xTool F2 Ultra UV Auto Focus Issue
Updated Dec 24,2025
Updated Dec 24,2025

Issue description

A pop-up message indicating that the auto-focus failed appears at the top of the screen, or the measured thickness of the material to be processed deviates by more than 0.5 mm from the actual one.

Troubleshooting

During the automatic distance measurement process, if you adjust the laser module using physical buttons (manual focus) or click the reset function in the device settings, the automatic measurement process will stop. Therefore, please do not press any buttons on the controller during automatic distance measurement.

Step 1: Perform second calibration

Refer to this guide to perform a second calibration.

Step 2: Place the material correctly

The automatic distance measurement requires placing the material on the blue focus point. If the material is not placed correctly, automatic focusing may fail or may be inaccurate.

Step 3: Use compatible materials

This function is not suitable for transparent, semi-transparent, reflective, fluffy (cotton), or light-absorbing (black acrylic) materials. Please make sure the material is compatible.

Tip: You can place or wrap a thin, easily visible material over the surface to help with automatic distance measurement.

Step 4: Secure the connection

The device needs to take photos and send them to xTool Studio for image processing. If the device is disconnected or the Wi-Fi network is slow, the image transmission may fail, leading to automatic focusing failure.
