Prusa i3 MK3S Filament Sensor rev. and FW In the latest firmware release (at the time of writing this article) Prusa Research added a feature for filament sensor recognition (available for i3 MK3S only). Essentially the printer can tell when then filament sensor is disconnected and can interrupt the print and wait for user action.
19/02/2020· It is under the top cover, remove the screw holding the cover down and remove the cover. You will then see a smaller screw holding the IR sensor down. My IR sensor is very sensitive to the tightness of this screw. If I tighten it a quarter turn, my sensor will always read 1. When my printer is printing without filament, I loosen this screw.
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. Issues can appear as: Autoload not …

Filament IR Sensor Unknown State Prusa I3 MK3S. I have been trying to figure out a problem I have had since I got my printer put together on 6/15/2020. It was something I didn''t notice right away until a friend with the same printer told me my autoloading wasn''t working. Unlike others on the Prusa forums, I am not experiencing the issue that seems to be the filament showing a 0 or 1 but rather ...
Get or set filament runout status and distance. Omit all parameters to get a report of the current stats. Enable or disable filament runout detection with S and set distance with D. When filament sensors are enabled, Marlin will respond to a filament runout by running the configured Gcode (usually M600 Filament Change). When filament runout detection is disabled, Marlin will take no action ...
The Ender 3 does not come with a filament runout sensor built in, unlike some higher end printers such as the Prusa MK3. Many of the 32bit boards available for use on an Ender 3 have open connectors for filament runout sensors so if you have already swapped your board then you have this as an option. Installing the smart filament sensor on your Ender 3 is not difficult but will require some ...
Wondering if anyone has had a similar problem with the IR sensor. I have the MK3S+, kit version, built it early August 2021. IR sensor has worked from day 1. A couple of weeks ago I noticed the sensor stopped working. Took everything apart per Prusa support site, fired it up and the sensor works again. I load the filament and after that it goes ...

20/12/2019· RE: Filament Sensor (IR) problem. her is my fix. The sensor works fine unless i tighten the case. It take me some time to figure out, whathe the issues was. If the Case is open, the Sensor works fine. After i close the case, the sensor doesnt work anymore. All things are moving but i got continourly a 1 from the senor.
the IRsensor on the top of the Extruderbody and secure it with the M2x8. the M2x8 screw, the sensor shouldn''t be able to move, but be careful the PCB isn''t indestructible ;) the cable, mind the correct orientation of the connector and wires. a slack behind the sensor like in the picture. Don''t create too big loop as it might interfere with the frame. If ...
06/08/2019· FIlament Sensor n/a. I''m using the mk3 with the latest firmware ( b138) and filament sensor does not work. When I started with the machine the sensor saved 4 prints, so I know it was working at one point. Then I turned the sensor off and it wouldn''t let me turn it back on. I assumed this was the firmware, so I waited until the newer ...
