No need for that.
If you fit an encoder (even a home made one) you can manually crank
the spindle and EMC2 will move the carriage (and handle the fe

Thanks Andy for your inputs.
I'm also reading up STEPGEN. My favorite answer to most questions is "all of
the above".

Thanks Gene,
That's very helpful. Sounds like you've covered a lot of ground that I've just
begun to explore. But I've just about concluded what you suggest: designing a
2 motor spindle drive that uses the reqular DC spindle motor for turning, and a
stepper for threading, with some way to kee

The accumulator is 64 bits. At 3000rpm and 16x microstepping I make
that 3 million years before counter roll-over.

Yes, just configure the spindle stepgen in "velocity" mode.

Hello Group,
I have machined or purchased the necessary parts to duplicate Sherline's
Stepper Motor Spindle Drive Conversion Kit, P/N 6500
http://www.sherline.com/6500pg.htm
I have all the mechanical parts together, and all is running well. Using the
standard Sherline controller and EMC2 with
Kent, from this descrition I gather that it's actaually only one clock,
the one running in vacuum. The other clock is just for separation from
the outside world in order to keep away all disturbances. Two questions
arise for me:
- How is the vacuum pendulum adjusted in the first place to 200 us
Dave,
I would be pleased to load the pictures up (don't expect too much,
though), but have never done so, always mailing directly. Can you give
me a link where I'm authorized to put the pics?
