Filament Tension Control Kit with Arduino Uno - Stepper Motor Winding
Arduino Uno Filament Tension Control Kit - Maintain Constant Spooling Tension
Every part needed, pre-tested for compatibility, with an AI build companion trained on this exact project. Shipped from Bengaluru in 3-5 days.
In filament extrusion or DIY spool winding, uneven tension causes breakage, diameter inconsistency, and wasted material. This kit lets you build a closed-loop tension controller: a 1 kg load cell senses filament pull, the Arduino Uno processes the signal, and a NEMA 17 stepper adjusts the feed or winding speed to maintain steady tension. Real-time data appears on a 0.96-inch OLED, giving you a fully functional tool for your 3D printing filament setup or small-scale logistics test rig.
What You'll Build
A practical tension-regulation module. The load cell and HX711 amplifier measure subtle force changes as filament passes through a guide, and the stepper motor immediately speeds up or slows down to compensate. The result is a consistent tension loop that protects fragile materials like 1.75 mm PLA or PETG during spooling, respooling, or even direct extrusion monitoring. The OLED displays current tension in grams and motor RPM, turning raw sensor data into actionable control.
What You'll Learn
- Interfacing an HX711 24-bit ADC to get precise load cell readings
- Driving a NEMA 17 stepper with an A4988 microstepping driver
- Implementing a proportional control algorithm for real-time speed adjustment
- Displaying live sensor data on a 128x64 OLED using I2C

Who This Kit Is For
B.Tech ECE and mechanical engineering students will find this a hands-on companion to motor control and sensor integration courses. It is ideal for Smart India Hackathon teams prototyping logistics automation, ATL Tinkering Labs exploring feedback systems, and CBSE Class 11-12 students building functional physics projects. Hobbyists winding filament spools or experimenting with constant-tension wire feeding will also get immediate, practical use.
Built and Backed by Compoden
Every Compoden kit ships with an AI build companion trained on this exact project - accessible via a QR code on the box, with WhatsApp and email backup. We've spent 10 years building projects for makers, schools, and institutions across India. If a part fails because of a manufacturing defect, replace it free within 7 days.
What if I get stuck during the build?
Scan the QR code on the box to chat with the AI companion, which knows every step of this specific project. You can also reach us on WhatsApp for quick help.
Can I use this kit to wind materials other than 3D printer filament?
Yes. As long as the material's tension falls within the 1 kg load cell range, you can calibrate it for thread, thin wire, or light rope by adjusting the guide fixture.
Do I need prior experience with stepper motors?
None. The AI guide introduces the A4988 driver, wiring, and code from scratch. Basic Arduino familiarity helps, but the build is structured for intermediate learners.
What is the maximum measurable tension?
The included 1 kg load cell reads up to approximately 9.8 N. For 1.75 mm filament, this covers typical spooling tensions with good headroom.
Logistics - Load cell measures filament tension. Stepper adjusts winding speed to maintain constant tension.
