After restarting Mach3, move each axis manually using the on‑screen JOG buttons or the keyboard arrow keys. If the motor direction is reversed, you can either swap the A+/A– and B+/B– wires on the driver side, or change the “Dir LowActive” setting in Mach3’s motor tuning menu.
While does not offer a direct driver download, it hosts a comprehensive PDF manual that includes the complete Mach3 configuration steps, the plugin‑selection procedure, and the kernel speed settings (25 kHz, 45 kHz, 65 kHz, or 100 kHz). The manual is essential reading before attempting to install the driver. Open the Plugins folder inside the Mach3 directory
