Upgrading Your Ender-3 Pro: Filament Sensor Mount for MiniPad

If you own an Ender-3 Pro and want to enhance your printing experience, consider adding a filament sensor. This simple upgrade can save you from potential print failures due to running out of filament. In this post, I’ll guide you through mounting the sensor that comes with the MiniPad for Ender-3, using an original design tailored specifically for the Ender-3 Pro.

Why Add a Filament Sensor?

A filament sensor helps monitor your filament usage in real-time. It detects when the filament runs out and can pause your print, allowing you to replace the spool without losing progress. This feature is especially useful for longer prints or when using large spools.

Materials Needed

Filament sensor from the MiniPad

Mounting screws (3mm x16mm not included)

3D printed mount (see link below for the design)

Basic tools (screwdriver, etc.)

Step-by-Step Guide

Print the Sensor Mount

Download the original design for the filament sensor mount here. Make sure to print it in a sturdy material like PLA or PETG to ensure durability.

Prepare the Sensor

Remove the filament sensor from the MiniPad packaging. Familiarize yourself with its connections and orientation.

Attach the Mount

Position the 3D printed mount on the designated spot on your Ender-3 Pro.

Secure the Sensor

Insert the filament sensor into the mount and secure it using the provided screws. Ensure it is snug but not overly tight to avoid damaging the sensor.

Connect the Wiring

Follow the wiring diagram provided with your MiniPad to connect the sensor to your printer's control board. Make sure all connections are secure.

Test the Setup

Once everything is mounted and connected, run a test print. Monitor the sensor's functionality by simulating a filament runout to ensure it pauses correctly.

Conclusion

Adding a filament sensor to your Ender-3 Pro can significantly improve your printing reliability. With the original mount designed for the MiniPad sensor, you’ll have a seamless installation that enhances your printing setup. Happy printing!
