Not the most elegant solution - but i was able to rewrite the code according your suggestion, thank you very much! I have added a NULL material with a temperature of 0°C for extruder0, so Marlin's "cold extrusion prevention" will skip extrusion for extruder0. So here's the code just for reference: ;-------------------------------------- M117 Initializing... M107 ; fan off M140 S{material_bed_temperature} ; set bed temp M104 T0 S{material_print_temperature_layer_0, 0} M104 T1 S{material_print_temperature_layer_0, 1} G28 ;Home G1 X30 Y30 Z30 F5000 ; Set offset for smaller print bed (no print area definition in cura) G92 X-30 M190 S{material_bed_temperature} ; set bed temp M109 T0 S{material_print_temperature_layer_0, 0} M109 T1 S{material_print_temperature_layer_0, 1} M117 Levelling... G90 ; Absolute positioning M82 ; Extruder in absolute mode G29 ;Level Bed M117 Priming... T1 G92 E0 ; start line G1 X200 Y2 Z0.7 F5000 G1 F800 E5 G1 X40 E30 F1000 G92 E-3 T0 G92 E0 ; start line G1 X200 Y0 Z0.7 F5000 G1 F800 E5 G1 X40 E30 F1000 G92 E-3 T{adhesion_extruder_nr} ;--------------------------------------

I'm trying to wrap my head around transferring a custom start gcode from repetier/curaengine to Cura 3.6.0. The printer is a custom modified dual extrusion device with a specific code to fulfill my needs: - for single material i'm only using the second extruder - material is retracted after print and needs to be primed for a specific minimum length before starting a new print After some searching i found: http://files.fieldofview.com/cura/Replacement_Patterns.html but even with this information i can't understand - how to set (conditional) temperature for a specific extruder - let cura acknowledge this as an override for its default behaviour Here's a sample code from repetier/curaengine. any help would be appreciated very much: ;-------------------------------------- M117 Initializing... M107 ; fan off M140 S{BED} ; set bed temp {IF_EXT0}M104 S{TEMP0} T0 {IF_EXT1}M104 S{TEMP1} T1 G28 ;Home G1 X0 Y30 F1500 M190 S[BED] ; set bed temp {IF_EXT0}M109 S{TEMP0} T0 {IF_EXT1}M109 S{TEMP1} T1 M117 Levelling...
