			[[File:M35.png]]

			Unload the filament from the hotend.

			[[File:M36.png]]

			Remove the Teflon tube from the hotend.

			[[File:M37.png]]

			Use a cleaner rod (1.5 mm diameter, 100 mm length) to push it in and out several times, making the clog out. Do not use excessive force.

			[[File:M38.png]]

			Use a needle to clean the nozzle.

			[[File:M39.png]]

			'''Step 2 Replace a nozzle'''

			Turn the printer off.

			Remove the print head housing.

			Release the old nozzle with a 6mm spanner while holding the heater block in place with a 20mm spanner.

			[[File:M40.png]]

			=== '''Mintemp error'''===

			The Mintemp error in 3D printers is a design feature within your firmware for safety in regard to temperature. When below a set temperature, the heater will be switched off due to possibly having a broken thermistor wire. It can be observed a negative the temperature on the LCD screen.

			[[File:W21.png]]

			Check if the hot end connector and thermistor are connected properly as the pictures below. Check the hotend cables and thermistor, make sure they’re not broken or burn out.

			[[File:W22.png]]

			You can test the thermistor by a multimeter. If it fails to read the resistance, then the wire is broken. At room temperature, it should be 80 kΩ - 125 kΩ.

			[[File:W23.png]]

			Or apply heat to the thermistor with a heater, blow-dryer or other heating device.

			The resistance should decline steadily in seconds if it works. If not, replace it.

			Another common reason behind getting the MINTEMP error is from being in a cold environment, especially in winter months. Your 3D printer is designed to have a minimum temperature that it can operate in as a safety feature.

			=== '''Filament sensor'''===

			The filament sensor will be worn out after long time use. We’ve uploaded a [https://www.geeetech.com/download.html?version_id=554 filament guide] on our website to fix this.

			[[File:W40.png]]

			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.

			[[File:W1.png]]

			=== '''Update Firmware'''===

			[https://www.geeetech.com/download.html?download_id=62 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.

			2.Level the hotbed after the upgrade is complete.'''

			=== '''Nothing is printing'''===

			(a)Nozzle is too close to the hotbed
			Even though the extruder is working but no filament is depositing on the hotbed, Check if the nozzle is too close to the hotbed. Adjust the Z-offset value slightly will help.

			(b)Print temperature is too low
			Some filament needs more higher temperature, manually feed the filament, if it can not be extruded, please try increase the print temperature.

			(c)The extruder is not working
			Check if the grub screw on the extruder gear. If the grub screw is loose, the gear will fail to grab the filament when feeding into the hotend. Also check if the extruder motor is connected properly.

			=== '''Automatic leveling failed'''===

			(a)Nozzle calibration failed
			You should use a scraper against the nozzle and gently push up to make the nozzle “feel” the pressure. If this still fails, check if the strain gauge in the hotend is connected properly, and ensure the cables are not broken.

			[[File:W29.png]]

			(b)Homing failed
			Check the X, Y and Z axes end stops, make sure they’re all connected properly. Note the photoelectric end stops on the Y and Z axes, which normally have a blue signal light.

			[[File:W30.png]]

			(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 temperature but PETG needs higher.

			=== '''The printer is unstable'''===

			Make sure you put the printer on a stable platform, then check if the gantry kit is tightened. Make sure the four rubber mats are all tightened.

			[[File:W31.png]]


			=== '''Spring steel sheet problem'''===

			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.

			=== '''The extruder keeps making a noise'''===

			(a)Decrease the print speed. If the print speed is too fast, the extruder will push the filament too quickly. Filament may not have enough time to melt and even clog in the nozzle. A clogged nozzle will then exert pressure back on the extruder, resulting in clicking. For PLA, our recommended print speed is 60mm/s.

			(b)Increase the print temperature. If the temperature is too low, it will not melt the filament properly. This can also clog the nozzle. As the extruder is no longer able to push the filament ahead, it starts “slipping”.

			(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.

			[[File:W24.png]]

			(d)A low-tension extruder arm bar. If spring tension is too low, the extruder gear will not properly grip the filament. This leads to filament grinding.

			[[File:W25.png]]

			(e)Check if the grub screw on the extruder gear. If the grub screw is loose, the gears will fail to grab the filament when feeding into the hotend.

			[[File:W26.png]]

			=== '''Turn the printer on but the screen does not work'''===

			'''Warning:
			Never install or unplug anything on a printer while it’s being powered!'''

			(a)Please check if the power supply is working normally. The red indicator on the switch should be light. Please measure the output voltage, which should be around 24 Volts.

			[[File:W15.png]]

			(b)Check the fuse in the little black box, it should be complete without burns. Also check if the power supply connector is burn out or connected tightly.

			[[File:W16.png]]

			(c)Please check if the control board is working normally. There’re one green LED and one red LED working as the picture shown below. Measure the input voltage of the control board, it should be around 24 Volts.

			[[File:W20.png]]

			(d)Make sure the screen is connected properly.
