Heavy Duty Y Axis for Wilson II by lowfat

Last crawled date: 3 years ago

This is a rework of the Y axis for the Wilson 2 to make it significantly stronger. Due to the plastic ends used on the Wilson 2, any belt tension causes the motor mount to bow downward, which could cause backlash and eventual part failure. So I encorporated matsekberg's awesome design he did for the Anet A8, to use threaded rods for the belt tensioner to remove all tension from the plastic. I have also redesigned the Y-Idler and Y-Motor mounts to be significantly stronger.
You'll need two ~450mm long M6 threaded rods. You should be able to buy 1M from Fastenal for like $5. You'll also need 4 M6 nuts. Although if you have an M6 tap, I've included printable nuts. You'll need the tap to clean the threads though. I've designed the parts to use M4 screws to mount to the aluminum extrusion parts. The tensioner uses an M3 x 16mm and an M3 nut. You can use a 16T idler or a pair of F693ZZ bearings for the tensioner. The motor mount screws are M3 x 14mm.
