If there are filaments blocked in the print head throat, please heat the nozzle temperature to 200 degrees, wear insulated gloves, and use pliers to grip the throat. Then take a section of filaments, slowly push the filaments into the print head throat, so that the blocked is extruded from the nozzle.
(1)Replace the new hotend, insert the hotend into the heat dissipation block, and keep the pipe step flush with the heat dissipation block.
Note: When removing the hot end of the print head and reinstalling it, you must check whether the print head is in place. (If it is not installed in place, the hot end nozzle may scrape the hot bed)
(2)Then push the handle down to clamp the pipe, and the handle exceeds the insulation sleeve, and then flip the hotend to check whether the hotend is fixed in place.
Note: If the ceramic tube is pulled out during the installation of the hotend, and it is difficult to put it back in the cooling state, please wear temperature insulation gloves, properly heat the nozzle temperature, and use tweezers to put the ceramic tube back.
(1)Please connect the hotend cable back to the printhead adapter board, and then connect the model cooling fan with the extension wire, and arrange the wire.
Note: Do not insert the hot end cable in place as shown in the left picture. Please insert the hot end cable in place as shown in the right picture. (If the hot end cable is not installed in place, it may cause the hot end to fail to heat.)
(2)Finally, fasten the print head case on the print head.
