Disable Second Extruder, Prime Tower Settings, Won't Print


Recommended Posts

Posted · Disable Second Extruder, Prime Tower Settings, Won't Print

Going back at least to 3.5.1:


When you disable the second extruder, many changes are made automatically, one of them is setting the Prime Tower X and Prime Tower Y coordinates to 0.


Even with the prime tower turned off, this triggers an error, and won't slice due to "per model settings".




Two problems:

1) Prime Tower Position is NOT a per-model setting

2) There's no reason not to slice due to poor positioning of something you're not using.


I suggest removing the tower position as a "per model settings check".

I suggest tweaking the check to something like " && !(prime_Tower_Is_Enabled?)


Or if I'm doing something wrong, let me know. Currently I just set standby temp to 0 (preventing extrusions but not travels), or add another printer with one nozzle and try to keep them concurrent.

    I'm having some trouble reproducing this. If I disable an extruder, it never tries to change the prime_tower_enabled setting.

    Could you share your exact reproduction steps?

    Install CURA fresh. Allow it to delete old profiles. I added ONLY a generic printer, set for 2 extruders. Use, verify functionality, quit CURA (done in the "before time"). Perhaps yours doesn't do this because you've installed an UM profile in your CURA? (I didn't test that)


    To answer this post, I:

    Load CURA 3.6.0

    Right click, Disable second extruder


    This notice, similar to but out of order from the lower notice shown in previous post appears.:



    Not hard to reproduce on my end! No model, no nothing.


    It seems to happen with Prime Tower enabled or disabled. The option always comes back on regardless of previous state when I enable the extruder.

    Even with your reproduction steps, I still can't reproduce it. I've tried it with a clean install and using the build that we provided, but still no luck.

    Hmmm, at an impasse then. 


    Is there something I could do to help you see it happening in a way that would help?

      • 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 5.3.0-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.
