Review: Practical Addition to My Voron 2.4 Setup - I grabbed the BIGTREETECH Smart Filament Runout Sensor V2.0 for my Voron 2.4 running Klipper and I must say, it’s been a practical addition to my setup. Installation was pretty straightforward which was a relief. I was able to get it up and running in no time, and it integrated well with my existing setup. The sensor has been doing its job in reducing print errors. It's caught a couple of filament runout situations and saved me some potential headaches. The feature where it can detect not just filament runout but also breakage and clogging is something I find quite useful. It’s nice knowing that it's monitoring and will halt the print if something goes awry. One thing that stood out to me was the bilateral feeding feature. It’s a small thing but it does make the installation and filament feeding a tad bit easier, not having to discern between filament inlet and outlet. The sensor is lightweight, so I didn’t notice any added inertia to the direct-drive extruder which was a concern initially. I haven’t had to deal with false triggers so far, so the sensitivity of the sensor seems to be well-calibrated for my use. All in all, the BIGTREETECH Smart Filament Runout Sensor V2.0 has been a handy addition to my 3D printing setup. It’s been working as advertised, helping to catch filament issues early and save me from failed prints. It’s a small piece of hardware that’s added a bit more reliability to my printing process.
Review: great, avoid air prints, must have for Elegoo CC - Works great, also with ELEGOO Centauri Carbon, with an added ESP32S3 as per Utube 6JYKpZ3HX2Y

## Features

- 【Smart Filament Sensor】BIGTREETECH SFS V2.0 can not only detect filament runout, but also filament breakage, filament clogging, filament tying and even extruder malfunction. Detecting above abnormal extrusion cases, BTT SFS V2.0 will send error alerts to screen and automatically stop printing to keep you away from filament and electricity waste.
- 【Sensitive Photoelectric Filament Detector】BTT filament detection module adopts photoelectric sensor whose theoretical detection length can reach up to 2.88mm, much shorter than 7mm of SFS V1.0. Such improvement enables SFS V2.0 longer service life and higher precision in filament abnormality detection. Note: 2.88 mm is the minimum detection length for the sensor to function properly. If ‘false triggers’ error occurs, try to increase the detection length by 1mm until the problem is resolved.
- 【Bilateral Feeding】BIGTREETECH smart filament sensor V2.0 allows bi-directional feeding, which removes you from hard discrimination of filament inlet and outlet. Such upgrading enables more flexible installation and can maximize space utilization of your 3d printer! SFS V2.0 weighs only 36g, greatly reducing inertia added to the direct-drive extruder for higher printing speed and accuracy.
- 【Easy to Install】Our filament run out sensor is designed with 3 mounting holes on the back for easy installation onto your 3d printer with only a bracket. The bracket stl file can be downloaded in BTT github web: bigtreetech/smart-filament-detection-module/tree/master. The filament feeding lever serves for easy flexible filament loading. Please feel free to contact us if you have any doubts.
- 【Wide Compatibility】BIGTREETECH filament jam sensor can be mounted both on bowden extruder and direct drive extruders. It supports any motherboard with available I/O ports(Endstop, filament detection, BL touch, induction sensor, etc), like SKR MINI E3 V3.0 / SKR3 / SKR 3 EZ / SKrat / Manta E3EZ / Octopus Pro. And SFS V2.0 is compatible with Klipper, Marlin and RepRap firmwares.

## Questions & Answers

**Q: Will this work with Creality 1.1.5 motherboard. If yes, do you have documentation of needed changes to the firmware file?**
A: I don't think this will work with the silent mainboard. It doesn't have the necessary connection. You'll save yourself some pain switching to a SKR board.

**Q: I have an ender 3 v2. The board is V4.2.2 Will this plug directly into the board and is there a mount available?**
A: Yes,

**Q: What do i need to do to install on Creality Ender3 Pro**
A: I have creality ender pro 3 v2.  I needed to swap the white and black wires in the connector that plugs into the sensor.  The wire sequence was white black red.  I had issues with the signal.  I then moved to black white and red and all is good.

**Q: Will it work with octoprint?**
A: The Smart Filament Sensor plugin works, but the first time I ran and configured it, it didn't detect the movement. After clearing the data for the plugin, and re-starting it. I set my pin (GPIO 11 worked well) in the filament sensor plugin config screen, saved, then ran the test. It detected immediately after this.

### ⭐⭐⭐⭐⭐ great, avoid air prints, must have for Elegoo CC
*by I***R on September 16, 2025*

### ⭐⭐⭐⭐ Pretty good
*by R***L on March 4, 2025*

So I've purchased three. Of those three one of them was very hard to feed, and very loud. The other two are excellent. So quality control gets a little iffy at times, but they all work very well.
