# Titan Extruder Upgrade for Anycubic I3 Mega and Prusa i3 Turn your Anycubic I3 Mega into a high-performance direct drive extruder printer with this upgrade. Watch the tutorial: https://www.youtube.com/watch?v=PVOJr0LqMk0 I drew inspiration from petrzmax's Goliathus Extruder design, but wanted to incorporate the Prusa fan duct for its exceptional airflow performance. After multiple attempts at modifying the Goliathus extruder, I decided to start from scratch and create a brand new design. ## Key Changes in this Design * Moved the hotend fan to the right side to avoid interference with the printer's X-endstop switch. * Adjustable X-endstop for precise calibration. * Integrated Prusa fan duct for improved airflow performance. ## What You Need * Titan Extruder or clone (I use TriangleLab) with pancake stepper motor. * V6 Hotend or clone. * 50x50x15 parts cooling fan. * 40x40x10 hotend cooling fan. * M3x8 screws for Nema-17 mount (2). * M3x8 screws for BLTouch (optional, 2). * M3x20 screws for X-carriage (4). * M3x10 screws (7) for hotend fan, fan duct, parts cooling fan, and adjustable X-endstop. * M3 nuts. * M3 washers (4). ## Additional Prints Required * X-Carriage: Anycubic I3 Mega Prusa i3 X-Carriage Converter. * Prusa fan duct or derivative. The Prusa Mk3 fan duct works well. ## BLTouch Installation If you want to use BLTouch, print the Nema-17 holder with integrated BLTouch mount and apply these offsets in Configuration.h: X_PROBE_OFFSET_FROM_EXTRUDER -31 Y_PROBE_OFFSET_FROM_EXTRUDER -5 Z_PROBE_OFFSET_FROM_EXTRUDER 0 **Note:** This is untested, so please report any issues. ## Assembly Instructions 1. Insert M3 nuts into the Nema-17 mount. 2. Insert M4 nuts for X-carriage into the base. 3. Assemble V6 Hotend and Titan Extruder according to their respective tutorials. 4. Mount cover and adjustable X-endstop. 5. Assemble fan duct and parts cooling fan. 6. Mount hotend fan with 4 M3x10 screws. 7. Attach whole assembly to X-carriage using 4 M3x20 screws and washers from carriage side. 8. Adjust X-endstop. When complete, calibrate the extruder expecting a higher E-steps value (around 440-450) due to gear ratio. ## Changelog ### 2019-11-23 * Redesigned base and cover for improved fan duct clearance. ### 2019-05-03 * Improved air flow of hotend cooler with redesigned base and cover. ### 2019-04-27 * Added BLTouch mount. * Included cable tie holders in the base. * Relaxed tolerances of Nema-17 mount.
