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

Recommended Posts

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


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


    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
    G92 E0 ; zero the extruded length
    G92 E0 ; zero the extruded length
    G1 E3 F200
    G92 E0 ; zero the extruded length
    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

      • S-Line Firmware 8.3.0 was released Nov. 20th on the "Latest" firmware branch.
        (Sorry, was out of office when this released)

        This update is for...
        All UltiMaker S series  
        New features
        Temperature status. During print preparation, the temperatures of the print cores and build plate will be shown on the display. This gives a better indication of the progress and remaining wait time. Save log files in paused state. It is now possible to save the printer's log files to USB if the currently active print job is paused. Previously, the Dump logs to USB option was only enabled if the printer was in idle state. Confirm print removal via Digital Factory. If the printer is connected to the Digital Factory, it is now possible to confirm the removal of a previous print job via the Digital Factory interface. This is useful in situations where the build plate is clear, but the operator forgot to select Confirm removal on the printer’s display. Visit this page for more information about this feature.

      • Ultimaker Cura 5.6 stable released
        Cura now supports Method series printers!
        A year after the merger of Ultimaker and MakerBotQQ, we have unlocked the ability for users of our Method series printers to slice files using UltiMaker Cura. As of this release, users can find profiles for our Method and Method XL printers, as well as material profiles for ABS-R, ABS-CF, and RapidRinse. Meaning it’s now possible to use either Cura or the existing cloud-slicing software CloudPrint when printing with these printers or materials
