The laser cannot engrave and cut, even when we try manually with the control panel: There is no laser output. (the laser worked during the first debugging).
Another fact which may be the rreason: the cw-3000 water cooling did not sound properly at start up. It seems to start with low current. And when the current is cutting off the water cooler doesn't sound. But water circulates.
I need your help because the equipment is not well documented.
