Describe your issue:

Hello, I’m new here so please forgive any posting errors.

My question is about the M420 gcode command.

Specifically, is this a valid Klipper code? I have seen it added to my slicer’s machine settings in some machines and not others. Is it necessary or will it overwrite the bed mesh the machine performs prior to every print?

While on the gcode subject, is there a reference available that lists all pertinent Klipper-friendly gcode commands?

Hello @Bruce1 !

As for G-Codes - Klipper documentation and G-code - RepRap, M420 is not a valid Klipper gcode command.
