MCU 'mcu' shutdown: Invalid oid type

Printer Model: Tronxy X5SA PRO

klippy (6).log (5.7 MB)

Hey guys! I am having issues with one of my printers. After ~20 minutes of printing it just freezes saying:
image

I checked the log but I have no idea what to look at.

Things I’ve already done:

  • replaced the mainboard and the raspberry pi
  • changed power supply on both, printer and raspberry
  • rewire electronics and propper ground them
  • changed multiple USB cables

You are flooding Klipper with unknown and strange commands.

Unknown command:"M566"
Invalid M204 command "M204 P2200"

Find their source and fix them and repost a new log if there error reoccurs.

I have the same messages on the other printers but I simply filter them and everything works perfectly fine. The only issue is on this printer.

Personally, I will not dig any deeper into this issue as long as these errors are in there. Get the obvious done first and then see where we stand.
