Tenlog Hands 2 Y Axis Linear Rail Conversion

prusaprinters

<p>This is the in-progress development for a linear rail conversion for the Y axis of the Tenlog Hands 2 IDEX printer. My biggest complaint is the fact that v roller wheels are used on the Y axis, despite the X axis using an MGN12 rail so I designed a conversion. This is designed to keep the bed at roughly the same height as stock and re-use the factory leveling hardware. No endstops have to be moved. The belt system is also unchanged, just longer bolts are required. Rail alignment tool file provided. <strong>At this time the implementation of this conversion is untested, so install at your own risk.</strong><br><br><strong>BOM:</strong></p><ul><li>30x M3 SHCS, 10mm long</li><li>24x M3 T-nuts for 2020 extrusion</li><li>2x M3 SHCS, 6mm long</li><li>2x M4 Button Head Cap Screw, 25mm long</li><li>2x M4 Nyloc lock nuts</li><li>2x MGN12 Linear Rails, 350mm long</li><li>4x MGN12C Blocks (These are the <strong>short</strong> blocks)</li></ul><p><strong>SOURCING:</strong></p><ul><li>Fasteners: McMaster or Bolt Depot</li><li>Rails: Aliexpress, CNA Mechanical Parts Store</li></ul><p>M3x10 SHCS are used to fasten MGN12C blocks to Bed_Carrier. M4 button head screws and nyloc nuts are used as the new belt retaining bolts, with the nut used to lock the screw in at the correct height from the Bed_Carrier. M3x6 SHCS are used to fasten Endstop_Flag to Bed_Carrier (must be on <strong>right</strong> side of printer). The holes for the M4 button head screws will have to be tapped, as well as the screw holes to retain Endstop_Flag. The factory end plates will have to be replaced with End_Plate. I realize Bed_Carrier is severely overengineered and probably heavy, if you have an idea for a lighter design feel free to modify the provided STEP file. Bed_Carrier will be machined from aluminum for my application, but if you want to 3D print it instead I've included a .3MF and .gcode file.</p>
