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


Recommended Posts

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

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
