UM2 Volcano Direct Drive Head with BMG Extruder

Edit: Update 16.01.204, my UltiMaker2 is still in use.

• Added Creality Touch mount in favor of the optical sensor (better accuracy)
• Changed all Brass inserts to 4mm to fit a M3x4mm curled nuts with an OD of 4mm (works fine for me)

This is a lightweight Volcano Head for an Ultimaker 2 using a Volcano Hotend and a Direct drive BMG Extruder including a ADXL345 for InputShaping using Klipper.

The Linear Slides are fixed used curled M3x4 knurled nuts and M3 screws from the top and bottom of the head. The Extruder is as high to be above the case not causing any colisions.

M3x4 knurled nuts and M3 screws are used in this design.
