For people searching in the future, here’s what worked for me. I switched the wires in the wiring harness of the LDM extruder. If you look at the wiring harness, it has slots for eight wires, only six of which are used. There are four used on one side of the harness and two used on the other side. Leave the side with two wires alone.
With the side with four wires facing up and the wiring harness pointing to the right (so the extruder head is to the left), the order of wires in order from farthest away to closest to you should be pink/red, blue, green, black. See photo below.
