thingiverse

This is a mod for the Creality3D Ender 4 printer, converting it from an H-Bot configuration to a CoreXY one. To see details of modifications, consult the "Creality Ender 4 - CoreXY Modification" pdf file, which lists necessary hardware. The list includes: * Four meters of 6mm GT2 belt (each approximately 154 cm long) * Six GT2 20 tooth idler pulleys with 5mm internal diameter * Four M5 T-Nuts for 2020 aluminum profiles * Eight M5x30 Cap head hex socket screws (DIN 912) * Two M5 nuts * Two M4x30 Cap head hex socket screws (DIN 912) * Four Spade Crimp connectors, 6.3 mm wide Over 100 hours of printing with this configuration have shown it to work fine and resolve H-Bot issues, improving accuracy and circularity. For those who want to modify the mod, CAD files are available: * Y carriage: http://a360.co/2CTvCQu * Idler: http://a360.co/2kbSuTJ * Stepper support: http://a360.co/2CUcNww Download sample print Gcode from the file section, noting that a non-stock E3D 0.4mm nozzle was used for these prints. Those who download this mod now are considered beta testers; it is expected to work but may have missing instructions or issues. Contribute through comments to improve both. Disclaimer: as with any mod, it is expected to work but if you damage your printer, you're on your own. Note: colmoni has remixed gantry parts for use in H-Bot configuration to increase rigidity; these remain compatible with the CoreXY mod. Find them at https://www.thingiverse.com/thing:2767584
