Hey: It has been a while, and I am looking into building a similar setup, with some extras. Did you have any success on the build?
I am planning to use 608 bearings on either 1inch square aluminum tubing, or on 1'' EMT conduit like the MPCNC. I plan to build the whole system on a gantry style similar to a CNC router that doesn't move the bed. Thoughts??
