Supported Rails SBr12 Upgrade

I have just upgraded the unsupported SC12UU bearings and linear rails to SBR12 supported rails. The old rails worked fine but had some flex in them because of the length. At the same time I had to re-mount the Nema17 stepper motors and the electronics.

The new 600mm long rails still in there plastic wrapping. I think these bearings can be removed from the rails without lousing all the ball bearings but I didn't risk it.

The two conversion plates made from 38mm x 5mm x 100mm tee section aluminium. I like using CAD but a pen and paper works just as well. All holes were just marked out, centre punched, drilled with a pistol drill and tapped by hand.

The new X axis rails assembled showing one of the stepper motor mounts and the M6 lead screw and its nut.

The X axis has a total travel of 500mm.

Watch my YouTube video to see a time-lapse of the disassembly and re-assembly and for other information.
