Precautions before operation and machine status
Please take all necessary precautions when performing these operations, wearing insulated gloves is recommended. For some operations, please turn off the machine and wait for the print head to cool down completely
Operation steps
1-Remove the print head front cover
- Before the operation, you need to pull out the filament first, then power off the printer, and use a 2.0mm hex wrench to loosen the two fixing screws of the whole print head assembly.
- Separate the front cover of the whole print head assembly, and unplug the cable port of the "proximity switch" in the "extrusion adapter board".
- Use a Phillips screwdriver to loosen the four fixing screws of the "fan bracket" (two on each side), remove the "fan bracket" assembly, and place it on the top of the print head assembly (It will be easier to place it after combing the cables).
2-Replace the nozzle
- Remove the black "silicone sleeve" wrapped around the heated chamber (Make sure the nozzle has completely cooled down).
- Power on the printer, click [Prepare - Temperature] on the touch screen, and then set the nozzle temperature to 200°C in the temperature control interface.
- Use pliers to hold the square metal heated chamber, then use a 6mm socket wrench or a 6mm open-end wrench to loosen the nozzle and take it out (operate with the nozzle heated), and replace it with a new nozzle.
- Power off the printer, wait for the nozzle to cool completely, and install the black "silicone sleeve" wrapped around the heated chamber_x000F_
3-Install the fan bracket
- Place the "fan bracket" assembly into the mounting position (align the screw holes on both sides for easier installation), and use a Phillips screwdriver to tighten the four fixing screws of the "fan bracket".
- Use tweezers to hold the connecting cable of the "proximity switch" and insert it into the port of the "extrusion adapter board".
- Install the front cover of the whole print head assembly (It has a groove design and can be installed by sliding it in), and use a 2.0mm hex wrench to tighten the two fixing screws of the "print head front cover".
- Operate on the touch screen to re-level, and it can be used normally.
