Thanks fo the welcome

I have been reading though the forum and am beginning to realise that i may be going down the many roads that lead to dead ends that many others and stumbled upon. Ok thankfully I have not as yet built the machine so can start smaller. Here is what i intended to build :-

Mill for Wood and aluminum

X axis = 600mm
y axis = 600mm
z axis = 300mm

I have bought these motors Astrosyn MY103H702 (they are in the post I hope). I read you have a set and were going to test them, did you get round to it? I was going to post a question about them on the original thread. I need to figure out the power supply for them, can you help?

so that is the basic outline. My hobby budget is very limited and I am happy to change my plans just get my teeth into cnc.

Too big an idea for my driver? could you suggest axis dimensions?

Thanks for your interest and knowledge

Tony
