What happened?
The printer is equipped with a filament sensor that can detect filament presence. In case the filament is not detected when the printer expects it to be loaded, the printer shows the message "Filament not detected. Load filament now? Select NO to cancel the print. Select DISABLE FS to disable the filament sensor and continue print"
Error name: Filament not detected
Error code: #31804 (CORE One) #26804 (MK4S) #27804 (MK3.9S) #28804 (MK3.5S) #13804 (MK4) #21804 (MK3.9) #23804 (MK3.5) #17804 (XL) #12804 (MINI)
How to fix it?
The possible actions depend on the specific scenario.
If the filament is not inserted in the hotend, load it using the Load filament function from the printer menu.
In case the print encountered a problem or skipped parts as a result of the filament not being detected, select NO to cancel the print.
In case the print can be continued without issues, but the sensor doesn't detect the filament being inserted, consider selecting DISABLE FS.
In this scenario, after the print and with the printer fully cooled down and off, check our troubleshooting articles, depending on your printer model, for the filament sensor. Do not hesitate to contact our Customer Support at any time.
