Line not cutting through material but fill does

[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.

That’s the controller manual. You’re more likely to find an explanation in the RDWorks software manual, if you can comprehend it:

For cutting processing, the actual power is followed with cutting speed, lowers peed, lower energy, high speed high energy, so that we can guarantee the whole process of cutting energy evenly. So the minimum power corresponding to the energy at minimum speed, generally the minimum speed is 0, but if set takeoff speed, so the minimum speed is takeoff speed; the maximum power corresponds to the layer speed.
