¶ 1. Phenomenon Description
¶ 2. Cause Analysis
- Issue with filament break detection module
- Damaged filament break detection cable
- Mainboard malfunction
¶ 3. Troubleshooting and Solutions
- First, check if the filament break detection light turns on when filament is inserted. (Note: without filament, the blue light is dim; when filament is detected, it becomes bright)
- If you have a multimeter, check if the filament break detection cable has any short circuit or open circuit issues.
If the blue light doesn't show from the beginning, after troubleshooting cable issues, please directly measure the voltage at pins 2 and 3 of the mainboard port to see if there's 5V voltage. If not, please contact cs@creality.com to replace the mainboard.
If the power supply is normal, please measure the voltage between pins 1 and 2. When the filament break detection light is working normally and the cable is fine, the voltage should be around 2.5V without filament, and about 0.28V when filament is inserted. If the voltage is abnormal, please contact cs@creality.com to replace the mainboard. .
