Extruder Filament Sensor Hall Switch Board with Flexible Cable

as someone who's into 3d printing for fun and learning, i had this ongoing issue where my prints would just stop midway because the filament jammed or ran out without me noticing. it was so frustrating, wasting time and material. then i found this sensor from hard worky, and it's been a game-changer. installation was a breeze with that bendy cable—no tools needed, just connected it up. now, it alerts me if anything goes wrong, and my prints finish smoothly. the takeaway is that this is a must-have for anyone with a compatible printer; it gives peace of mind and makes the whole process way less stressful. i'd definitely recommend it to others in a similar spot! 😊
- Pros: i really appreciate how this little board keeps an eye on my filament, so i never have to worry about a print failing because it ran out or got stuck. the flexible cable made it super easy to install, just plugging it in without any hassle. it's incredibly reliable and has saved me from so many potential messes.
- Cons: it gets a bit warm after long prints, which makes me a bit nervous, and i wish it worked with more printers, not just the specific ones. sometimes i feel it could be a bit more sensitive, but i could be wrong about that.
