Look on the back of the keyboard for microchips, or on a board that the
keyboard connects to. Google the numbers to see what they are.
I'd thought about hoking up the keyboard from the Anilam Crusader 2 system that
was on my big mill. Shouldn't have been too difficult since a cable went from

That is the pinout between the control and the drive. The drive doesn't
have any direct encoder input.

Is that the pinout between the motors and the drive? Or is it the
control signal to the drive?

LinuxCNC has all the features you need for servo control built-in, you
really just need a dumb motor driver, t
I would have said it was more incorrect and misleading than out of date.
And the fellows claim of DNC as being a "feature" is laughable. I work with
Fanuc controls all day, DNC isn't a "feature" it is a band-aid work-around for
the controls limited memory, and a huge pain in the ass to have to

In the Dandenong ranges, at an altitude of 600', on the outskirts of
Melbourne, Victoria. (38°S) The 120 km/h winds are not so common here;
the last time I experienced them was 27 years ago
