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.

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.
