[Problems with second extruder in CURA. (Leapfrog Creatr HS)]

Hi Michael,

I had the same issue as you and you made me understand what is wrong. The issue is located in the start g-code. It is actually missing the setup for the left extruder. 

I've managed to solve this by duplicating these lines and adding a start line for each extruder

https://marlinfw.org/docs/gcode/T001-T002.html 

printer start g-code

M107 ; start with the fan off

G28 X0 Y0 ; home XY axes

G28 Z0 ; home Z

G92 X0 Y0 Z0 E0 ; reset software positions





;*** Start Dual Nozzle/Bed Preheating ***

M140 S{material_bed_temperature_layer_0} ; start preheating the bed

M104 S{material_print_temperature_layer_0} T0 ; start preheating hotend

M104 S{material_print_temperature_layer_0} T1 ; start preheating hotend



;*** Wait until temperature reached ***



M190 S{material_bed_temperature_layer_0} ; heat to Cura Bed setting

M109 S{material_print_temperature_layer_0} T0 ; heat to Cura Hotend

M109 S{material_print_temperature_layer_0} T1 ; heat to Cura Hotend



;*** End Preheating ***



G1 Z15.0 F180

T0

G92 E0 ; zero the extruded length

T1

G92 E0 ; zero the extruded length

G1 E3 F200

T0

G92 E0 ; zero the extruded length

T1

G92 E0 ; zero the extruded length

G1 F225

Left extruder start g-code
 

T1 ; Selecting tool

Right extruder start g-code
 

T0 ; Selecting tool

 

 

fyi; left it T1 and right is T0. It is not a typo
