I have been happily using Lightburn and my laser for some months, many many hours of cutting.
Yesterday I held a workshop and we had superb cuts. Today the speed control is wrong. Yesterday we cut with 400 mm/min, today I have to reduce the speed to 10 mm/min for penetration. Visually it looks like the laser is actually travelling about 400 mm/min with this setting.
If I run the identically same programs as used yesterday, there is just a burnline on the surface. Geometry is correct though.
I guess some register setting has got the wrong value. How can I troubleshoot and fix?
Not to cast aspersions on your workshop attendees, but it’s amazing how many settings change while folks become accustomed to mousing & clicking around a new-to-them program while concentrating on the laser rather than the UI.
