E3D Hemera + BLTouch + Linear Rail + Filament Sensor for Ender 3 / CR20-Pro (Modified X-Axis)

Hello people,

in this project I have installed the E3D Hemera Hotend on a Creality CR-20 Pro / Ender 3. In addition, the x-axis was upgraded with a Linear Rail System. Furthermore the BLTouch of the system was moved accordingly.

As a filament sensor, the original Prusa IR filament sensor was integrated into the system, which can be purchased at the following address:

These modifications result in a solid and well-functioning direct drive system, which I have now been using for a long time and which works reliably.

The conversion is a remix of the following link:

A detailed manual will be published soon
