¶ Troubleshooting and solution
-
- Please try restarting your printer. Sometimes, a simple reboot can help resolve minor issues and restore normal functionality.
-
- Verify that your firmware is up to date. It is important to ensure that you are using the latest firmware version, as updates often include bug fixes and improvements. Please check the official Creality website for the most recent firmware release compatible with your printer model.
-
- Check the communication between the nozzle and the mainboard. Start by disconnecting and reconnecting the connection cable. Additionally, observe the blue indicator light on the nozzle's small board. It should remain illuminated constantly. If you have a multimeter available, you can set it to the buzzer mode and test for continuity between the terminals at both ends of the connection cable. If there is no continuity, it may be necessary to replace the connection cable. Once the cable issue has been ruled out, we may proceed with replacing either the nozzle's small board (2101020226) or the mainboard (4002020063).
