Hello,
I have installed a low power laser for marking wood pattern outlines to my cnc router. The machine is driven by an AXBB-E controller and has been trouble free for a couple of years now.
The laser is a 1.6W LED 24VDC PWM=5VDC Three wire - Pos, Neg, PWM
The basic problem is that with the PWM lead tied to pin 17 port 1, the laser is always on from machine startup.
I have tried every configurble setting for PWM, spindle control. Active Hi / Lo, you name it. I think I've tried it with no success and whilst most others struggle to fire their lasers, I am struggling to switch it off.
Please help, it would be much appreciated.
Rgds,
Mirko
