Getting this error on each layer: Unknown command:"_ON_LAYER_CHANGE

Hi all, I'm getting my VCore 3.1 ready (first build) and slowly tuning the printer setting and filament settings. But I keep getting this error on each layer. Unknown command:"_ON_LAYER_CHANGE and have no clue what it means I'm using Prusaclicer Start G-code

M190 S0 ; Prevents prusaslicer from prepending m190 to the gcode ruining our macro M109 S0 ; Prevents prusaslicer from prepending m109 to the gcode ruining our macro START_PRINT EXTRUDER_TEMP=[first_layer_temperature] BED_TEMP=[first_layer_bed_temperature]

any idea what this error is? Thanks in advanced for your time.

printer.cfg

Solution:

_ON_LAYER_CHANGE isn't a thing in RatOS 2.0, remove _ON_LAYER_CHANGE from your slicers "custom g-code" layer change section.

Your slicer is outputting that command and klipper doesn't understand it Look in your slicer and disable it

Alternatively, you can implement it yourself by manually pasting the following into printer.cfg:

[gcode_macro _ON_LAYER_CHANGE]
gcode:
    SET_PRINT_STATS_INFO CURRENT_LAYER={params.LAYER|int}

[gcode_macro _ON_LAYER_CHANGE]
gcode:
    SET_PRINT_STATS_INFO CURRENT_LAYER={params.LAYER|int}
