Yes, it is safe to use the machine. The xTool M1 prioritizes safety with its enclosed working area, light filtering lid, built-in fan with ventilation hose, and preassembled setup. The safety enclosure covers the entire working area, while the light filtering lid allows for safe project viewing. Opening the lid during operation automatically stops the machine. The built-in fan and ventilation hose effectively remove smoke and dust. With the xTool M1, safety is ensured from setup to operation.
