Which is 834372 clocks, and this then includes the 200hz jog-thread? So 
its got to be running at full speed to meet its 1 millisecond schedule 
reliably.

I don't think I have a lot more to add, home switches are about it. Noise 
filters to be made for that I expect. Andy's gearchange stuff is in 
there as far as addf's go, just not activated yet. Some xml stuff to 
hook it up is next, but until I can actually turn the spindle again, 
I've not worked on "hooking it up" to the pyvcp leds yet.

Thanks Peter.
