I have the Blue and White 50W Chinese laser. Recently the Y axis NEMA motor starting having fits starting and stopping. I connected the rotary unit that runs off the same stepper driver to see if the controller had any issues. It doesn't and I had zero issues engraving 20 glasses. So I am guessing it is either the NEMA 23 that runs the Y axis or the wiring for it. I would like to replace the motor but I am having a hard time finding either specs on the one I have or a replacement. Any help would be greatly appreciated. Below is information I got off the existing stepper motor.

Type: 23HD450Y 2S
FH160315 Smooth
Stepper driver JMC 2M542-06

It is a dual shaft with 4 wires.

Thanks,
Jim
