What does filament sensor do?
The optical filament sensor detects the presence of a filament and also its movement. Make sure you are running the latest firmware since new versions offer a higher-frequency sensing algorithm and improved reliability.
How do I turn off my Prusa filament sensor?
In general, the Filament sensor is not vital for the printer, meaning you can always turn it off in the LCD Menu -> Settings -> Fil. sensor (toggle between ON and OFF) and continue using the printer.
What should I know about IR filament sensor troubleshooting?
IR Filament Sensor Troubleshooting (MK2.5S, MK3S) The IR sensor is a hybrid solution that combines an IR laser sensor triggered by a tiny mechanical lever. This means that in case one of the functions of the IR sensor is not working, the source of the issue might not be the sensor itself. In case you are experiencing:
What’s the difference between IR filament sensor MK3 and MK2.5?
The cables for MK3/S/+ and MK2.5/S IR filament sensors are different as they have different mainboards. On MK2.5/S the white wire is shifted one pin to the right. The picture below depicts the MK3/S/+ cable, but the position and orientation of the connector remain the same between the two models.
What is the status of the IR sensor?
Here you can see the status of all 3 sensors we are using on our printers: the PINDA, the FINDA and the IR sensor (which is one of the designations of the new filament sensor). See how the IR sensor status changes from 0 to 1 as you are inserting a piece of filament inside the opened extruder.
What happens when you run out of filament on a printer?
If you run out of filament, the printer will automatically pause the print, unload the remaining few centimeters of the material from the heatbreak, and move the X-carriage away from the print. You will be prompted to replace the spool and insert a new filament.
