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.
