①To confirm filaments are in a dry state (If unpacking time is too long, filaments need to dry again; PLA, 50-55, 3h; PETG, WOOD & ABS, 60-65, 4h; TPU, 65-70℃, 4h).

②To lower the printing temperature.

③To increase pumping back distance and speed.

①To confirm filaments are in a dry state (If unpacking time is too long, filaments need to dry again; PLA, 50-55, 3h; PETG, WOOD & ABS, 60-65, 4h; TPU, 65-70℃, 4h).

②To increase or reduce extrusion amount appropriately.

③To clean up the throat and the nozzle.

④ To check whether extruder gears wear or not.

①To adjust the distance between the nozzle and the platform.

②To reduce the first layer’s printing speed.

③To adjust the temperature and cooling settings.

④Platform surface treatment (platform stickers, glue, and materials).

⑤To add brim or draft.

① The cause may be the too-high layer height. You should reduce the printing height of every layer.

② The cause may be the too-low printing temperature. You should increase the printing temperature appropriately.

③ The cause may also be the too-low ambient temperature. You should properly insulate the printer cavity.

①To reinstall the wire, and check whether the new wire can be extruded or not.

②To clean the nozzle with a needle, whose diameter is slightly smaller than the nozzle, or to replace a new nozzle.

③To confirm whether the throat cooling fan is in normal operation. If not, it will lead to filaments melting and expanding in the throat, resulting in blockage.

④ To check whether the throat ages.

①To check the reminder of filament.

②The cause may be the slippage of wire and drive gear. You should check if the drive gear wears or adjust the printing speed.

③The cause may be the clogged extruder. Pls refer to solutions to Q5.

④The cause may also be the overheating extrusion electrical driver. You should add additional cooling to the driver.

① You should tuck the wire in the round hole on the side of the material tray and snap it tight when you disassemble the material every time.

② If the wire has been strung, you should pull out the wire until it is not strung, then rewrap it.

You should dry it in the oven for the time span of 1-2 times. Thus, the internal stress of the wire can be eliminated, and breakage improved.

① The cause may be insufficient heat dissipation. You should increase the printing cooling, or adjust room temperatures with an electric fan or air conditioner.

② The cause may be too-high printing temperature. You should reduce the printing temperature by 5-10 appropriately. If there is no improvement, pls repeat it.

③ The cause may also be too-fast printing speed, resulting in models having no enough cooling time for printed products. You can reduce the printing temperature, or print more than one model at a time.
