Just thought I would update this thread as well as my lathe build thread.
I have the controller mostly wired now, have the spindle running nicely and have the Z axis running at 10m/min. I am waiting on a small motor for the X axis coming so may be a week or two before I get that and I am able to test out some actual part making.
I was playing around with the MPG yesterday and I am liking it very much. It is very smooth in all of the three scales and it does not buffer up the pulses like the parallel port and other controllers do. What I mean by that is I can put it to the max unit per click, which is for me 1mm/click and I can wind the MPG as fast as I like and when I stop winding the axis stops. If trying that with the parallel port or SS or ESS then the axis would continue moving long after the MPG had stopped rotating.
Anyway heres a vid of the MPG in action.
