Replacing the Motor on Ray5 Mini/MiniS

The X-axis and Y-axis motors are essential components that drive precise movement during engraving. If the motor becomes faulty, you may experience issues such as inaccurate positioning, skipped steps, or complete axis failure.

This guide explains how to safely replace the motor on the Ray5 mini and miniS series. The overall procedure is similar for both X-axis and Y-axis motors, with slight structural differences between models.

1. Disconnect Components

• Disconnect the X/Y-axis motor cables
• Disconnect the laser module cable

2. Remove the Laser Module

• Loosen the M3×14 screws or L-shaped hand-tight screws
• Remove the laser module
