Z axis install on K40

Machine: K40

Board: Cohesion3D LaserBoard

Firmware: I have a new board and I’m using whatever it came wit

I’m very new to this stuff and am very unsure of what I’m doing.
If my questions seem stupid please accept my apologies.

Problem/ Question:

Does the wiring look correct up to this point and
where do the last 4 wires make connection to the board?

1st pair go to driver B+ and B-
2nd pair go to driver A+ and A-

VCC go to DC power supply #5 COM
GND go to DC power supply #7 V+
PUL+ DIR+ ENA+ are all jumped

These last four go to Cohesion #D Laser board

Oh god. Stop. You don’t wire the digital inputs for STEP DIR EN of an external driver to the high voltage outputs of the motor driver. That’s how you break expensive things.

This is how you connect the external driver to the laserboard. Assuming you are with Dan Janes, I believe he ordered the signal cables you need in his first order, not the more recent one with the external driver.
