I love Mach3 it has a LOT of nice features!

Mach even has a built in PWM spindle motor driver control section built in. It will output a PWM signal on one of the printer port pins. I took that signal and use an opto isolator to drive a mosfet driver IC and mosfet to control my modified dremel tool! Mach even has the P.I.D. integrator functions built in for speed feedback control! the software does everything!
