this is a repost from Klipper install Anycubic kobra 2 - #119 by TrainComputer

hi, new to 3d printing and have a kobra 2, I’ve had issues with very unlevel bed issues so I thought ab klipper. started researching and found this to be the most prominent solution but I don’t have a arduino, just a esp32

so i thought up a neat solution to my problem, which was to install klipper on linux, specifically i was gonna install it on a modded Nintendo switch that had switchroot/ubuntu and turns out, it kind of works.

i installed the custom firmware onto the printer from the switch, i used kiauh to setup the switch with mainsail and klipper.

the custom firmware doesn’t seem to want to install, does some low tone beeps, 1234 … 1234 and just stuck at the anycubic screen, using official firmware works fine and brings it back to being able to work. unsure the behavior I’m supposed to get, if it did supposedly work on the printers part it doesn’t on mine tho it may be simply because the config for the USB connection isn’t setup to my specific situation.

I followed crororo’s guide as it seemed to be more up to date, the issue seems to be with the USB connection (looked at logs, No such file or directory: ‘/dev/serial/by-id/’)

mcu 'mcu': Unable to open serial port: [Errno 2] could not open port /dev/serial/by-id/<your-mcu-id>: [Errno 2] No such file or directory: '/dev/serial/by-id/<your-mcu-id>'

This means either:

Since you are

  • using a non standard Linux / Host (Nintendo switch)
  • you modified the firmware
  • the support for the Kobra 2 series is not confirmed
  • Anycubic has unknown modifications to Klipper
  • Anycubic has not released the sources of their modifications

you are pretty much on your own.

ended up using a laptop, it worked as I was able to find the file usbtty0 unlike the switch, only issues right now is just with trying to fix my bed level issue, it used to be at a 2 mm dif but I got it down to sub 1mm but it still ruins the first layer with z offset so to combat it further I’m setting more probe points for the mesh and tightening/ loosening of the screws on the bed
