Description of the bug

Import .prz into UVtools and remove islands. Accept suggestions for wait times, number of bottom layers, etc. Save file. Attempt to print on printer. When print starts, the plate lowers into the vat, instead of exposing the first layer, it very slowly rises along the z-axis, after which it lowers even more slowly back into the vat, but not near enough to zero, then starts printing even though the plate is at a considerable distance from the screen, and everything remains on the film. It either does this or some variation, the end result it the plate never gets to zero to expose the first layer. Yes, it's doing a "blank" first layer but doesn't lower the plate to do the first "non-blank" first layer.

EDIT: attempted to attach .zip with lys and prz files, but they were too large. I can copy them up somewhere and provide a link if necessary.

Here is a video of the behavior: https://photos.app.goo.gl/1phGKzbAtNL2L3xg7

How to reproduce

Import .prz to UVtools, prepare file, export, attempt to print.

Try to remove VAT and place a papper. Print same file again and original without UVtools to confirm.

Ah, geez, why didn't I think of that. With a freshly sliced file the behavior continues. The issue is not with UVtools! I'll close this issue for you!

Thank you for your help!

Yeah, when something is odd, always try original file. These machines firmwares are very bad, by now I expect everything...
