Hypercube Shaft Endstops

thingiverse

These are simple rings that clamp onto the shafts of a CoreXY mechanism to set travel limits when using StallGuard feature of TMC2130 drivers instead of limit switches or other endstops. Print two of each to make a set suitable for a Hypercube 300, which uses 10-mm carbon-fiber tubes on X and 8-mm steel rods on Y. Use M3x6 screws and M3 nuts to secure the two halves to each shaft. Modify and re-render OpenSCAD files if you need different diameters. The X-axis endstop is 10 mm in diameter, which matches the dimensions for X-axis carbon-fiber tubes specified for the Hypercube 300. The Y-axis endstop is 8 mm in diameter, matching the dimensions for Y-axis steel rods on that printer model. Change and re-render OpenSCAD files if you need different diameters.
