Hypercube evolution 12mm XY modification

Thjis is a modification of the XY-gantry and motor mounts to support 12MM X and Y axis rods. The x-carriage is designed to use IGUS LME12UU compatible bearings as it is assumed that a carbon or aluminum rod will be used for the x-axis.

The Y-axis is designed for LM12LUU bearings but two LM12UUs should also work though not with the security of the circlips.

Use circlips to secure the bearings, tension the clamping bolts so you have no play.

There are three versions of the x-carriage uploaded 00, 02 and 04 The only difference is the OD for the igus bearing carrier. which is designed exact (22mm) in the 00 version, 22.2mm in the 02 and 22.4mm in 04. The reason for this is that 3d printers tend to shrink IDs somewhat the bearing still fits as the outer part of the carrier is flexible, but this has the effect that the bearings are moved slightly outboard which causes binding. So higher number means smaller bearing pitch.

To find which version you need, I suggest starting with
