Hi George.

The jaws require a pneumatic system to operate, so if your lathe has that system fitted, you would need to attach a compressor. Mine has a manual chuck, so I've not looked into that.

The only drawings I have came from a copy of one of the manuals, so you should have that now.

I'm using a Planet-CNC Mk2/4 board to control the original stepper drivers etc, wired up to the original homing and limit switches. It has very limited inputs, so this does mean you lose the use of a lot of the front panel buttons, but I have managed to get the jogging ones connected again.

I'm having problems with the Planet-CNC software, as I think it's designed mainly for routers rather than lathes, so I'm also looking at the Eding controller, in case the Planet-CNC one falls through. Both of these use their own software, so I've not investigated Mach3 for this machine.

Adrian.
