Your killin me!

For now I will probably just use the macro to make it wait then use a switch to change the speed. Can you do a post on ...

I wish I did. My Hurco used a speed control board but it required strobes from the cpu. I am just having the machine wait while I crank up the speed. I have not gotten an answer about where "true spindle speed" comes from or how it is derived. That might be a good one for Scott. I was thin...

The manual shows the plot of the sum abs error. So that is what I was using.Here is a fresh plot.

I guess at that point I had the kd/kp done but not the kv1. Are you saying that for the AMC's in current mode that I don't want to set any kv1? I guess I'm a little confused. What should I do? I am running the AMC's all in current mode because the one B25A20 does not seem to have velocity mode as an...
