I am new to Laser engraving and cutting.
I have bought a kentoktool LE 400 Pro Laser, which most likely has GRLB controller.
Unfortunately, when engraving oder cutting something ot does not turn on the exhaust fan at all.
I added a small external fan at the side of my engraving place to get rid of the exhaust, but I feel it should be doing better once the internal exhaust fan would work well.
So my question is, if I forgot to set a setting or if I need to do something in order to turn on the exhaust fan.
It was a brand new Laser so I doubt the exhaust fan is broken.
