RE: [CAD_CAM_EDM_DRO] Help implementing spindle & coolent on/off

Ed,

To control 4 axis and spindle/coolant on/off from a single parallel port I
would highly recommend the PMDX-120 Parallel Port Accessory Module. It has
the relays built on to the board and will drive 4 axis. It works just fine
with Master5. Check out http://www.pmdx.com/PMDX-120/index.html for a
picture and description of this board.

I have no connection with PMDX other than being a very satisfied user.
