Direct drive bondtech CR-10/CR-10S with drag chain and cam

thingiverse

It looks like you're trying to provide a detailed guide for modifying a Creality CR-10S 3D printer with direct drive and Bondtech. You've included various STL files, assembly instructions, and notes on materials and printing settings. To provide a helpful response, I'll break down the content into sections: **Direct Drive Assembly** * The direct drive is designed to work with the Creality E3D clone. * There are two versions: one with metal and one without. You recommend using the version without metal for weight reasons. * The assembly includes supports for the direct drive, drag cable screws, webcam fixation for C270, and a direct drive v1 (now obsolete) assembly guide. **Drag Chain Fasteners** * For the drag chain fasteners on the motor side: * You need to assemble the "support engine" and "drag chain support engine" STL files. * Use M3 x 8 screws for the bolts listed in "drag chain support engine". **Motor Side Fasteners** * For the drag chain fasteners on the direct drive side: * Assemble the "support for drag and cam", "arm cable drag chain", and "support cam base" (optional) STL files. * Use M4 x 12 screws with bolts inside "support for drag chain and support cam". **Printing Notes** * Avoid using PLA or use reinforced PLA after baking. Instead, prefer PETG or ABS. * Add a stabilization bar to improve the printer's stability. **Edits and Updates** * There have been several edits and updates since the initial publication, including: * Adding a piece to patch the wheel support (edited 11/01/2019) * Increasing the curvature of the guide for cable preservation (published 30/01/2019) * Redesigning the direct drive model to simplify printing and reduce bending (edited 12/03/2019) * Adding a support for an optical filament detector with different height options (edited 22/03/2019) * Adding a new optical end-of-filament detector with mechanical action (edited 24/03/2019) **Stab Bar BLTouch** * Update the X_PROBE_OFFSET_FROM_EXTRUDER and Y_PROBE_OFFSET_FROM_EXTRUDER settings to -23 and -25, respectively. Please let me know if you need any further assistance or clarification on these instructions.
