Hi! This is my first post so the statement sounds likes this.

Some of the routers have Pulse-Width Modulators (PWM). To regulate their speed with something like (or it is) potentiometer.
Im new to electronics and collecting some info about CNC which I will make soon. It will have index pulse card.

So the question is:
How can I modify this PWM cheap to regulate through Mach3? Because the pwm`s aren`t so cheap (98.00$)
And how to make indexing pulse card by your self? Again (26.31$)

I plan to make this cheap (if I can) and easy to run components throught Mach3.
I might be repeating post so sorry! Hope to see some answers soon! Thanks!

Edit: Sorry by mistake I have might not placed it right where it belongs!
