The CamFive machines do not use RDWorks. They use a Ruida controller, but it’s got different firmware in it from Yueming Laser. They use SmartCarve by default. I’ve got a 4032K that’s working great with LightBurn. However, I’ve never run it via USB, always done Ethernet. Grab that Ethernet cable from inside the machine, plug it in and config an IP Address in the machine and your computer. MUCH more stable, no drivers needed, and WAY faster as well. That may fix you up.
