After replacing the nozzle, please recalibrate the distance between the nozzle and the build plate to ensure the quality of printed parts. How to replace nozzles? 1: Turn on the 3D printer, heat the nozzle and heating block to the target temperature (PLA: 180-220℃, ABS: 240-280℃). 2: After heating, turn off the printer, use a wrench to hold the heating block. Then use a socket wrench to unscrew the old nozzle. Note: Please do not touch the old nozzle and heating block to avoid burns. 3: Keep the heating block held with the wrench, use the socket wrench to screw in the new nozzle, ensuring it is firmly seated.
