Yes the motors have tach's. Everything does work now, but upgrade is needed
because of antique control. The encoders are Heds 9000 series with 500 cpr.
Each one has 3 green wires to ground, three red, and 3 black. I will trace,
more clearly & mark the wires, and take photos. The x and y encoders are
driven by a wheel that contacts the machine's moving table. Protrak used
these for years. I plan on changing the encoders eventually and mount
either to the motor or ball screw, but I would like to see if I can get the
axis to move first.
