After working with oily materials, such as pine boards, cleaning the lens in time is necessary. Cleaning method: use a cotton swab dipped in alcohol to wipe the lens. Please use a smoke exhaust device and ensure that the room or area you are operating the laser is well-ventilated Performance Electrical interface: XH2.54-3 Pin terminal (three-core cable, a: PWM +, b: GND, c: 12VDC) Laser shield: A movable laser shield that effectively shields the laser beam without affecting its working position.

SainSmart shows limited transparency regarding their sustainability practices and manufacturing processes. While they produce electronic products that can enable DIY repairs and reduce waste, their corporate responsibility reporting is minimal. There's little information about their supply chain ethics, labor conditions, or environmental initiatives. The company lacks clear policies on recycling programs and electronic waste management. Their packaging and shipping practices could be more environmentally conscious.
