Assumptions and limitations
Layers count from 1. Their top is first-layer height plus regular height × (layer − 1). New color starts on the following layer. Constant layers only: no raft, adaptive heights or G-code editing. Confirm the slicer preview. Example: 0.3 mm first, 0.2 mm regular and target 10 mm select layer 50 at 10.1 mm using at-or-above.
