NEMA 17 Stepper Motor Driver Development Kit

This model supports the development of stepper motor driver hardware and software by providing precise rotor angle measurement. Included is a snap-on rotor equipped with two goniometer scales, designed to fit standard NEMA 17 stepper motors.

Scale 1: Standard 1.8° step resolution with 200 ticks per full rotation (100 ticks at 3.6° intervals).

Scale 2: High-resolution scale with 180 ticks at 2° intervals.

The rotor is dynamically balanced to enable high-speed operation with minimal vibration.

A checkerboard calibration pattern is also included to fine-tune color alignment for optimal bicolor HueForge printing of the angle scales.

Bicolor (or Tricolor) Printing Instructions

The rotor and scales are designed for two-color or three-color printing. The provided .3mf file contains 2–3 separate objects.

Print orientation: Upside down, with all parts flat on the build plate.

Layer height: Use 0.08 mm for the first 3 layers for best visual results.

Nozzle size: A 0.4 mm nozzle works well; a 0.2 mm nozzle will produce even finer detail.

Material: Tested with PLA+ on a Creality K2 Plus.

Use the checkerboard pattern to test and optimize your color alignment before final printing.

Mounting

Four mounting you need 4 M3*8 mm Hex Socket Screws.
