RE: [CAD_CAM_EDM_DRO] Re: Servo as a Sherline spindle motor ?

Thanks for the note; in fact, you bring good news ! It means the motor
I've picked is an appropriate size.

You see, I have a pretty old Sherline with the variable speed _AC_ motor
right out of a small sewing machine, the speed control no more
sophisticated than a cheap light dimmer.

I'm quite sure what I'm planning will be an upgrade.

I'm curious about your statement about tradeoffs re: interface device. I
was planning on just using the parallel port. Am I missing something ?
