future.

Q: Why theres no Klipper for PRO/PLUS/MAX?

A: The Motherboard is a new generation of Trigorilla Board (Trigorilla_Spe_A_V1.0.0) These didn´t have a normal MCU like STM32Fxx or GD32Fxx. They put on an Allwinner Arm CPU (R582-S3) This CPU controls the whole Printer. So it must be reverse engeneered before they can compile a Klipper Version for these Printers.

Q: I got error Messages "Hotend/Hotbed NTC abnormal please check it an wiring/ Please Restart"

1- When you have NTC errors Like "NTC Heatbed or Nozzle abnormal. Check first if wiring is correct. Now check with a multimeter in Ohm´s Mode if the Values are like the Values in the Chart.

2- Sometimes after many times the Hotend gets Hot and Cold it can be that the NTC probe got a little bit loose. Check if the Screw is tight and the NTC is not loose.

Q: How can i configure or Modify my Printer.cfg?

ATTENTION! IF YOU TRY THIS YOU DO THIS UNDER YOUR OWN RISK! I KNOW 2 PEOPLE THAT BRICKED THERE PRINTERS!!!

Thanks for mentioning my K2Pro infosite :)

I'm currently working on an infosite about the K2Neo as well, but I still need a reliable user who is willing to take specific pictures of the K2Neo as I don't own that machine.
So for now the content in there does already somewhat fit (due to the same construction as the Kobra Neo and the same printhead as the K2), but you won't see K2Neo-specific pics etc.

Once there are 100% working Klipper solutions and reliable printer.cfg available for both the K2Neo and the K2Pro/Plus/Max, I'll mention them in the specific Klipper fw chapter as well.

As for Klipper for the regular K2, one can also have a look at this post (so one doesn't have to go through the whole Klipper discourse thread): https://www.reddit.com/r/anycubic/comments/16p4v0g/klipper_for_the_anycubic_kobra_2/

As for the problem with the hotbed/hotend temp error messages: one can find detailed instructions about the problem itself, how to check the different causes and how to fix it at my infosites as well btw.. ;)

Of the Kobra 2 Plus you mean? Sure, that would be nice, then I'd make a K2Plus infosite as well. There was a user who offered that as well, but he never came around with pics..
Please reach out via chat or email (address is in the footer of each page of the infosites) then so we can go into detail about it.. ;)

Same for the Kobra 2 Max btw - just in case anybody comes across this.. ;)

Thanks for your offer, much appreciated! :)
Another kind user also offered the same tho, so I'll wait and see if he provides me the necessary pics. If he won't do so, I'd reach out to you again then. If it's ok for you, I'd just reach out via chat right now really quick to have you in my chat list.

Unlock the kobra 2 pro firmware please, I need to tinker with it. Or please release a kobra 2 pro model with open source klipper. yeah,

I know I can get a kobra 2 and add klipper to it myself.

I been thinkin.

I just bought a Kobra 2 Max. It was a hard decision between the Neptune 4 Max and the Kobra 2 Max but the hardware seemed slightly better with the K2Max despite the hardware issue.

How hard would it be to port the K2Max to work with a different motherboard like the BigTree Octopus or the EZ Pro?

I mean, it's a bedslinger. X,Y,Z axes. Pretty standard. Wouldn't it be just a matter of tweaking the firmware on those boards to match.

Or do we need a hardware specific blob from the encrypted firmware?

Im Not so professionell into this but i think it isnt to hard to Change the Mobo and config it with Klipper. I thought about an Manta M5P Board that should be small enough. The only Thing is that you have to Change many of the Connectors.

Hey brother, do you know if Kobra 2 Max uses Marlin or Klipper g code flavor?

Help! Kobra 2 Pro I've used 1_download_cfg.gcode and 2_upload_cfg.gcode to change a bit printer.cfg and now it's not loading- stucked at anycubic loading logo. Tried to update firmware with update.swu on usb but no luck. Appreciate any help!

Opening-Winter-8250

2mo

Get a clean USB Drive and copy the FW 2.1.0 on it. put it to USB with Cam logo on it restart printer and wait a little time. I cant reproduce the problem but can you send me DM with your printer.cfg file that corrupted your FW?

Prestigious_Egg_4194

2mo

Thanks for your answer. It seems It's not working to upload a new firmware (tried many versions, different usb, different ports) . The printer stucked on the loading logo. Anycubics support answered I can update manually and provided a link to 2.3.6. Not working as well. DM was sent with the printer.cfg caused the issue. Thanks again.

:( I did all by instruction, but see: Printer is not ready The klippy host software is attempting to connect. Please retry in a few moments.
What I missed?

That´s wrong i put in a new link they´ve got klipper working!

Im had read thread with klipper reverse and have some skepticism about it. Because if shitcubics want - they can easy block this in new official firmware and all work would be lost.

Also - there is just to much work what probably need to do for this, without any warranty to success. It is much easy to just buy and integrate OrangePI + any STM board.

New to printing and somehow nuked the SD card that came with the printer. Does someone have a copy of the "Suggested parameters for PLA-V1.0.ini" for the Kobra 2 Neo they could provide?

Just get it from AC's support page (make sure to choose the correct printer model tho!): https://www.anycubic.com/pages/firmware-software
