I've "recycled" an old laser module from an old CNC project.
I would like to try this laser with my Stepcraft 420 and Mach3.
In the driver the connection pins are named TTL, not PWM.
There's a way to let it works with the DB15 of the Stepcraft?
I've connected it on pin 2 (ground) and pin 13 (positive), but it seems not working.
I'm not really sure to have set the right parameters on Mach3 (Motor Outputs, Output Signals, Spindle Setup).
Can you help me? Thanks
