General Mach Discussion / Re: Send PWM signal from Geckodrive G540 to PC

However, I've been looking everywhere to see if it'd be possible to send a PWM signal over the parallel port, from a Geckodrive G540 to a PC, as input that Mach3 would recognize (maybe a 50% signal does something, while a 75% does something else).
That would not be possible.
Mach3 can generate a variable PWM signal (based on the S word in the Gcode) which could then be sent via the Parallel Port to the Gecko G540.

We're building a machine that needs an input to the computer to tell it to either reverse feed, continue forward, or stay stationary
Sounds like an ideal job for Mach3 or Mach4 but we would need some more detail of what you are intending to achieve.
Tweakie.
