Tom,
Ok I might understand. The difference between seeking a position and a velocity is the command. When seeking a velocity you use the "jog" command. I always configure the axis channel and the encoder channel to the same number. So Axis 7 uses encoder 7. 7 was chosen because I may want to later add an A and possibly a B axis. Having the Spindle at 7 protects it from confusing it with a position VS a velocity system and/or overwriting it with a future A or B. So far, I haven't had any luck with configuring the Spindle as a PID controlled drive. I guess I wasn't sure it was possible and since open looped was relatively easy, it made sense to set that up first. I will experiment tomorrow. With luck that will be all I need to start making chips!
I suppose there is a way to have the Step Response use a Jog instead of a Move? Is that automatic? As always. I really appreciate your help!
