Day 2

Managed to get the bearing blocks assembled and added in some gussets. They are a pain in the arse to get in, but they square the entire frame with little effort. Definitely adds a few dollars to the overall build (requires 32 T-nuts and screws, but worth the peace of mind that it's square and solid. Since I am using 3/4" ball screws, the couplings are obviously bigger than other CNC designs I have seen with acme screws, and the coupling size has interference with the piece of 8020 that it's mounted to. I have to come up with a modification to the piece of 8020 or find a smaller coupling. FEDEX expected today with the parts (linear guide rails and 3060 piece of 8020 extrusion for upper gantry) I need to go further. Also ordered all of the electronics, and should start seeing those today or tomorrow. Will start to formulate a master bill of material list. Pictures of some components for the X, Y and Z attached.
