Universal CNC Controller HSM 1/2003+

Does anyone know if there are active discussion groups related to
the Universal CNC Controller featured in the Home Shop Machinist
starting January 2003? I'm trying to locate parts including the
filter capacitor and some decent 135 oz. stepper motors (frame size
23). I'm building an XY table - probably 5' X 10' for a CNC Plasma
cutter.

Any suggestions would be appreciated. Especially the location of an
active discussion group where people are putting together the
electronics.

Thanks,

Bob Jacoby
