EndeR-Theta

The bed is able to be rotated!
I have made the mechanism the bed to be able to be rotated, but I still need to add a stepper motor mount and belt.

I managed to add the eccentric nuts to the v-rollers. But this design creates a cantilevered load on all 4 screws, so I need a top plate that can adjust the hole position to match with the eccentric nuts.

EndeR-Theta Bed Rotation Assembly
I have made a basic draft of the fully assembly to allow for the 3D printer bed to rotate. I still need to figure out a way use eccentric nuts in the design to allow the v-rollers to be adjusted for small defects in the 3d print.

Hopefully, this is the last time I post about this part.

EndeR-Theta Build Plate Rotation 02
I am redesigning the bed rotation rail to be only two pieces instead of 4, and mount to the bed rather than the frame. This allows me to save 4 screws and integrate the large pulley into the rail as a 2 piece assembly.

I have CADed a 3d printable extrusion for the v-rollers on the understand of the bed to sit on, allowing the bed to rotate, a key part of the Core-R Theta kinematic system I am modifying the printer to use.
