Hi, ive built a few cnc machines before and have repaired many times. For some reason im running into problems wiring 1 motor for my 5 axis build. The motor is a nema 23 425oz motor that rotates the B axis of a BC head. Im using this stepper driver https://www.amazon.com/gp/product/B0...?ie=UTF8&psc=1. set at 6400 pulses/rev and 3.4 amps.

So the problem is I cant get the wiring right, ive pretty much tried about 30 wiring combinations for A+A-B+B- with the Red black blue green leads from the motor. Some combinations will allow the motor to pulse and rotate correctly, but hold very little torque, I can turn with my hand without trying. This is the main problem, is that its not holding torque. I can get it to rotates correctly with jogging, but cannot get it to hold torque. ive tried wiring the motor to the driver outside of the main wiring harness and it results the same so its not a bad wire. Ive tried a different stepper driver and its the same thing. ive tried a different stepper motor and same thing, one stepper motor with a red green blue yellow lead on it worked and held torque after initially having the same symptom before I changed the wire combination. Im basically out of ideas as ive tried many combinations for wiring. many of them worked in rotating for jogging but still held no torque.

Below are some pictures.
