Compressed file size is not working memory. Unrelated archive assets stay compressed. Large scenes can still exceed browser or GPU memory.

Inspection boundaries and sources

Marlin linear subset: G0/G1, G21, G90/G91, M82/M83 and G92. Homing leaves coordinates unknown. Temperature and fan commands are recognized without simulation. Accounting stops at any other unsupported command. Use a supported excerpt with explicitly known starting coordinates for a complete report. No printer control or time prediction.

Paths show logical XYZ coordinates from the supported Marlin linear subset. Machine offsets, bed compensation, acceleration, firmware configuration and thermal behavior are not simulated. Layer and feature comments are slicer annotations. In their absence, extrusion-height changes are only observed groups. The G-code interpreter does not predict print time or mass. Slice results label engine time and filament-length estimates separately; no successful-print prediction is made.

Built with Three.js, CodeMirror and the MIT-licensed Kiri:Moto FDM engine, loaded from this site. No remote parsing service or model is required.
