Temperature Issue for multiple extruders

Recommended Posts

Posted · Temperature Issue for multiple extruders



I'm having an issue with the start gcode for the custom printer definition I'm working on. I need the printer to heat the hotend to the temperature for material 1. However, if multiple materials are being used with different printing temperatures, the highest temperature is set to T0 regardless if that material is assigned to T0. I have copied my start gcode below and bolded the two lines that are causing problems. 


M98 P/sys/messageprintstart.g

M104 S{material_print_temperature_layer_0} T0 ; set extruder temp

M140 S{material_bed_temperature_layer_0} ; set bed temp

G32 ; home xy

M190 S{material_bed_temperature_layer_0} ; wait for bed temp

M109 S{material_print_temperature_layer_0} T0; wait for extruder temp

M98 P/sys/homeu.g

G1 X-12.5 Y0 F6000 ; Position Tool Head for filament change


G1 U0 F2000 ; Position filament selector for bay 1
