I have a DIY CNC Router, Running Mach 3, with a TB6560 controller. I want to build a better setup, but first play around with a spindle to see if I like it. After research I found that all I must do is hook up some jumpers to the control board, and over to a PWM like this
that is the same as this?
And set it up in Mach 3.
Is this all I need to regulate a DC spindle? I feel like I am missing something.
