Hi all, I'm nearly ready to test my table now so i thought i'd get the board hooked up to mach3 and get the e-stop, limit and spindle/torch signals working and debugged.

The inputs are fine and perform as needed but i have no output to trigger the relay on the breakout board.

If i reboot the PC, the relay energises and stays on so I'm guessing the LPT port, cable and board/relay are all good.

As soon as i load mach3, the relay drops out and i cannot get it to re-energise again.

The leaflet says its on pin 9 and i have mach3 set for Output1 on pin 9 and spindle fwd/rev to #9

Any ideas as I'm stuck right now and can't progress.

Thanks
