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

[Michael_pf 0]

Hello,

I'm currently trying to get a Leapfrog Creatr HS to work with CURA. 

After some struggle I got my first decent Prints. Printing with the first extruder and printing with both extruders works great now.

The only problem is printing with just the second extruder.

 

The second extruder doesn't seem to respond so I took a look at the G-code and found a difference in the codes for first and second extruder (for the same part).

If I exchange the T0 with T1 in the G-code of the second extruder it works.

 

Is there anyway to get CURA to do that on its own?

Is there an explanation why CURA changes from T1 to T0 ?

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
