I'm adding a diode laser to my shopsabre4896 and wincnc said there could be problems with 3 pin laser sharing a ground between 12v power and pwm. They said that 12 volts could travel back to my wincnc controller card and ruin it. does anyone know of a 4 pin diode laser where the pwm circuit is isolated. I know the j-techs are, but I'm trying to do it on the cheap.
thanks,
Ben
