RE: [CAD_CAM_EDM_DRO] Re: Monarch 10EE retrofit

Hi Marcus,

The best approach if you want full featured CNC for your lathe is MACH3, a
PC running at least a Gigahertz and some sort of parallel port interface
module that let's you connect to a couple of stepper motor drivers. The
drivers will need a power supply for the motors.

If all you want to do is threading at a minimal cost, at the E-Leadscrew
group we're working on an Electronic Leadscrew where the parts cost is
definitely under $150 including the micro-stepper driver for a 3Amp 55V
motor. A 10" lathe may well require a larger motor although if all you need
it for is threading then that may not be an issue. I've used it to cut both
imperial and metric threads on a 7" homebuilt Gingery Lathe. Have yet to
add the stepper motor interface to my SB Heavy 10L.

Check the group archives. Lots of folks have done this.
