Ballendo,
These are inexpensive 24v unipolar steppers, single shaft. I'd LOVE to
have 150 oz/in DOUBLE shaft motors, and I'd probably put an encode and
the handwheel back on. I'll save that for later. Right now, I'm going
slow. no resonance noted, but I haven't really rung it out. The Z axis
is the one I'm worried about. Oh yeah, I bought the Sherline CNC
retrofit hardware, VERY nice. Pix to follow, when I can get some taken.
