Filament Sensor Relocation Bowden Tube Mount

Enry68 and Seafax have both explored this concept, addressing concerns about the filament sensor's placement under the Anycubic Predator control box. Some users worry that when the extruder returns to its home position, the sensor might catch on a stray loop of filament. However, there is ample space inside the box for it; all you need to do is print a part to help guide the filament through. Open the control box lid and carefully remove the bowden tube. Leave the mount in place, as removing it can cause issues with the filament catching on screw threads. Mount the original bracket supplied by the manufacturer upwards inside the box, at its original location. Attach the filament sensor to the bracket, ensuring the flow arrow points downwards. To secure the sensor, you'll need to hold down the bowden tube mount spring until the screws are in place. Route the wiring for the sensor outside the box and then carefully pull it back through the hole in the base of the control box before plugging it in. There are three different parts available to seal the hole in the lid and guide the filament towards the sensor. You can choose from a simple open cone (https://www.thingiverse.com/thing:3665598), a vertical tube to mount the bowden tube (https://www.thingiverse.com/thing:3552897), or my design that combines the two, reducing stress on the filament and guiding it smoothly from the roll towards a vertical approach to the sensor. I hope you find this solution helpful in addressing your concerns about the filament sensor's placement under the Anycubic Predator control box.
