Losing steps/position, again

[ngwagwa]

This appears to be getting complicated.
Out of the stepper motor I have Black - White - Orange - Red - Blue and Yellow
Blue and yellow are not connected to the cable
White is connected to the yellow in the cable

I can't be sure if these are the same in the cabinet but in the cabinet I have the following pairs
Read and Yelow
Black and orange
These are all labelled X

The Stepper motor is Sanyodenki 103H7124





So by my reckoning I I am connecting to the taps on the stepper?

It's simple to test just check the resistance between the three wires of each coil. One pair will be double the resistance of the others. These two are the ones you want for each coil.
Do the same for the other coil and you have found your 4 wires needed. Just leave the others disconnected but terminated for safety.
