I bought a 7i43 and a couple 7i42TAs awhile back and I am just getting around to using them to build a new controller box for my 9x20 lathe.
I currently use a DPDT switch to reverse directions and a variable resistor to control speed. I have a homemade encoder on the spindle. The spindle motor is a treadmill motor with a DC controller that will accept 0-5v input in place of the variable resistor to control speed. I built a PWM to Analog board to put in the controller. I have seen recommendations about using a stepgen instead of a PWMgen. Which would be the better choice? Why?
