v0.2.30 Material recipes, LightBurn import and kerf compensation

2026-10-15

Saved panel dimensions now survive startup without being overwritten by defaults.
A preset stores a complete recipe of up to 11 ordered sublayers. Configure a layer, select it, then use From Layer. This captures operations, min/max power, passes, air assist, Z offset, kerf and advanced vector/raster settings. Use E to name the saved row.
Import accepts Beam Bench JSON and LightBurn .clb libraries. .clb: Review converted recipes and skipped entries, expand each recipe to inspect its sublayers, then import or cancel. Export writes JSON. LightBurn speed converts from mm/s to mm/min by multiplying by 60.
Expand a Line sublayer's vector controls and set Kerf Offset in the displayed unit. The value is the path offset, usually half the measured cut width. Positive values expand outer contours and shrink nested holes; negative values reverse this. Zero disables compensation. Preview and machine output use the compensated paths; artwork stays unchanged.
USB presets include Creality Falcon2 Pro 22W / 40W, 400 × 415 mm, Creality Falcon2 Pro 60W, 400 × 400 mm and Two Trees TT-5.5S. The TT-5.5S uses M3 constant power. These presets follow manufacturer documentation and have not been physically tested. Verify workspace and firmware settings before use. Camera and air-pump controls are not configured automatically.
