Open Device Manager. Under “Ports (COM & LPT),” you should see “XH190 Serial Device (COMx).” Open a terminal emulator (e.g., PuTTY) at 115200 baud, 8N1. Sending +++ should return an OK if the firmware is responsive.

Smooth motion is essential for high-quality surface finishes on CNC machines. The XH190 offers selectable microstepping resolutions, typically ranging from 400 to 25,600 steps per revolution. Higher microstepping results in smoother motor movement and reduced resonance, eliminating the "cogging" feel often associated with full-step driving.

After reboot, open Device Manager and expand Ports (COM & LPT). You should see something like USB-SERIAL CH340 (COM3). This confirms that your XH190 driver is active.
