Connecting C3D laserboard to LightObject Z-table

Machine: K40 (blue)

Board: C3D laserboard

Firmware: Smoothie

Problem/ Question: I’ve gotten my LightObject Z-table working with my C3D laserboard (LB) running under Lightburn. I thought I’d share how I wired the Z-table to the laserboard. It was complicated due to the fact that the laserboard’s markings for the 4 stepper wires are B2 B1 A1 A2 while the wires on the stepper motor from LightObject are A+ B- A- B+. If there’s a translation on the web somewhere I failed to find it! Anyhow, below is a picture of the final wiring:

motor-orange goes to LB A1
motor-yellow goes to LB B2
motor-brown goes to LB A2
motor-red goes to LB B1
