Tension Controlled Filament Winder Kit — Master Real-Time Motor Feedback with Arduino Uno

Every part needed, pre-tested for compatibility, with an AI build companion trained on this exact project. Shipped from Bengaluru in 3-5 days.

Picture a spooling machine that never snaps delicate filament — that's exactly what you'll build. A precision load cell continuously reads tension, and the Arduino Uno instantly adjusts the NEMA 17 stepper motor speed to hold your chosen setpoint. Whether you are respooling 3D printer PLA, winding coils for a science project, or demonstrating a sensor-driven feedback system, this kit turns control theory into a working device on your desk.

What You'll Build

You'll assemble a compact winding station where a 1 kg load cell senses filament pull in real time. The OLED screen shows live tension and target values. As tension deviates, the motor accelerates or slows to maintain a smooth, constant wind — no slack, no breakage. The result is a fully functional, programmable tension controller that you can customize or integrate into larger automation setups.

What You'll Learn

• Integrate a load cell with HX711 amplifier and calibrate it for accurate gram-level readings
• Implement closed-loop motor speed control using Arduino logic (proportional, derivative, integral)
• Drive a NEMA 17 stepper via A4988 driver and synchronize motion with sensor feedback
• Design and debug a physical mechatronics system — from breadboard wiring to final winding test
