      Functional real-world build with RM2-2RS bearings in routed V grooves on phenolic resin rails (lab countertop scraps) and NSK 25mm linear rails/trucks. Plasma cut steel and stainless steel components - several with easy bends. CNC routed Columbia Purebond hardwood plywood and resin components. 2GT belts on OpenBuilds smooth idlers with 688 bearings. 1/2in ACME lead with Delrin anti-backlash nut. NEMA 17 on X/Y and NEMA 23 for Z. Feeds and acceleration, despite weight in motion, exceed those required for 3D printing. Pictured with temporary wood bed supports, which will be replaced with resin. Build is pretty much complete, except for deciding on a bed and waiting for ordered spring coil to go over the vinyl tube for wire management. Marlin 2.x on SKR v1.1 controller with DRV8825 and TB6600 for Z.

    Reason for this Build

    Constantly having to replace junk linear motion components on FFCP, D6, and others. Wanted something less fragile, with larger bed, and low maintenance.

    Inspired by

    Lack of maintenance on plasma tables with RM2 bearings.
