	(c)Check the pneumatic fittings. A loose coupling could therefore allow molten filament to leak into a gap between the tube and the nozzle. This will restrict the flow of the filament, causing the extruder keep clicking.		(c)Check the pneumatic fittings.

	(d)Change the extruder gear. After many hours of use, the teeth of the extruder may eventually wear out. Thus, it can no longer hold the filament, leading to filament slipping in the extruder.

	~~(c)The first layer is messy~~

	Please clean the hotbed before printing, this will help to get a good adhesion. We recommend a thicker first layer, 0.3 mm is good. If these’re not helpful, please try to adjust the Z-offset. What’s more, you can try adjust the hotbed temperature, for example, the Geeetech wood PLA needs a lower hotbed temperature but PETG needs higher.

			The spring steel sheet is flexible and easy for part removal. But keep in mind that prints are easy to remove after the plate cools down. Don’t try to forcefully remove the object when the sheet is still hot. We do not suggest you use the adhesive on the sheet, because the adhesive is difficult to clean up and may have an opposite effect.

			If there’re leftover residue on the sheet, preheat the hotbed to 80 degrees to make the plastic soft. Then use the wet cloth wiping the plate and gently scrap the residue off.

			A dirty bed will cause poor first layer adhesion. You need to remove the dirt, leftover residue or oil from the bed surface. Isopropyl alcohol (IPA) 90%+ will help to degrease the platform.

			Download the latest firmware in our website:

			How to update:

			1.Put "bin” file and "assets” folder in TF card root directory, insert TF card into the printer.

			2.Turn on the printer, the screen will display the firmware upgrade progress bar.

			3.After the progress is complete, the printer starts to upgrade UI.

			4.Update is complete.

			'''Notice:'''

			'''1.After the upgrade, delete the bin file and assets folder in the TF card to prevent repeated upgrades.'''

			If there’s error on the screen prompts like “Change Filament” even filament has been uploaded, maybe the sensor is broken. You can test it by a multimeter.

			Remember load a small piece of filament through the sensor before test. By touching each of the measurement leads of the multimeter to the two pins of the sensor, a signal (beep or 0 value on the multimeter screen) will indicate that the component is intact and therefore, should work.
