Yes, there are 4 wires
remember that my laser is a 60W red&Black chinesse
If you pick any two, and plug a wire into the two holes (shorting out the stepper coils) you should have difficulty turning it (you might have to try a couple times to get the right two). If you then short out the other two, same thing - difficulty rotating it. If you find those pairs, itās a bipolar stepper, not a 3 phase.
I donāt get it!!! my laser need what kind of rotary? the plug is the same that my Y axis
Have you ever plugged it in? Do you know that it doesnāt work?
I connected it to the laser and it worked as the Chinese wanted me to be scammed with this. It didnāt move correctly, sometimes it responded to commands sometimes not but never in a uniform way, chaos
