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

      • UltiMaker Cura 5.3 stable released
        In this stable release, Cura 5.3 achieves yet another huge leap forward in 3D printing thanks to material interlocking! As well as introducing an expanded recommended print settings menu and lots of print quality improvements. Not to mention, a whole bunch of new printer profiles for non-UltiMaker printers!

      • Here it is. The new UltiMaker S7
        The UltiMaker S7 is built on the success of the UltiMaker S5 and its design decisions were heavily based on feedback from customers.
        So what’s new?
        The obvious change is the S7’s height. It now includes an integrated Air Manager. This filters the exhaust air of every print and also improves build temperature stability. To further enclose the build chamber the S7 only has one magnetically latched door.
        The build stack has also been completely redesigned. A PEI-coated flexible steel build plate makes a big difference to productivity. Not only do you not need tools to pop a printed part off. But we also don’t recommend using or adhesion structures for UltiMaker materials (except PC, because...it’s PC). Along with that, 4 pins and 25 magnets make it easy to replace the flex plate perfectly – even with one hand.
        The re-engineered print head has an inductive sensor which reduces noise when probing the build plate. This effectively makes it much harder to not achieve a perfect first layer, improving overall print success. We also reversed the front fan direction (fewer plastic hairs, less maintenance), made the print core door magnets stronger, and add a sensor that helps avoid flooding.

        The UltiMaker S7 also includes quality of life improvements:
        Reliable bed tilt compensation (no more thumbscrews) 2.4 and 5 GHz Wi-Fi A 1080p camera (mounted higher for a better view) Compatibility with 280+ Marketplace materials Compatibility with S5 project files (no reslicing needed) And a whole lot more  
        Curious to see the S7 in action?
        We’re hosting a free tech demo on February 7.
        It will be live and you can ask any questions to our CTO, Miguel Calvo.

      • UltiMaker Cura Alpha 🎄 Tree Support Spotlight 🎄
        Are you a fan of tree support, but dislike the removal process and the amount of filament it uses? Then we would like to invite you to try this special release of UltiMaker Cura. Brought to you by our special community contributor @thomasrahm
        We generated a special version of Cura 5.2 called 5.3.0 Alpha + Xmas. The only changes we introduced compared to UltiMaker Cura 5.2.1 are those which are needed for the new supports. So keep in mind, this is not a sneak peek for Cura 5.3 (there are some really cool new features coming up) but a spotlight release highlighting this new version of tree supports.
