Building a minimill with Nema 23. Using a multimeter, I found all the correct pairs of wires. Wired it up. Got green lights on two of the steppers but third one is red? All wired the same. after a few seconds, stepper lights/power go off then back on? I disconnected all but one motor and it does the same. Powersupply is the 24/ 14.6 Meanwell.
