I have an old torcam cnc lathe that im
trying to get running using turbo cnc.
it has a parallel port interface to a breakout board
with a spindle relay and a jog keypad.
machine powers up ok and steppers lockup
but cannot jog machine with either computer or
keypad.
would there be a enable pin for a charge pump?
or would i need to change the breakout board.
any ideas
thanks
