Filament Tension Controller Kit with Arduino Uno & Stepper Motor
Filament Tension Controller Kit with Arduino Uno - Precision Winding for 3D Printing Spools
Every part needed, pre-tested for compatibility, with an AI build companion trained on this exact project. Shipped from Bengaluru in 3-5 days.
Say goodbye to tangled filament spools and uneven winding. This kit lets you build a real-time tension monitoring system that actively reads filament pull using a 1kg load cell and instantly adjusts a NEMA 17 stepper motor's speed to keep tension perfectly constant. Originally designed for 3D printing filament spoolers, it's also ideal for wire winding, thread coiling, and any application where consistent tension matters.
What You'll Build
You'll assemble a compact, breadboard-based controller that continuously senses filament tension via the HX711 amplifier, displays real-time values on a 0.96-inch OLED, and drives the stepper motor through an A4988 driver. The result: a closed-loop system that prevents slack and snap-back, delivering uniformly wound spools every time.
What You'll Learn
- Implement PID logic to maintain a target tension setpoint
- Interface a load cell with the HX711 24-bit ADC and calibrate for accurate force readings
- Drive a NEMA 17 stepper motor precisely with an A4988 microstepping driver
- Display live sensor feedback on an I2C OLED, mapping tension to motor speed

Who This Kit Is For
Designed for CBSE Class 11-12 students exploring sensor-actuator integration, B.Tech ECE/EEE undergraduates building automation projects, Smart India Hackathon teams working on filament recyclers, ATL tinkering labs needing a ready-to-run motion control demonstration, and makers at IIT/NIT/VIT/BITS who want to add precision winding to their 3D printing setup.
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 inside the box to access the AI companion, which walks you through wiring, calibration, and code troubleshooting step by step. WhatsApp support is also available for extra help.
Can I use this to wind wires or threads instead of filament?
Absolutely. You can set any target tension value in the code, making it adaptable for copper wire, nylon thread, or similar materials - as long as the load cell's 1kg range is not exceeded.
Does the kit include the filament spool or winding mechanism?
No, the kit provides the electronic control system only. You'll need to mount the load cell and stepper to your own spooler frame or a simple 3D-printed winding jig.
Can I integrate it with an existing winding machine?
Yes, the load cell and stepper can be retrofitted onto most manual winders. The sensor output is accessible on the OLED, and you can modify the open-source code to sync with external triggers.
Health - Load cell measures filament tension. Stepper adjusts winding speed to maintain constant tension.
