Creality Ender 3 Pro Dual Z Axis Bearing Block Assembly Retention Block Upper
Description
<b>Creality Ender 3 Z Axis Bearing Block</b> This is a modification for the ender 3 creality dual z axis drive kit or any other dual z axis drive kit meant for the ender 3. This kit is meant to be used to lock the lead screw in place while being driven by a belt by an overhead motor driving a synchronization belt linking the two drive screws together. ------------------------------------------------------------------------------------------------------------------------ <b>Motivations</b> This design was instigated by the rampant z-banding present in most cheap bed slinger printers that use pom wheels for the z-axis. The cheap lead screw assembly and poor alignment often lead to heavy z-banding and gantry sag resulting in poor print quality and inconsistent z-hop. The bearing block with an overhead belt drive system and Oldham couplers eliminates all problems plaguing these printer topologies. The overhead drive assembly ensures only two points of contact on the lead screw and complete stability of the drive position of the lead screw. No more coupler issues, no more coupler shifting, no more misalignment. All z-banding artifacts should be addressed with this drive system. The design uses 608 bearings to eliminate axial movement and needle thrust bearing sto eliminate z axis movement. The lead screw is locked in place providing a true bearing block for the z-axis drive.
