Solidoodle Y-Axis Direct Drive

thingiverse

This is My Design for the Conversion from a Belt Driven Drive to Direct Drive for the Y-Axis on My Solidoodle 3. Items Needed: (4) 608ZZ Bearings (1) 8mm Shaft (1) 5mm to 8mm Coupling M3 Screws and Nuts, I Had M3x25's On Hand So That's What I Used. I Was Also Upgrading to GT2 at the Same Time, So I Had 8mm Diameter Pulleys As Well. I'm Satisfied with It So Far. The Frame Actually Flexes Quite a Bit, but My Circles Are Circles, so The Goal Was Accomplished. It Might Help to Have a Spider Coupling Instead of the Helical That I Used. Instructions This is A Fairly Simple Modification to Do. The Motor Mount Uses the Existing Holes for the Old Y Motor Location, Which Means It Has a Good Range of Adjustment for Aligning Everything. The Two Interior Pillow Blocks and the Side Block I Drilled Holes to Mount Them. How You Line Everything Up Is up to You, I Measured Some and Eyeballed Some. Some of the Files I Have Updated Just a Tad to Make Them a Bit More Aesthetic than My Purely Functional Ones Pictured. Constructive Criticisms, Comments, and Questions Are Welcome.
