Andy,
Like I said I would think about using the original motors if I actually
had both of them. I only have the X motor here now so I wanted to have
matched motors and drives for both axes. Still have a lot of cleaning and
scrubbing and rewiring to do before I really have to worry about that so
not in a huge hurry hell I may change my mind. Brushless DC motors with
resolvers are not cheap on ebay tho. I could buy a complete motor and
driver brand new for what I would pay for a used one like I have on the X.
The machine has a heavy 1-1 belt drive on both axes so I could actually run
about any motor I want on it even a big stepper would work actually but I
want to try to go with an AC servo if possible. Peace
Pete
