Yes, it must be in the default position mode. In position mode, if you are at 0.01" per click, and you > turn the wheel 20 clicks, you WILL get 20 x 0.01" or 0.200" of motion. > It doesn't matter how fast or slow you turn the wheel, or how slow EMC > can move due to feed override - you will get what you asked for.

But, in velocity mode, will it keep up with the encoder counts up to the max velocity? That might be what I should be using, then. I will try it!
But, finally, when in position mode, why should the jog override slider affect how the MPG controls the machine? The dial sends not only position but velocity information, so the jog override slider is redundant for MPG moves. Any thoughts?
