/diy/ - Do It Yourself

Hmm, I'm trying to paste this starting Gcode from Cura to PrusaSlicer

G21 ; millimeter units
G90 ; absolute coordinates
M82 ; E absolute
M140 S{material_bed_temperature_layer_0}
M104 S{material_print_temperature_layer_0}
M190 S{material_bed_temperature_layer_0}
M109 S{material_initial_print_temperature}
G28 ; home axis
M420 S1 ; enable mesh leveling
; Lower nozzle and move to start position
G1 Z150
G1 X-130 Y0 Z0.4 F3000
; Extrude about 40 mm by printing a 90 degree arc
G3 X0 Y-130 I130 Z0.3 E40 F2700
; Retract and move nozzle up
G92 E0
G1 E-1.5 F1800
G0 Z0.5
G1 E0 F300

But when I try to slice, PrusaSlicer gives me pic related as error.
It apparently doesn't like any of the M lines, but they're important otherwise it starts trying to do the purge line when it's not hot yet
