Pete I will take your word on it you are the guru here. I honestly don't
know. Would you recommend keeping it and trying to get a drive to fit it,
I would need to find another similar motor on ebay. Besides I am starting
to hijack this poor guys thread here. I am open to whatever will be the
best
Andy,
Honestly man I have no idea. As I said there ARE NO DRIVES LOL.. It
is gutted. I only have a single X axis motor and some wiring in this
beast. The rest was sacrificed to the parts gods on ebay by the previous
owner I guess. I posted the information on the motor I got from an
enginee

No, because they are very good :-)
My comments were based on the assumption that you already had
expensive motors and were looking to junk them. That would be silly.

I would suggest that that would be a downgrade. Buying resolvers new
would be needlessly extravagant, they cost a fortune, but if you
already have them then they are superior t
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

My next lathe conversion is very likely to be using brushless DC
servos and resolvers.
I like resolvers. They have super-high precision and are very tolerant
of interference, contamination, heat etc.

Using halcmd show I've validated the switch inputs are working properly.
Any idea what may be wrong?
