General Mach Discussion / Re: Multiple PWM signals

Hello Alex,
Thanks for the info. The HyCNC seems to be similar to the kflop although I'm sure it lacks a lot of the functionality of the kflop. I've used the kflop motion controller before but found it a bit tedious to keep it synchronized with Mach3. I'm thinking of doing what you said using a D/A converter, but maybe sending out serially 8 bits to the D/A register. I would have to write a routine to pump out the 8 bits with the right timing. If that's possible, I would only need something like the DAC5574 from Texas Instruments and some other stuff to interface it with the parallel port. Again, thanks for your help.
