This is a major upgrade mod designed to eliminate the front and back y-frame plates, along with the cheap idler bracket and wimpy y-motor bracket. The mod gives you a much stronger y-motor bracket and better idler tension. It also changes the belt path to be perfectly aligned and closer to the bed. Additionally, the y motor now sits outside of the frame area making it easier to align your belt. There are two mod versions to choose from: 1 - AZZA Z Bracing version with both types of feet. 2 - SWD2 Rear Mounted Z Bracing. I only uploaded the parts I modified and created. The rest of the parts for the Z bracing can be found here: AZZA Z Bracing: https://www.thingiverse.com/thing:921948 SWD2 Rear Z Bracing: https://www.thingiverse.com/thing:2391089 B.O.M - 2020 Y Frame Upgrade Hardware Needed: * 2x 180mm 2020 Extrusions * 22x M5x6mm or M5x8mm * 22x M5 T-Nut * 5x M5x20mm (2 for Belt Guide, 2 for Bed Belt Bracket, 1 for Idle Tensioner) * 5x M5 Nut (2 for Belt Guide, 2 for Bed Belt Bracket, 1 for Idle Tensioner) * 2x M4x10mm (for Bed Belt Bracket) - (M4x8mm should work for stock Y plate) * 2x M4 Nut (for Bed Belt Bracket) * 1x 8mm x 40mm Rod (or cut 40mm off a M8 Bolt) * 1x M3x16mm (for Idle Tensioner) * 1x M3 Nut (for Idle Tensioner) * 2x M3 Set Screws (to lock down the M8x40mm rod for Idle Tensioner) * 4x Set Screws to lock down Y rods (use original ones from your 3D printer) * 4x M3x6mm (for Y Stepper Motor) * 6x Ball Bearing 625 2RS 5x16x5 (4 for Belt Guide, 2 for Idle Tensioner) * 6x 1mm Precision Shim (4 for Belt Guide, 2 for Idle Tensioner) * 1x new GT2 belt (for new Stepper Motor position and belt routing)
