Titan Aero Upgrade for Original Prusa i3 MK2(s)

thingiverse

It appears that you've provided a detailed assembly and configuration guide for an E3D Titan Aero extruder on a Prusa i3 MK2S printer. The instructions cover installing the motor, linear bearings, PINDA probe, heatsink fan, blower fan, and heater block, as well as configuring the firmware to account for the 3:1 gear ratio. Here's a summary of the steps: **Hardware Assembly** 1. Install Nema-17 short body motor on left side of aero mount with wires toward back. 2. Mount titan on right following instructions at https://wiki.e3d-online.com/wiki/Titan_Aero#Assembly_Steps. 3. Install cartridges in heater block opposite of what is shown on e3d, so wires exit other direction. 4. Check clearance of filament gear in slot and between linear bearings on back of X-carriage. 5. Insert PINDA into pinda mount and add two screws and nuts loosely for now. 6. Screw pinda mount onto X-carriage, lining up arrows, using M3x25, nut optional. 7. Mount heatsink fan onto heatsink according to e3d instructions and route wires next to PINDA wire in channel. 8. Mount blower fan into blower mount by tipping outlet into mount and rotate to snap in top. 9. Attach blower mount using ends of the two M3x20 screws holding the aero mount, outside of the existing nuts. 10. Route blower wires alongside the motor wires in channel. 11. Angle the heater block so the nozzle is nearest the blower outlet and clamp screw is nearest the PINDA. 12. Add e3d silicone sock over heater block. **Firmware Configuration** 1. Change extruder steps to account for 3:1 gearing using `M92 E418.5` in start g-code (or `M907 E900` if using e3d slim motor). 2. Perform an extruder calibration to adjust value as necessary. 3. Commit the change to eeprom using `M500`. **Software Notes** * The firmware configuration should be done on a computer with Pronterface or Octoprint terminal installed. * If you're using a 0.9 step motor, you need to double the number in the extruder steps command. **History** * V1-V5: beta test versions to get kinks sorted out. Many thanks to spid303 for testing. * 12/13/17: I added the step files for your hacking pleasure. This guide is quite comprehensive, covering both hardware assembly and firmware configuration. However, it's always a good idea to double-check the instructions and make sure you understand each step before starting the build process.
