Awkward behaviour from slicers when slicing my model
Best Answer by jsw:
Ok, now that I took a look at what you are trying to do, I don't think that 'vase mode' is the tool for the job. Vase mode is intended for objects that have a continuous outline, where it will extrude one layer, then progress seamlessly (pun not intended) to the next layer right on top, etc. This model does not have a single continuous outer shell.
However, that did not stop me from trying. 😉
When I sliced it with PrusaSlicer, it was UGLY and I know that it would not print.
When I sliced it with Cura, using the 'spiralize outer contour' mode, it sliced it OK, but I did not try to print it.
My suggestion is to avoid the vase mode for this, as the wrong tool for the job.
RE: Awkward behaviour from slicers when slicing my model
Ok, I downloaded the rigid version and sliced it with both Cura and PrusaSlicer and both of them appeared to slice properly. My hunch is that both would print as expected. The startup gcode looks sane, so there's no reason that it should not extrude filament.
With Cura, I used the 'playback' feature and the extrusion does follow the spiral in the expected path. It's like a 9 hour print so I don't feel like printing it just to see if it prints. 🙂 If you really get stuck, I could probably start it using some tag end filament and abort it after I see that it's printing. Let me know.
Now, this does, however, look similar to a throw-away test object I made over at the local 'makerspace' a few years ago as we were learning some of the advanced drafting techniques. What I ended up with was kind of a spiral 'slinky' thing that everyone had fun playing with. One of the ladies in the class nicknamed it the Mystic Spiral for reasons I won't go into. 🙂 Someone suggested that I add fixtures at each end, so I did.
Anyway, this was an experiment where you took two shapes and promoted them among dimensions and used one to trace the path of the other. It was sliced with Cura and printed on a Taz 5, and sliced and printed without issues in 1-2 hours. I kept it (why?) for some reason and this reminded me of it. I do know that such a thing is possible to slice and print without any issues. See below.

Well, I created the rigid version to overcome those issues coming out of the spiral in the spiral case mode version.
Though using a brim in the spiral vase mode version helped to slice the print properly, I just don't understand why it behaved that way hen I did it first time without a brim.
If you can download the spiral case version and tell me what you think the issue is, I 'll be grateful
And by the way the mystic print is very coooool 😉 😆
Thanks

Sure, let me finish up one little item and I'll try the vase mode one.

@jsw
Thanks. I think I will consider that in the future.
