Hi. I want to use the capabilities of my Duet 2-Bad levelling using multiple independent Z motors. My z axis has 6 guide rails. The bed size is large (800*400mm). The instructions say: You should not use 4 leadscrews with a bad that is rigid enough to resist twisting strongly (https://duet3d.dozuki.com/Wiki/Bed_levelling_using_multiple_independent_Z_motors#main) I have 4 nezavisymykh motor are used for axis Z. As me do fastening, kotore not will too rigid and not will break under twisting bed?
