Laser Interface & G540

[bdring]

I tested the Laser Interface PCB with the G540 tonight. I worked fine. The disable circuit even works. You need a little cable to run the stepper terminal blocks into the D connector for the G540. It is only 7 wires...step (2,4 & 6) and dir (3,5 & 7) for each motor and ground (25). You also need to run one one the motor enables to terminal 10 of the G540 terminal block. I will make a schematic soon.

For the next revision you ought to put a 2x13 header on there so you can just run a ribbon cable to the G540.
