Ender 3v2 Titan Direct-drive (Nema17 28mm)

[Work in Progress] Upgraded my ender 3v2 to use a titan clone and a nema 17 28mm.

Needed just the titan direct drive mount to use a spare titan extruder and 28mm Nema17 to upgrade my factory ender 3v2. Note: Used a 0.8 washer on each wheel to push the extruder motor a tiny bit off the ender frame extrusion so it wouldn't touch. This keeps the tool mount touching the x-axis limit switch and everything seems to work correctly on homing.

Print:

• PLA (Still testing, but it works well for an open printer)
• 30% infill
• 2 walls.

Note:

1. Used a 0.8 washer on each wheel to push the extruder motor a tiny bit off the ender frame extrusion so it wouldn't touch. This keeps the tool mount touching the x-axis limit switch and everything seems to work correctly on homing.

2. Suggest running hotend & extruder cables from left, in front of Zaxis extrusion. This will maintain your build volume. 

3. Titan extruder in this configuration flips the forward direction of the extruder. So either swap polarity on extruder motor cable (recommended) or apply firmware changes.

TODO:

• add that 0.8mm to this mount so that no additional parts are needed.
• Clean up cables

Also, used this awesome tool cooling shroud based on the ender 7. Works great with dual creality 4010 blowers. Good amount of airflow even from those smaller blowers. https://www.printables.com/model/158236-mbot3d-mk2-remix-ender7-style-fan-duct-with-dual-4 

Adjusted the direct drive mount to support a 28mm Nema17. Made the motor mount 1.2mm thinner. As I did not have a pancake motor lying around  (typically 23mm). Also add a cable clip over the right to keep those cables away from the titan large feeder gear. Added a second version for the filament sensor I want to add, near to the in-feed of the extruder. (Still testing this)

Note: still a work in progress
