THIS DOES NOT WORK
I'm going to try to make a smartcore with 1/2inch emt. It's dirt cheap and I'm convinced after building the MPCNC that conduit is a great choice for this kind of stuff. One corner is done and I'm going to be working on the other parts as I have time. I already have two printers though and I'm expecting a new kid soon.... so don't expect too fast of updates..
Please feel free to participate if you want.
