Customer Questions & Answers
-
Question:
What is the BIGTREETECH SFS V2.0 Smart Filament Runout Sensor?
Answer: The BIGTREETECH SFS V2.0 is a bi-directional photoelectric filament break sensor designed to detect filament runouts or breaks in 3D printing applications. It ensures continuous printing by signaling the printer to pause or stop when the filament is insufficient. This technology is crucial for preventing wasted material and time, ensuring that your prints are completed without interruption. For instance, it is particularly beneficial for large prints that could take hours, allowing users to avoid starting over if a filament failure occurs. -
Question:
How does the bi-directional feature work in this sensor?
Answer: The bi-directional feature means the sensor can detect filament movement in both directions. When the filament runs out or breaks, the sensor immediately communicates this status to the 3D printer's controller, allowing it to respond accordingly. This functionality provides more reliability compared to unidirectional sensors, as it can detect filament issues regardless of how the filament is being pulled. This is particularly effective in setups that use a Bowden tube system, where filament paths can vary. -
Question:
Is the BIGTREETECH SFS V2.0 compatible with other 3D printers?
Answer: Yes, the BIGTREETECH SFS V2.0 is designed to be compatible with various 3D printers that use 1.75mm filament, particularly those utilizing the SKR Mini E3 V3.0 board. The sensor can likely be adapted to other boards with appropriate wiring and firmware adjustments. This versatility allows users to enhance their existing setups or integrate it into custom builds, making it an excellent choice for both hobbyists and professionals looking to improve printing reliability. -
Question:
What type of filament can I use with the BIGTREETECH SFS V2.0?
Answer: The BIGTREETECH SFS V2.0 is specifically designed for use with 1.75mm filament, accommodating various materials such as PLA, ABS, PETG, and TPU. This compatibility ensures that users can utilize a broad range of materials according to their project requirements. By implementing this sensor, users can seamlessly switch between filament types without compromising the print's quality or reliability, making it a flexible addition to any 3D printing toolkit. -
Question:
How do I install the BIGTREETECH SFS V2.0 sensor?
Answer: To install the BIGTREETECH SFS V2.0 sensor, you will first need to locate the correct position on your printer for optimal filament flow detection. The sensor should be placed before the extruder in the filament path. Connect the sensor wires to your 3D printer's control board according to the provided wiring diagram. After physical installation, you may need to configure settings within your printer’s firmware to ensure it recognizes the sensor. This process enhances printing reliability by enabling immediate response to filament issues. -
Question:
What are the benefits of using the Smart Filament Runout Sensor while printing?
Answer: Using the Smart Filament Runout Sensor adds significant reliability to the 3D printing process. It minimizes the risk of failed prints due to filament breaks or runouts, saving material and time. This sensor is especially beneficial for long-duration prints, allowing users to manage their printing jobs without constant supervision. Additionally, for projects requiring high precision, being alerted to filament issues early on means users can make adjustments immediately, enhancing overall print quality. -
Question:
Can I use multiple sensors on one 3D printer?
Answer: Yes, it is possible to use multiple BIGTREETECH SFS V2.0 sensors on one 3D printer, provided that your printer's firmware supports multiple filament detection inputs. This setup can be particularly useful for users working with multicolor or multi-material prints. By integrating several sensors, you can monitor each filament path independently, ensuring that any issues are immediately flagged, thus enhancing overall operational efficiency in complex printing projects. -
Question:
How can I calibrate the BIGTREETECH SFS V2.0 sensor after installation?
Answer: Calibrating the BIGTREETECH SFS V2.0 sensor involves ensuring it correctly detects filament movement and responsiveness. After installation, you can perform a test print with the filament loaded through the sensor. Observe the sensor's behavior when the filament is pulled and released. It may also require adjustments in the firmware settings on your printer, where you can fine-tune sensitivity levels for optimal detection. Proper calibration ensures peak performance and reduces false signals. -
Question:
Where can I buy the BIGTREETECH SFS V2.0 Smart Filament Runout Sensor in UK?
Answer: You can purchase the BIGTREETECH SFS V2.0 Smart Filament Runout Sensor at Ubuy. They offer a reliable selection of electronics and 3D printing accessories, making it easy for customers in UK to find and order this sensor with confidence.

BIGTREETECH 3D Printer Accessories Editorial Review
The BIGTREETECH SFS V2.0 Smart Filament Runout Sensor has generated a mix of reactions from customers, showcasing both its strengths and notable drawbacks. Many users have praised the sensor's easy setup process, particularly when integrating with popular systems such as Raspberry Pi and Marlin firmware. The sensor is designed specifically for 1.75mm filament, which was a point of confusion for some users who needed alternatives for different filament sizes. In practical use, the sensor reportedly enhances the operation of various 3D printers by stopping the printing process in case of filament runout or other issues like clogs, thereby preventing potential print failures. Several users have expressed satisfaction with its reliability, especially when used with Klipper firmware. However, there are significant concerns raised regarding the sensor's functionality. A common issue reported is the difficulty in loading filament, where users mentioned that the filament tends to get stuck within the sensor, leading to frustrating experiences. In some cases, users encountered incorrect false positives that halted their prints, indicating that the sensor may require better calibration or firmware support. The lack of robust customer support for troubleshooting coding issues also received criticism, with some users feeling they needed a deeper understanding of coding to resolve problems. Overall, while the BIGTREETECH SFS V2.0 offers promising features that can enhance the 3D printing experience, it appears to have a challenging learning curve and mechanical issues that can affect its usability. **
