Hi Clive, I appreciate your concern and I've taken your cautions on board. I have already built my machine and I am at the stage of determining electronics. The plans I am using call for Nema 23 motors 3.1nm and thats what I am using. I dont have the budget to buy top of the line drivers right now unfortunately. So I did go down the kit route purely because its my first build and I am learning how everything goes together - pretty much as soon as this is finished I will be making another one - it's not my "forever cnc" so to speak.

I didnt think to mention power ratings when I asked - I figured the DC current of home CNCs to be nominal and well in-line with standard audio visual power ratings. But you are right I should have thought about that. I havent bothered with a build log because I only built a Solsylva machine, they have been made and documented dozens of times online and I didnt think anybody would be at all interested.
