3 years ago The bed coupling back plate has to bridge across large spans at the the top of the dowel pin support area and the top of the antibacklash nut hole. A 45° chamfer addresses the dowel pin support bridging and a 45° slot at the top of the hole reduces the bridged span from ~6mm to 2mm. Pictures attached of the design changes and before/after print results.

Currently the parts print well from 0.4mm PLA. But some circumstances (a heated enclosure) might merit having those parts printed out of some higher-performance material.
To get there, we may need to alter the geometries of some parts that live inside of the printing chamber. This thread captures the tweaks that folks have made so far.
