I have been having a problem lately. Once every few homing procedures
ends with a runaway. I am homing with index. It starts with the axis
movement towards the home switch, then I see it back off about .2", then
reverse towards the home switch again. It then moves very slowly for
about a second, then bolts off away from home at a rate I have never
seen the axis go. I have the max velocities set at just below the rated
encoder pulse rate. The runaway rate is much higher than this. I also
noticed that the position value at e-stop is in the 300 inch range.

I plan on setting hal scope up to record what is happening, but in the
mean time, if anyone has ideas for solutions, I would appreciate hearing
about it.
