Hi,
I'm starting to collect parts for a new cnc gantry router. I'm looking at about a 4' x 6' table. I picked some shaft supports for 3/4" shaft on ebay and was wondering how much (if any) deflection could be expected if I used 3/4" X 48" shaft supported on each end for my X axis on the gantry and closed bearings? The Y axis will be 1" on rails and open bearings. Most of the time it will be milling mdf or plastic.
Thanks,
