What problem does it solve? Slicing a 3D model produces G-code that is hard to verify before printing, and blindly trusting slicer output risks failed prints or unsafe machine behavior. This Skill runs a real OrcaSlicer build with explicit JSON profiles and renders the actual toolpaths so you can inspect exactly what the printer would do. ## Core Features & Use Cases - Deterministic slicing: Runs OrcaSlicer 2.4.2 from the CLI with explicit printer, process, and filament JSON profiles, resolving profile inheritance chains and failing closed on errors. - Interactive G-code inspection: Generates a local preview.html toolpath viewer with layer scrubbing, feature and speed coloring, travel move toggles, and isometric or top projections. - Honest verification reporting: Writes verdict.json, slice.json, resolved profiles, and slice.log to .harness/, clearly labeling slicer estimates as estimates rather than print-safety certificates. - Use Case: You have an STL of a fluted vessel and want to check first-layer travel, per-layer extrusion, and feature breakdown before committing to a print. Configure slice-config.json, run the slice script, and scrub through the parsed layers in the preview. ## Quick Start Ask the agent to slice the STL model in this workspace using the OrcaSlicer skill and open the generated preview to inspect the layers.
