Ender 3 S1 Pro stops mid print

Basic Information:

Printer Model: Ender 3 S1 Pro
MCU / Printerboard: STM32F401XC
klippy.log (1.7 MB)
Specifically, The error(s) on 11/24/2022

In the middle of a 14-hour print, the print stops. When I look at the screen of the sonic pad it states “Can not update MCU mcu config as it is shutdown”. When I go to the last command prior to shutdown it states "{“code”:“key61, “msg”:“Unknown command:M486”, “values”: [“M486”]}”. Any help is greatly appreciated.

Hello @ez8853 !

M468 is meant to cancel an object.


Usually not supported by Klipper.

You may check your slicer and/or Klipper setup if something is inserting this command into your print.

Thanks. I turned off “Label Objects” in Prusa slicer and seeing if that will fix the issue. I will update tomorrow. See below:


Turning “Label objects” off solved my problem. The print finished.
