xTool S1 with 10W, 20W and 40W laser modules.

Issue description

You should see a pop-up error message that says "Light interference detected".

Ensure proper ambient light

The xTool S1 uses spectral and temperature sensors to determine if a flame is occurring. If the machine is used in direct sunlight, the spectral detection sensor may be disturbed, resulting in false alarms. Therefore, please try to place the machine in an environment with stable light and without direct strong light.For example, avoid placing the machine in front of a window, balcony, or other areas exposed to direct sunlight.

Location of the sensors

• There are two spectral sensors on each of the light strips.
• There are one spectral and temperature 2-in-1 sensor on the laser module.
