Custom Start Gcode

Recommended Posts

Posted (edited) · Custom Start Gcode

I prepared a custom start Gcode for my E3D BigBox in Cura 2.5.0 Beta. But after slicing there is an additional Gcode before my custom start Gcode.

;FLAVOR:RepRap

;TIME:4698

;Filament used: 3.26804m

;Layer height: 0.2

;Generated with Cura_SteamEngine 2.5.0-BETA

M190 S75      ;)

M104 S215      ;)  I want to eliminate this 3 lines

M109 S215    ;)

; below is my custom start Gcode

M140 S75

M104 T1 S120

M109 T0 S120

M109 T1 S120

M104 T1 S210

....

....

....

How can I eliminate above 3 lines of Gcode before my custom start Gcode?

Kind Regards,

Franz

CuraEngine checks your start gcode and sees if you use the {material_print_temperature} variable to heat up the nozzle. If you don't, CuraEngine adds its own nozzle heating gcode.

Make sure your start gcode contains the line M104 {material_print_temperature}, and CuraEngine should no longer add its own lines.

Thank you!

.... and the line: M140 S{material_bed_temperature} to get rid of M190 S75 .

BTW is there a placeholder for "first_layer_bed_temperature" in cura 2.5+ ?

I can't find a comlete list of this placeholders.

All available parameters can be found in the file named fdmprinter.def.json in resources/machines
