Lychee Slicer 7.6.6

  • Lychee Slicer
  • Minor update

This release makes your projects more resilient to corruption — with file integrity checks when saving and automatic recovery when opening — and fixes several file-loading issues along with the screen size for the Phrozen Sonic Mighty Revo 16K.

New 🎉

Automatic Recovery of Corrupted Files

If a .lys or .lyt file is corrupted, Lychee Slicer now recovers it automatically from your most recent valid auto-save — no error, no lost work. When automatic recovery isn't possible, a dedicated window lets you browse every available backup and pick one to restore yourself, so you stay in control even in the worst cases.

File Integrity Check on Save

Lychee Slicer now verifies that your file was written correctly every time you save. If something goes wrong, you're warned immediately and prompted to try again — preventing corrupted files before they happen.


Fixed 🐞

File Opening & Loading Issues

Fixed several cases where files would fail to open or stay stuck on the loading screen, including specific models that wouldn't load. Opening your projects is now more reliable.

Incorrect Screen Size — Phrozen Sonic Mighty Revo 16K

Corrected the screen dimensions for the Phrozen Sonic Mighty Revo 16K, so slices map accurately to the printer's display.
