Can one use a two wire touch probe with a shopbot? Looking at the connection diagram in the shopbot documentation, it looks like the 5V connection is really only providing power for the led's, while a 2 wire probe is really only providing open/close (normally closed) just like the z-plate. Would the proper way to connect this thing be to connect the red wire of the probe to the plate and the black wire of the probe to the shopbot ground just like the z-zero plate?
