Regular maintenance
Laser cutting will produce a large amount of dust and debris, which gradually accumulate on various parts inside the printer. Without regular maintenance, this can severely affect printing and laser cutting performance and may even prevent the device from working properly. This page introduces the components of the printer and laser module that require regular maintenance, along with related precautions, to extend device lifespan and ensure optimal performance.
- Cameras and markers for visual recognition:
The following parts are easily tainted by dirt that could result in recognition errors. Regularly use alcohol and a non-woven cloth to clean them, including the lenses of the nozzle camera, tool head camera, live view camera, and birdseye camera, markers on the quick-release lever; hotends, build plate and laser platform, and stoppers on top of the heatbed. - Inner walls and surfaces of metal and plastic parts:
Dirt tends to accumulate on the inner walls of the printer. If left uncleaned for prolonged periods, it can obstruct visibility from the front door and safety windows. Regularly use alcohol and a non-woven cloth to clean these parts. You also need to clean parts such as the part cooling fan air duct, flow blocker and its magnetic bracket on the toolhead, X-axis linear guides, and the rods and lead screws of the Y and Z axes. Please note that after cleaning metal bearing with alcohol, promptly apply lubricating oil (for linear guides and rods) or grease (for lead screws). - Air filter cover, automatic top vent, chamber exhaust fan, and active chamber exhaust:
These components are primary mediums for air exchange between the inside of the printer and the outside and are prone to dust accumulation. Regularly use a brush to remove the dust. For the air filter cover and active chamber exhaust, you can disassemble them for thorough cleaning. - Laser module surface, heat sink on top, and internal fan:
Regularly use alcohol and a non-woven cloth to clean the flame sensor and laser lens, and use a brush to remove the soot from the heat sink and fan. Detergent is recommended for severe contamination.
