Posted · Start G-code for Multi extruder printer

Hey guys,

 

My printer is Raise3D Pro2!

I have this Start code that I need to heats up both nozzles in the beginning in order for them to do the switch if needed.

 

How do I achieve that in Cura?

 

Start G-code:

G90; use absolute coordinates
M83; extruder relative mode
M104 S[first_layer_temperature] ; set extruder temp
M140 S[first_layer_bed_temperature] ; set bed temp
M190 S[first_layer_bed_temperature]; wait for bed temp
M109 S[first_layer_temperature]; wait for extruder temp
G21
M82
M107; fan off
G28 X0 Y0
G28 Z0
G92 E0; reset extruder position to 0
G1 Y5 X5 F3000 ;Move to position
G1 X60 E9.0 F1000 ;Start purge line
G1 X100 E12.5 F1000 ;Finish purge line
G92 E0; reset extruder position to 0

In Prusaslicer it's working except for the temperature of the none active extruder is not going down after the selection:

 

Start G-code

G90; use absolute coordinates
M83; extruder relative mode
M104 S[first_layer_temperature] ; set extruder temp
M140 S[first_layer_bed_temperature] ; set bed temp
M190 S[first_layer_bed_temperature]; wait for bed temp
M109 S[first_layer_temperature]; wait for extruder temp
T[initial_extruder] P0 ; select tool
M116 P[initial_extruder] ; wait for temperature

G21
M82
M107; fan off
G28 X0 Y0
G28 Z0
G92 E0; reset extruder position to 0
G1 Y5 X5 F3000 ;Move to position
G1 X60 E9.0 F1000 ;Start purge line
G1 X100 E12.5 F1000 ;Finish purge line
G92 E0; reset extruder position to 0
M117 Printing...

 

Tool Change G-code

; Custom tool change G-code
T[next_extruder] P0 ; select tool
M116 P[next_extruder] ; wait for temperature

 

Thanks.
