Kolega pomógł, znalazłem gcody w Prusa.
Mam tak.
Start
G90 ; use absolute coordinates
M83 ; extruder relative mode
M140 S{first_layer_bed_temperature[0]} ; set final bed temp
M104 S150 ; set temporary nozzle temp to prevent oozing during homing and auto bed leveling
M190 S{first_layer_bed_temperature[0]} ; wait for bed temp to stabilize
G28 ; home all axis
G29 ; auto bed levelling
G1 Z50 F240
G1 X2 Y10 F3000
M104 S{first_layer_temperature[0]} ; set final nozzle temp

Ktoś zechce coś zasugerować (w sprawie gcodów

)
