Lazrit + LaserGRBL: SVG Workflow for Open-Source Cutters

LaserGRBL is the free open-source alternative to LightBurn for GRBL-based laser controllers (most diode lasers, some CO2 conversions). Lazrit's SVG output works directly — LaserGRBL traces and rasterizes the SVG into GCode.

3 lifetime exports — no credit card.

Import steps

  1. Export Lazrit SVGWorkspace → Export → SVG.
  2. Open in LaserGRBLFile → Open File → pick the SVG. LaserGRBL converts to vector cut path.
  3. Set power and speedLaserGRBL doesn't auto-tune for material — set spindle speed (S value) for power and feed rate for speed.
  4. RunConnect to the controller via USB, frame the job, hit Play.

Diode laser tuning

Most LaserGRBL users are on 5–10W diode lasers. Cut speeds are much slower than CO2 — start at 1 mm/s on 3 mm plywood.

Layer handling

LaserGRBL handles a single layer at a time. For cut + engrave files, run them as two passes.

Frequently asked questions

Does LaserGRBL handle the Lazrit engrave layer?

Yes, but as a separate file. Export the cut layer and the engrave layer separately and run them in sequence.

Is LaserGRBL really free?

Yes — open source, no subscription.

Will Lazrit add native LaserGRBL preset support?

Not planned — LaserGRBL reads standard SVG so no special export is needed.
