I have read many posts and it seems that others have the same problem, but after dozens of tests I have not found a solution.
Laser burn on start and end and change direction of cut line.
I’ve tried varying the “min speed” and “max speed” settings a lot, but they don’t seem to work in cut mode.
The burn is more visible with the lens out of focus
Laser Gbos 1300x900 mm
Controller Ruida RDC6442s-b(ec)
Glass Tube 150W
Cut through mode is diable.
Start speed value is 8 mm/s.
Parameters are reset to default.
I’m going crazy, but it seems the controller doesn’t handle the acceleration ramp in cut mode.
