it is unfortunate the current design dosn’t lend itself to add additional support to stiffen the inner x or y rails that attach the Z axsis. if one of the z Aziz rollers that attach the x or y axsis were open either above or below if you could add support to stiffen it (think I beam type structure). In theory, it could then be as large as you could dream up. To start i’ll probably build a 3×3 outer dimension just to get the electronics going and test a support design for the outer rails.
