Would need som help to figure out how to wire and get the laser control to work.
My setup:
Mach3
BITSENSOR 4 Axis CNC MACH 3 USB Controller
15W Blue Laser with 12VDC powersupply.
Laser has the following connectors:
[+ (+12V)] [ - (0V)] [PWM/TTL]
[-] TTL/PWM [+]

Bitsensor has the following pins for analog/PWM:
[10V] [5V] [GND]
[AVI ]
[ACM]

I have successfully got the 0-10V control to work when hooked up with a 10V supply to [+10V] [ACM] and [AVI] for the "signal" but I'm not sure how to wire it with the laser as there are several different voltages at play and no documentation available.

Now I'm controlling the laser by shorting the [-] TTL/PWM [+] pins with a relay (NC) controlled by an output.

Would be gratefull for any help with this.
