Re: nice servos from plotter

No, I didn't have any problems with the encoder wiring. The ground
pin was easy to find as it was connected to the ground plane and
thus all the mounting screws. I guessed that power would be +5
volts, and since there was a pin with a larger trace which was
routed to several chips, I assumed that to be power. I guessed on
channel A and channel B, and of course got them wrong :-) but that
hurts nothing..just swap them.

The motor is DC and only has 2 power wires, red and black. Bog
simple!

What does the 4699A look like? Is it a A size or one of the large D
or E size?
