Re: [CAD_CAM_EDM_DRO] Another BDI question

Hi Jon,

That's great news! I'm sure there are a few BOSS' owners out there!
What are the spec's for a BOSS stepper? I have a pair of OLD SS
M093-FD11's, NEMA 34, 6" long (triple stack?) 300 oz/in, 2.8v, 5.5A,
6wire. I'm thinking of using these on a future FB-2 or ENCO 16 3/8
-sized mill. Hopefully they are still useful? Otherwise, I'm wondering
if my 180 oz/in NEMA 23's are big enough.
