; PrusaSlicer start gcode for Prusa i3 Mk3
; Based on baseline start gcode 20210316

[[ Other startup gcode if desired...]

; Set initial warmup temps
; Insert this code before the G28 W homing command
M117 Nozzle preheat
M104 S160 ; set extruder no-ooze temp
M140 S{if printer_model=~/.*MK3S.*/}[first_layer_bed_temperature]{else}{max(first_layer_bed_temperature[0],80)}{endif}  ; set bed PINDA warmup temp
; Nozzle warmup before home to avoid driving hardened ooze into PEI surface
M109 S160 ; wait for extruder no-ooze warmup temp before mesh bed leveling, cool hot PINDA

[ Other startup gcode if desired...]

; Begin G28 W homing command
; Home
M300 S40 P10 ; chirp
