I have an old MaxNC MaxPath42 with Lin Engineering 5718L 3D 6 wire hybrid stepper motors, which have been wired as 5 wire unipolar motors.

Lin Engineering built this motor specially for a manufacturer of flexible hoses from which MaxNC bought them.
Lin Engineering can not give me the manufacturer's name, nor can they give me the motor specs as it is a proprietary item and MaxNC has gone out of business.

The X axis motor has blown two TIP120 capacitors so far and to correct the problem, I need the motor specs.

Can anyone help?

No one seems to have info on these motors so I'm going to lock this post
