I pulled the transformer out of the panel hoping to find some specs. printed on it, but unfortunately nothing.

It turns out to be Lintron & from there website I have the following specs: 160VA with an OD of 115 & height of 45. Weight 2Kg

The AMC driver board has +37VD printed on it beside a fuse along with +5VD in other places, so I'd guess a tapped voltage of +37V. Current I don't know.

I'm starting to think that as I'm not 100% sure what I'm doing (more like 50/50 at the mo. :lol:) it might be best for time versus cost, to go for a one box solution.

Trawling through other parts of the forum I see Roy at DIYCNC has a good name. What about this as a 1 box solution?
http://www.diycnc.co.uk/html/cnc_systems.html The 3 axis System without motors Code SYS43CFK £252. I see the supply voltage is 27V though when the steppers will take up to 90V :confused:.

I hadn't clicked that the supply voltage was proportional to motor speed & torque. Holding torque would be more important to me than travel speed. I aim to be cutting hardwoods, MDF & plastics in this machine but I don't know what kind of torque I need. The spindle power is usually my limiting factor as I will probably install a Kress 1050 unless someone can suggest an alternative. The Kress can burn through brushes rightly with a 6mm cutter :twisted:. With the Kress speed control for me would be unimportant as I normally set it manually at the start of each process. I just need an output that I can use to switch the spindle.
