====== Maintenance ====== 3D printing is still a technology that relies heavily on trial and error. It's nearly impossible to master the technology without getting your hands dirty. As there are no globally recognized standards in the 3D printer, material, or software manufacturing, it is vulnerable to a variety of printing problems. A multitude of 3D printer issues results in failed prints, which leads to a loss of business, if not your interest in the technology. \\ To make sure you don’t feel bogged down by the problems and abandon this revolutionary technology, we list down the most popular 3D printer problems and ways to troubleshoot them. {{ :tina2:图片1.png?nolink&600 }}{{ :tina2:图片2.png?nolink&600 }}\\ ====== How to maintain it if not used for a long time ====== ===== ① Filament ===== After printing is completed, please exit the remaining filaments from the printer and seal them for storage. {{ :tina2:图片3.png?nolink&800 }} ===== ② Lead screw ===== When the printer is in use, the X and Y directions rely on precision guide rails and Z-axis screw rods to ensure smooth and precise linear motion. After adding lubrication silicone grease, it can reduce friction and reduce the wear of mechanical moving parts, so it must be maintained regularly. It is recommended that maintenance be performed after 1,000 hours of use. Take out the lubricating silicone grease from the random accessory box and apply it evenly on the screw rod.\\ {{ :tina2:图片4.png?nolink&400 }} ===== ③ Power supply ===== If not used for a long time, please turn off the power. Keep the place of use clean and dry. Prevent dust accumulation at the power input and output ports. The power supply should be protected from rainwater and direct sunlight. Put on the bag.\\ {{ :tina2:图片5.png?nolink&800 }}\\ ====== Clogged ====== If the filament does not come out, or the extruder makes a "click" sound, or the model prints poorly, it is blocked. During the 3D printing process, some debris and dust particles in the filaments may accumulate around the printing nozzle. Over time, these build-ups can lead to poor printing accuracy or clogged nozzles.\\ {{ :tina2:图片6.png?nolink&800 }}\\ ===== ① Fan ===== Please check if the fan is working properly while printing. If the fan does not rotate, it will cause the nozzle to become clogged.\\ {{ :tina2:图片7.png?nolink&400 }}\\ If the fan fails, replace the fan:\\ 1. Use a 2.5mmL wrench to loosen the 4 screws.\\ {{ :tina2:图片8.png?nolink&800 }}\\ 2. Cut off the ties and untie the black wrapping cloth.\\ {{ :tina2:图片9.png?nolink&800 }}\\ 3. Unplug the fan, untie the tape, and remove the fan. {{ :tina2:图片10.png?nolink&800 }}\\ 4. Replace and install a new fan, making sure the fan label is facing inward.\\ {{ :tina2:图片11.png?nolink&800 }} ===== ② Filament ===== The printing temperature of the filament is low, the quality is poor, the filament becomes brittle due to moisture, or is dusty, or becomes entangled during printing, which will lead to clogging.\\ {{ :tina2:图片12.png?nolink&800 }}\\ If the filament is wet, brittle, or dusty, please do not use it. If the filament is tangled, please sort it out.\\ If the filament printing temperature is too low, please increase the temperature by 15°C. You can also print the following model to determine the optimal temperature of the filament.\\ {{ :tina2:图片13.png?nolink&400 }} ===== ③ The filament is stuck in the extruder or tube ===== {{ :tina2:图片14.png?nolink&800 }}\\ The filament is stuck in the extruder or tube: 1. Cut the filament into a bevel and insert it into the extruder. {{ :tina2:图片15.png?nolink&800 }}\\ 2. If there are impurities inside the tube, cut off this section of the tube.\\ {{ :tina2:图片16.png?nolink&400 }} ===== ④ Irregular operation may lead to clogging. Please clean the nozzle ===== When replacing the filament, if you pull it out directly, the filament will also stick to the nozzle and tube, causing blockage. Therefore, when we replace the filament, we need to use the "Unload the filament" function.\\ {{ :tina2:图片17.png?nolink&800 }}\\ If it is clogged, please operate accordingly and clean the nozzle:\\ 1. "Unload the filament".\\ {{ :tina2:图片18.png?nolink&400 }}\\ 2. Press the tube fitting and remove the tube.\\ {{ :tina2:图片19.png?nolink&400 }}\\ 3.
