My charge pump is setup to run whenever EMC is running - you may choose to have it disable when E-Stop is activated, etc. Here's what I believe is on my machine (too cold to go fire up and this is what I have in my archive folder on the laptop), the charge pump board I got from CNC4PC.com needed a quicker pulse than my servo thread IIRC so it's in the base thread, if you can run it in the servo thread instead it would probably be better as to real time performance, I have been known to be mistaken though :)

I am using the stepconf wizard and have set pin 1 as charge pump output. However when I run emc, I never get any charge pump output. For testing I put an axis step output on that pin and I can see the steps coming out. I am using the 8.04 live CD.
