My XTool D1 Pro 2.0 has started losing connection with Lightburn when I am using fill mode at higher power levels. 50% works fine, but 65-75% is disconnecting. Usually this occurs shortly after starting project. Using USB connection and I have tried different cable. Also installed lightburn 2.0.3-2.0.5 versions and reinstalled the laser config. Offset fill and line seem to work fine at any power level.
This sounds like the power supply cannot deliver the full rated current. The output voltage drops too much and the controller resets.
