General Mach Discussion / Re: Multiple PWM signals
« on: July 30, 2013, 07:33:16 PM »
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.

General Mach Discussion / Multiple PWM signals
« on: July 29, 2013, 07:20:00 PM »
Hello,

I am wanting to connect 3 electronic pressure regulators to Mach3.  The pressure regulators are regulated by a 0-10v analog signal and I need to regulate each one to different pressures.  I was thinking about using 3 PWM to analog circuit boards but I'm thinking mach only supports one PWM putput signal.  Maybe I'm wrong,   Anyways maybe someone has a better idea of how I could control these regulators using Mach3. 

Thanks,
