Update 07.04.2019 Titan Upgrade for Prusa i3 MK2. Enables E3D Noctua 40mm Hotend. Shroud looks funny due to design constraints. Works fine after installation. Remark 09.01.2018 Use a heat sock with the heater block to prevent thermal runaway when using a fan (https://e3d-online.com/v6-socks-pro-pack-of-3) Update 11.05.2017 Updated assembly instructions for easier upgrade. Update 25.04.2017 Extruder mount v1.1 with enlarged hole for adjusting gear play. All parts in STEP format available for download (download as .rar). Update 12.03.2017 Fan mount V1.2 - Increased air flow throughput. Fan mount V1.2x - For bigger fans GB1205PKV1-8AY. Enjoy the E3D Titan geared extruder with your Prusa i3 MK2. Increase force on filament by a factor of 3 to brute force any material without clogging. Print with a tiny 0.15mm nozzle for outstanding detail quality. For more information, see http://e3d-online.com/Titan-Extruder Download - Print - Assemble - Update Firmware (optional) - Print better! We love seeing this project getting so much interest! Thanks for the fun conversation! Feel free to leave comments, ideas, and proposals for improvement. This version is installed on our Prusa i3 MK2. It fits and works perfectly. You'll need: Prusa i3 MK2 E3D Titan Geared Extruder THIS (the fan shroud) Cable ties, M3 nuts, and hex-socket screws (M3x40, x20, x16, x12) 1-2 beers (optional) Optional nozzle fan mount for axial fans 40x40mm for better visibility of the nozzle.

Usage of original parts: E-motor PINDA sensor Hotend fan Nozzle fan Bearings / bearings fixation (cable ties) Belt fixation Usage of standard parts: E3D cooling fan shroud (the blue injection molded) Can also be printed (it’s included) Metric screws and nuts M3 Keep original positions X Y Z As less restriction on x-axis traveling distance as possible: 240mm instead of 250mm More possible when omitting the extruder mount. Custom Section Current available versions: Extruder mount - V1.0 X-carriage - V1.0 Radial fan mount - V1.1 (improved printability) Radial fan mount - V1.2 Increased air flow throughput Radial fan mount - V1.2x for bigger fans GB1205PKV1-8AY Axial fan mount - V1.0 Tightening knob - V1.0 Indicator - V1.0 All downloads will be updated to the newest versions. Firmware: Please check the comment section as some encountered issues with the provided firmware 418.5 (gear ratio) Direction of extruder: INVERT_E0_DIR true --> INVERT_E0_DIR false (gear) Unload filament speed F7000 --> F3000 (motor speed) - not really necessary, but works better for my MK2 Renamed all "fpos_t" to "fpost" to avoid errors when compiling see http://forums.reprap.org/read.php?146,691608,724250#msg-724250
