Strange behaviour: Lower power at low cutting speeds

[LightBurn (Oz)]

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.
