NEMA17 Stepper Motor with Belt Drive (GT2 Timing Belt) – Simple Test Setup

In this short project, I set up a simple test with a NEMA17 stepper motor and a GT2 timing belt. The motor is controlled by a DRV8825 driver and an Arduino Nano ESP32 running MicroPython. I 3D-printed the motor mount, idler supports, and shaft collars, and used a small ball-bearing pulley to keep the belt tensioned. The code simply moves the motor back and forth to test the mechanics — nothing fancy, just a first experiment to see how smoothly it runs. Components used: – NEMA17 stepper motor (17HS4401) – GT2 timing belt (6 mm) and pulleys – DRV8825 driver module – Arduino Nano ESP32 – 100 µF capacitor, breadboard, 3D-printed mounts If you have any tips for improving belt tension or alignment, I’d love to hear your ideas in the comments. Thanks for watching!
