General Mach Discussion / Breakout Board relay failure
« on: February 25, 2012, 11:24:04 AM »
Hi all,

i ve wired a breakout board to my pc's parallel port.
here is  wich board it is . http://www.dhgate.com/cnc-router-mach-cnc-interface-board-for-pc/p-ff8080812d2c40c9012d36d677d34296.html

It has 2 relays on board.
My problem is  , when ever  any axis starts to move  , my new board  sets on  the relay. after the move ends , it releases the relay
I have two spindles on my machine. I want to use the relay to select wich spindle i would like to use.

Is there anyone have any idea ?
thanks alot
