Basic Information: Printer Model: Voron 2.4 MCU / Printerboard: Fysetc Spider klippy.log klippy.log (5.1 MB) Alright so I just tore down my V2.4 with around 5000 hours on it and did the R2 upgrade, as well as CANBus. In terms of firmware, I just ran the original instance of Klipper and Mainsa…

Problem solved guys - I went back and checked my canbus-ebb36.cfg folder and there was till some heater_extruder PID control information uncommented that Klipper was not able to overwrite with the SAVE_CONFIG function.

Hello @Tooks ! Can you upload the printer.cfg please?

Hey @EddyMI3D , thanks for the quick reply! Sure, I’ll attached that here: printer.cfg (19.2 KB) I can confirm, bed mesh ISN’T broken, you’ll see that it saved to the correct area, but I just tried to PID autotune the hotend again and no dice.

Un-remark these lines in your [extruder] section and try again: #control: pid #pid_kp: 21.788 #pid_ki: 2.046 #pid_kd: 58.012

Same issue unfortunately, very weird

No luck unfortunately, there are no other instances in of PID control for the hotend, and also no luck if I try to just paste new values at the very bottom in the SAVE_CONFIG section

Please post your entire cfg files

The issue is if there are two tune settings for the same heater, Klipper reads them from the top of the .cfg file until it finds the first set commented or not commented and ignores the rest for the same heater. I would assume Klipper builds one cfg file in its memory starting with the printer.cfg.…

Thanks for your input @NAPCAL ! But there is no reason to dig out a solved thread that is over one year old.
