I bought it with the expectation that I would have to mod it to work with the Anycubic Kobra S1 and I did. All I needed to do was make the 3 pole switch either HIGH or LOW instead of just open or closed. I then connected the wires to the printer and it worked flawlessly! It took some research and setting up but not as much as I thought it would. Review: Best Filament sensor!!! - I used to have a filament sensor that was made from an old endstop that seems to work half the time. this new btt filament sensor works everytime, it also doesnt matter what direction you feed the filament in which is a huge plus as my old one only let me feed it in 1 direction. It only took 5 min to install including the coding i had to do for klipper!!!! ## Features - High Precise: BIGTREETECH SFS V2.0 smart filament runout sensor adopts high precise photoelectric induction technology, more accurate detection, detection length 2.88mm.

It only took 5 min to install including the coding i had to do for klipper!!!! ### ⭐ Poor Quality *by F***A on February 24, 2026* I have had two of these defective right out of the box. I would not recommend. The first one the encoder would not work consistently. I spent hours trying to figure it out until I replace it and the replacement worked fine. The second unit the switch circuit would not function. Unfortunately, my current setup and programming is designed to use this product. But, I will be redesigning to use something of higher quality. ## Frequently Bought Together - BIGTREETECH SFS V2.0 Smart Filament Sensor,Filament Runout Sensor Support Klipper/Marlin/RRF 1.75mm SKR MINI E3/Octopus for Ender 3 FDM 3D Printer - BIGTREETECH HDMI5 V1.2 Touchscreen Monitor 5 inch IPS LCD Display 800×480 for Raspberry-Pi 4B/3B, BTT Pi V1.2/Pi 2 Compatible with SKR Mini E3 V3.0/Octopus/Manta M4P/M5P SKR 3 to Running Klipper --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.ni/products/547583496-sfs-v2-0-filament-sensor-filament-runout-sensor](https://www.desertcart.ni/products/547583496-sfs-v2-0-filament-sensor-filament-runout-sensor) --- *Product available on Desertcart Nicaragua* *Store origin: NI* *Last updated: 2026-08-04*
