In Cutom GCode 740, if Cut through is not selected pause time is added in GCode. If Cut through is selected, Pause is removed from GCode. In neither case is Laser power set. Cut through does not occur. Bug?
In GRBL device, if Cut through is selected, laser is powered, pause occurs. However laser power is then set to zero before continuing. Why? Normally if you have cut through you would want to continue cutting.
