Mystery Lines Showing Up

[Stroonzo (Jeff)]

I am pretty confident your problem is the min power setting being too low (especially considering the difference from Max power).

You also should go into your controller configuration and check the following:

Ruida / LightBurn won't cut below 10mm/s

This isn’t a LightBurn issue, but a Ruida one that’s quite common. There’s a controller setting called “Start Speed” that defaults to 10mm/sec. At that speed, power starts ramping up from Min Power to Max Power. Cutting at or below that speed means you’re using Min Power only, so if you’re cutting slow, set both Min and Max power the same and you’ll have no issues.
