Hi Hennies, I am in East London, probably the worst place in SA from product availability, but the hard part is over. My stepper motor size? I went a bit bigger then most with Nema 34 (12Nm) Hi torque motors, they might be an overkill, but I did not have the appetite to buy small steppers and then upgrade to larger ones later. I do believe Nema 23 would do the job as well. I was advised by my friend to buy it in a kit as it is easier and I would recommend the same. Here is the kit I went with:

I would also say if you plan to put reduction gear in play that would affect the size of motor as well, Mine will go straight on to the ball-screw's, if I went with a rack and pinion, and did a 5:1 or 10:1 reduction then Nema 34 would be serious overkill. I am using a USB Breakout Board for the Marc3 or similar G Code processor (
USB CNC Controller). You will see that the kit comes with a breakout board, but i do not like the parallel port type. If I had the cash i would go for the Ethernet Smooth Stepper, but that is not an option for now. The cost for my build is a bit high, but then I do have a couple of luxury items in it, I am sure I could cut the cost in some areas by a large margin if I chose to build /weld. How much are you planing / hoping to spend ?
