Shapeoko 3 Linear Rail Carriage Plates

thingiverse

_**Disclaimer:** This upgrade requires permanent modifications to your Shapeoko, some of which require drilling holes and tapping into Shapeoko's extrusions (frame) which can and will void your warranty. Proceed at your own risk._ # Shapeoko 3 on HG15 Linear Rails These adapter carriage plates are designed to convert Shapeoko's linear motion to HG15 linear rails while keeping the stock GT2 9mm belt transmission. Tight tolerances should be reached in fabrication of plates and installation of rails to ensure squareness, parallelism and prevent binding in the movement of the carriage blocks. ### TODO: * Assembly Guide * Carbide3D Z-Plus Adapter Plate * BeaverCNC Proximity Sensor Mounts ### BOM: #### Y-Axis * M4x14mm (x16) - for Carriage Blocks * M5x14mm (x12) - for Plate Joint * M5x16mm (x2) - for SO3 Belt Clips * M6x18mm (x8) - for SO3 Extrusion * M8x25mm Ultra-Low Profile (x4) - for SO3 Belt Ilders ([MISUMI #CBSS8-25](https://us.misumi-ec.com/vona2/detail/110100142270/)) * M8 Washers (x8) - for SO3 Belt Idlers * M5x25mm Standoff (x8) - for Stepper Motors; Forward position only * HGR15R 598mm Linear Rails (x2) * HGH15CA Carriage Blocks (x4) * 0.375" [High Tolerance] Aluminum Stock for Carriage and Extrusion Plates (ATP-5) #### X-Axis * M4x10mm (x16) - for Carriage Blocks * M5x14mm (x4) - for HDZ (Stepper Motor location) * M5x20mm (x4) - for HDZ (V-Wheel location) * M4x25mm (x3) - for Motor Mount * HGR15R 598mm Linear Rails (x2) * HGH15CA Carriage Blocks (x4) * 0.375" [High Tolerance] Aluminum Stock for Adapter Plate (ATP-5) * 0.5" Aluminum Stock for Motor Spacer and Mount ### Notes: Recommended to install the Y-Axis plates in the forward position to regain some Y-axis workspace. Motor pass-through bore is not required for forward position mounting. M4 threads around the edge/border of Y-Axis plate are to allow accessory mounting (i.e. homing switches). ATP-5 is recommended to increase tolerances and parallelism without requiring additional facing operations when using 6061-T6.
