The short answer
If your laser has a GRBL-type controller — most diode lasers — LightBurn Core is enough; on LightBurn's EU store it cost €105.95 on 26 September 2026. If you run a CO2 laser with a Ruida controller or a galvo laser, you need LightBurn Pro at €211.95. Both are one-time purchases for commercial use, activate on up to three computers, PC or Mac, and include a year of updates. After that year the software keeps working; renewing only buys another year of updates.
- Diode (GRBL) → Core
- Ruida CO2 or galvo → Pro
- One-time licence, 3 computers, 1 year of updates
