Product Name: IR Sensor
(I3 MK3 TO MK3S UPGRADE NEW FILAMENT SENSOR)
Upgrade Filament Sensor:
The new sensor is using an optical sensor which is triggered by a simple mechanical lever.
This sensor doesn’t care about the optical properties of the filament (it can be completely
invisible) and cannot die because of mechanical wear.
IR Sensor Assembly:
1. Place the IR-sensor on the top of the Extruder-body and secure it with the M2x8.
2. Tighten the M2x8 screw, the sensor shouldn’t be able to move, but be careful the PCB
isn’t indestructible 😉
3. Connect the cable, mind the correct orientation of the connector and wires.
4. Leave a slack behind the sensor like in the picture. Don’t create a too big a loop as it might
interfere with the frame. If needed adjust the length by gently pulling/pushing the cable.
Function:
1. The optical filament encoder detects the presence of a filament and its movement.
2. The MK3 can recognize, that filament is running out, pause the print and ask the user to insert a new spool.
3. It can also detect stuck filament and offer the user an option to clean the nozzle.
Note:
Don not touch the black PCB nor the chips on it.
