Posted · Cura unable to slice please review settings and check if your models fit within the build volume are assigned to an enabled extruder are not all set as modifier meshes

My Tenlog Hands 2 dual independent extruder 3d printer has a faulty extruder 1, so I want to try printing with only extruder 2 and I disabled extruder 1. However, now I get the following error message in Cura 4.11.0 on my MacBook Air running MacOS Big Sur 11.5.2:

 

Unable to slice

Please review settings and check if your models:

- Fit within the build volume

- Are assigned to an enabled extruder

- Are not all set as modifier meshes

 

1. The model definitely fits well within the build volume, as it is only about 10cm x 8 cm x 5 cm and the build volume is over double that in every direction and there are no outlying or widely spaced structures.

2. How do I assign or unassign a model to an extruder? I don't recall having assigned the model to any extruder, but with extruder 1 enabled, it slices and with it disabled and extruder 2 enabled, it won't slice.

3. AFAIK, I never set anything in my model as modifier meshes.

 

Both extruders are set to use generic PLA and the printer ran with PLA on 1 and PVA on 2 before the failure. Extruder 1 goes through the motions, but can't actually feed filament into the bowden tube, although it does try. Its internal LED doesn't even come on, so clearly something is wrong with it.

 

Yes, I should fix the failure, but here in Alaska, parts often take a week extra to get, I need to print today, my other printers are too small for this model and nobody else in town is doing 3-D printing commercially, as far as the local filament wholesaler/retailer knows.

MultiSmartPhoneDesktopRack2.stl

I've uploaded my project file for review.

 

Any assistance in getting this one printing on only extruder 2 would be greatly appreciated.

    With your model selected in Cura - look to the lower left of the Prepare screen and you should see a circled (1) and a circled (2) indicating the extruders.  Select (2).

    In this image I have disabled Extruder 1 AFTER bringing the model into Cura.  So the model is now set to a disabled Extruder.  The funky cross-hatch pattern on the part indicates it won't slice.  Selecting the circled 2 on the left will set the model to extruder 2.

    I have a file which cannot slice after resizing. Can anyone help?

    Wow.  Is that ever a mess.

    There are 258 separate meshes assembled to make up the 4 wheels.  The lug nuts are full of flipped normals.

    In it's current form that "assembly" is not repairable (I tried) and consequently it isn't printable.

    If you want to print those you will need to jump through some hoops.

    • Load the Mesh Tools plugin from the MarketPlace.  You will have to restart Cura after loading it.  
    • Load your model and select it.
    • Right click and the top command will be Mesh Tools.  One of the tools is "Split Models into Parts".  Do that.
    • Piece by piece delete one of the rear wheel assemblies.
    • Piece by piece delete one of the front wheel assemblies.
    • Right click and choose "Select all models".
    • Cross your fingers.
    • Right click again and choose "Merge Models".  If it works the model may jump off screen.  Select "Select all Models" and manually set the XYZ location so it's back on the build plate.

    If that worked (it did on a single front wheel) then go to the Mesh Fixes settings and enable "Remove all Holes".  Hopefully it will slice.  This is without touching up the settings.  It still needs a lot of work.

    Remember to turn off this setting when you are done with this print. It is not a setting to leave on generally.

      • 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.
