Hi Rich, thanks for the info.

As far as lube lines go I don't have any, just some grease or oil fittings
that I was going to remove, thread the holes and put some lines in there for
an auto lube system. The spindle seems to be tight and quiet. Overall in
nice condition, just needs some motors and electronics. I'll take some
photos of before, during, and after shots and post them when I'm done.
Sending you an offline message for the pics of the DM2000 and the g-code.
