Hi Craig,
To tell the truth, I'm rather ambivalent about the charge pump myself.
What really bothers me is that it doesn't work. It makes me wonder if there might be other things that may not work as I go forward.
Right now, the only things connected are the steppers and the parallel cable. Movement is very smooth and I haven't done any tuning yet.
I think my Mach setup is right so that leaves something wrong with the G540 or the cable.
I have checked the cable for continuity. Wish I had a spare.
I'm thinking at this point I may just send it in to Gecko and have them do a quick check on it.
Thanks,
Walt
