How to change a g-code command?

[Yihang]

when I define gcode_macro M106, it said M106 already registered, how to change Klipper configuration?

Hi @Yihang,

Since you didn’t upload your klippy.log, my best guess is you defined the macro something like this:

[gcode_macro M106]
gcode: ...

Since the command M106 already exists, you have to add a rename_existing parameter:

[gcode_macro M106]
rename_existing: M106.1
gcode: ...

If you ever need to run the original M106 command, you can use M106.1 in the above example.

thanks for your help, it works.
