Dual extruder start script gcode placeholders

Recommended Posts

Posted · Dual extruder start script gcode placeholders

I have set up a dual extruder printer as a custom fff with marlin, ticked off dual extruders and I am trying out a start script.

 

This works fine:

M140 S{material_bed_temperature_layer_0} ; set bed temp

as expected becomes:

M140 S105 ; set bed temp
 

This fails:

M109 R{material_print_temperature} T1    ; Cura set extruder temp and wait

Results in Extruder T0's print temperature

 

This from all the examples I have found, also fails:

M109 R{material_print_temperature_1} T1    ; Cura set extruder temp and wait

That line stays the same in the gcode file

 

I have also found this reference to all placeholders but without a solution:

Am I using the wrong placeholder?

Hi @thrmttnw, welcome and a quote at first:

 

 

I presume it works in the same way for all extruder specific settings. You can even combine it with the '....extruder_nr' placeholders instead of hard-coded digits if you like.

For example:

 

M104 T{adhesion_extruder_nr} S{material_print_temperature_layer_0, adhesion_extruder_nr}

Thanks!

 

Difficult to find that info among the many many older now wrong start scripts out there. Could be great if moderators could make an original post about this sticky in the forum, until next time these patterns change.
