Hi Doug
Guess I better explain more,
This is a big machine,I will be spinning nuts on 11/2"dia
screws, Plenty of load/inertia to overcome. I was thinking of using
the servos I have on hand hand. Seems that trying to run two servos
from one set of pins is asking for trouble.
I could go back to the BIG steppers [2300oz in] but will lose
performance.
If anyone has a "trick' to keep two servos from playing tug of war
when run with Geckos I would love to hear it!

thanks
Carl
