Installing AxioCNC on Windows

Install AxioCNC using the Windows installer, then launch it from the Start menu.

Prerequisites​

  • Windows 10 or 11 (x64)
  • USB connection to your CNC controller

Steps​

  1. Download the installer

    From GitHub Releases or axiocnc.com, download the Windows installer (e.g. axiocnc Setup x.x.x.exe).

  2. Run the installer

    Double‑click the downloaded .exe and follow the wizard. You can accept the default install location.

  3. Launch AxioCNC

    Open Start → AxioCNC (or search for “AxioCNC”). A browser window opens at http://localhost:8000.

Finding Your COM Port​

Before connecting to your machine:

  1. Connect the controller via USB and ensure it’s powered on.
  2. Open Device Manager → Ports (COM & LPT).
  3. Note the COM port (e.g. COM3, COM4).
  4. In AxioCNC, go to Settings → Connection, choose that port, set baud rate (often 115200 for Grbl), and select your controller type.

Troubleshooting​

COM port not listed

  • Reconnect the USB cable and check that the controller is on.
  • Install any driver your board vendor provides (e.g. USB‑serial).
  • Restart AxioCNC after connecting the controller.

“Port already in use” or connection fails

  • Close other apps that might use the same COM port (other CNC software, serial terminals).
  • Disconnect and reconnect the USB cable, then try again.

Uninstall

Use Settings → Apps → AxioCNC → Uninstall. See Uninstall for removing config data.
