VEE CORE XY

thingiverse

A Core XY printer prototype I designed some time ago uses V-slot linear rails for the X and Y gantries and standard linear bearings for the Z-axis. A Greg Wade's reloaded extruder with an E3D Bowden adapter is employed. The pulleys are 3D printed and function flawlessly. The X and Y gantry core XY system has been tested, as demonstrated in a video. However, the rest remains untested under real-world conditions. This video showcases the X and Y gantries in action: https://www.youtube.com/watch?v=hSJEafZURIc BOM: Steppers: * NEMA 17 5x * Leadscrew Rod: * 8mm Standard Threaded Rod (Length-300mm) - 2x Couplers: * 8mm to 5mm Coupler - 2x Pulleys: * GT2 Pulley - 2x Bearings: * Bearing (16mm Outer Dia - 5mm Inner Dia - 4mm Width) - 16x Belt: * GT2 Belt >10m Length Extruder: * Greg Wade's Reloaded Extruder System * E3D Bowden Adapter + 1m Teflon Tube - 1x Nuts: * Threaded Plate (200) * M5 NUT (46) * M3 NUT (41) Bolts: * M3 HEX BOLT (Length-10mm) - 18x * M3 HEX BOLT (Length-15mm) - 22x * M3 HEX BOLT (Length-20mm) - 1x * M5 HEX BOLT (Length-10mm) - 200x * M5 HEX BOLT (Length-15mm) - 20x * M5 HEX BOLT (Length-25mm) - 8x * M5 HEX BOLT (Length-40mm) - 18x Washers: * M3 WASHER - 41x * M5 WASHER - 246x Bowden Adapter: * E3D Bowden Adapter + 1m Teflon Tube - 1x 3D Printed Parts: * Left motor angle bracket stepper mount - 1x * Right motor angle bracket mount - 1x * Left back pulley mount - 1x * Right back pulley mount - 1x * Angle bracket (100mm top back right) - 1x * Angle bracket (100mm top back left) - 1x * Angle brackets (top sides) - 2x * Angle brackets (top sides B) - 2x * Bracket corner A - 2x * Bracket corner B - 2x * Back pulley mount bracket - 2x * Back pulley mount riser - 2x * Y Axis Carriage - 2x * Carriage mount to X rail - 2x * Z stage triangle bracket - 4x * Z stage mount - 2x * PLA Linear bearing mount - 4x * Linear shaft top mount - 2x * Linear rail lower mount - 2x * Linear rail lower mount support bracket - 4x * Angle bracket (100mm) - 8x * Greg extruder support bracket - 2x * Greg extruder mount - 1x * Belt clamp - 4x * Z endstop mount to extrusion - 1x * Z endstop slider - 1x * Extrusion bracket - 16x * Pulley - 8x Aluminum Extrusion: * Profile (20 I-Type slot 5) Length-696mm - 2x * Profile (20 I-Type slot 5) Length-500mm - 4x * Profile (20 I-Type slot 5) Length-460mm - 2x * Profile (20 I-Type slot 5) Length-616mm - 2x * Profile (20 I-Type slot 5) Length-550mm - 2x * Profile (20 I-Type slot 5) Length-300mm - 2x Linear Shaft: * 12mm Dia Shaft Length-400mm - 2x Linear Bearing: * Linear bearing (12mm LM12UU) - 4x Print Settings: * Printer: P3STEEL * Rafts: No * Supports: Yes * Resolution: 0.6mm Layer Height * Infill: 30% * Notes: Used High Quality PLA. 0.8mm Nozzle Diameter.
