Already been done! I have sold about 30 sets of the servo amp boards, with a few additional components
that would be hard to get in small quantities. I'm running low on blank boards, but could order another
batch if demand warrants it.

I think two of the builders are close to firing up their amps, we'll have to see who gets to that
stage first. I'll know when the questions start coming in!

Yes, the STG card is a bit expensive, but it integrates EVERYTHING on one card. That doesn't
seem so important until you realize that the action of reading the first encoder counter locks the
counters for all axes, and also loads the new DAC values to all axes at the same time. Also,
it has the watchdog function interlocked to the servo amp enables and zeroes the DACs
on a watchdog timeout.
