Exhaust Fan is always off

[Savety_16 (Max Mayer)]

Hi,

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.

Hi,

I am very sorry, for bothering you all.
I just found out that the issue is not related to any software settings or so.
There was a broken cable on the fan.
After repairing this, everything is fine now.

Amazon has a good return policy, if I were you I’d return it.
