Helix 1.2.7
What's new
- Fixed multi-plate 3MF preview failures — selecting a plate no longer errors with "Native engine could not load this model". The chosen plate is now repacked into a minimal core-spec 3MF the slicer engine accepts.
- Fixed OOM/crashes on large models — extraction now streams via an XML pull parser, so even big files (88MB Monkey / 57MB Stitch) load without running out of memory.
- External part-file meshes supported — models storing geometry in
3D/Objects/object_N.model(referenced by component groups) are now inlined and flattened correctly. - New Prepare & Slice progress bar — real byte-counted percentage, phase labels, and status messages while your plate is being prepared.
- Instant plate selection — tapping a plate card is immediate; extraction now runs when you press Prepare & Slice.
