I'll have to look up some parts and see how simple I could get it.

But, one other thing is to make sure the following error causes a servo shutdown. I think the sample config does not do that. Mostly what you need to do is move the servo enable to a different SSR position like SSR7, and then add this line to univstep_io.hal : net drvenbl pid.0.enable ppmc.0.dout.06.out
the pin pid.0.enable will be true when in machine-on, after you press F2. If a following error or Estop condition occurs, it will go false, and shut off the servo amps. You can clear the condition and then just press F2 to put it back online. The purpose here is to make sure a following error also causes a servo shutdown.
