New to the forum and looking for some help with our new fiber laser with the preview 3 controller. On our new laser the scrap conveyor will only run with the "coffin" cover closed. This is a headache when removing cut parts, as well as trying to brush slag from the scrap conveyor. Mazak will not give any help on the parameter needed to run the conveyor with that cover open, for "safety reasons". We have a STX CO2 where we have the cover locked out. Can anyone point me in the right direction in getting the conveyor to run all the time?
