Checks

What is checked, and what can be fixed.

CheckWhat it doesStatus
OverhangsFlags faces steeper than your configured threshold. Fixed by reorientation, or a real rounded fillet on STEP models (a flat mesh chamfer otherwise) where reorienting alone cannot clear it.Auto-fix: reduces, rarely clears
Thin wallsGrid-accelerated ray casting measures wall thickness across the mesh, flagged against your nozzle's two-perimeter minimum.Opt-in fix
BridgingFlags unsupported flat spans over roughly 8mm for the configured profile.Opt-in fix
Tip-over / bed contactWarns past roughly a 4:1 height-to-footprint ratio.Opt-in fix
