How to connect the 5 axis breakout board(old one) to the 1 Watt laser driver TTL input?

Depending on the model BoB, we recommend wiring it to pin 6 or CP- for your z axis since our blackTooth laser and laser/spindle hybrid, will use the Z-axis as a trigger to enable the laser just as a CNC will use pin 6 or CP- for the z-axis to enable going downwards into the material.

So if i wire it to pin 6 which is the z axis step pin on my board. what else needs to be done if i am using the mach3 engraving plugin. Can i use the step pin of the 4th and 5th axis instead?
