Hi Guys and greetings from sunny Birmingham, UK

I'm hoping one of you will have some vital information I need.

A good while ago, I inherited the aforementioned machine from my Father-in-law, since died, because it frightened him some - it was making a funny noise and smell.

A brief investigation at the time indicated lots of heat on the control box and an intermittent operation of the steppers. I didn't have any time to go any further, so I oiled it up and packaged away.

Now I've retired, I'd like to get it out and sort it .. ..
I don't fancy trying to diagnose and repair the control box, so I've bought a Controller board and motor driver boards to build my own system.

I have a problem because aside from some Chinese hieroglyphics I don't understand, there are no markings on either steppers or spindle motor. I think the spindle motor is likely to be 300Watts and there is a code on one of the steppers which could mean 1.8deg (200 steps) and 2 amps.

Does anybody have a suggestion of what voltage to supply to the motors please ?

Thanks

S
