3：Remove the print head front cover after the nozzle is completely cooled。
|
4：Remove the warm cover and the hot end fixing screws, and remove the hot end
|
5：Remove nozzle using wrench and socket
|
6：After replacing the new nozzle and fixing the hot end, fix the front cover of the print head
|
7：Re-insert consumables to start feeding
|
Safety precautions：
When replacing the nozzle, pay special attention to the temperature of the nozzle may still be very high during the discharge and heating process, and be careful to avoid burns。
¶ SK1 Replace the hot end
3D printer hot end component replacement process
1：Before replacing the hot end, be sure to return the consumables to ensure that there is no residual material in the extruder
|
|
2：Use the tool to unscrew the drag link, then carefully remove the back cover and front cover of the printer

¶ SK1 Adjust belt tightness
3D printer belt tension adjustment method
1：Locate the adjusting screw on the printer belt tensioner and loosen the screw under the tensioner so that you can freely adjust the tightness of the belt and manually adjust the belt until the appropriate tension is reached。
|
2：After confirming that the belt tension meets the requirements, re-tighten the screw of the tensioner to fix the belt tension
|
Matters needing attention：
- During the adjustment process, please ensure that the belt is not too tight or too loose, so as not to affect the normal operation of the printer。
- When adjusting belt tension, be careful to avoid damaging the belt or other parts of the printer。
