Ok.... It's Chinese, works well, identical on all 3 axis.......
Question is who's is it and what's a good make to do a complete swap with if it goes tits up ?

Anyone any ideas?

You need to find the following things:

The A and V at which the motor is driven on that machine.

So find the PSU and see what V and W for all motors. Then find the stepper drive and see at what A it drives the motor.

Thats all.

Its a nema 23, looks to be about 70-80mm long so will be between 1.8 and 2Nm.
Its 4 wire, so check the driver to see what the current is set to and then you will be quite close.
