I had a spare motor that came with the mill, but I hadn't tested it
yet. I got it out, it ran great so I mounted it on the mill. No
luck, it does the same thing. I turned the belt and the ballscrew
inside the head and it couldn't have been any freeer. (freer? never
spelled that before) I'm pretty confident in the deskcnc control
board and the gecko drives, unless during the series of short moves
(less than .005") they get ahead of the machine, but I don't think
that should happen. I'm wondering if running the combination of all
three drives is somehow depleting the current to that motor, but I
doubt this too. The power supply is just like you (Les) explained
to me a couple years ago. 1 transformer, a bridge rectifier
(actually three in parallel because they were there) and some
capacitors for filters. It seems like it almost has to be in my
acceleration curves, but I can't seem to work it out right.

Thanks
