S5 filament sensor does not detect end of filamant

Posted · S5 filament sensor does not detect end of filamant

I have a issue with the filamant sensors.

they seem to work if the filamant jams, or is held on the end of the spool,  but if the filamant is not held on the spool and flows through, it does not detect it- will happily keep  printing air and stuffing the print.

 

theres very little detail in how these detect and work, which makes it hard to work through fault finding.

 

any ideas on how to fix this?

    The filament sensor is built into the printers feeders, basically you will see a little PCB and thats got a wheel on it, thats the sensor and the filament moving should turn the wheel. when the filament runs out it should be pulled past the wheel and stop in the knurled wheel before it goes past it.

     

    So i don't see how it would work if you hold the filament from moving but then not work when it runs out past the sensor wheel.

    I ran into similar issue when we comissioned the printer. 

    A good cleaning of the extruder was the only thing we did and it's working as expected now. Oddly, the extruder was perfectly clean so I can't tell you why it worked...

    as an update- it appear that  the firmware works by using the movement rates relative to the stepper motor at the beginning as a reference.  So if there is no flow detected at the beginning, it will still continue to run.  I think this is waht was happenign in my case.

    A little official  description on how things work, even just a few paragraphs would help a lot with fault finding- its a shame the information on how these parts work is so scarce.

        (Sorry, was out of office when this released)

        This update is for...
        All UltiMaker S series  
        New features
         
        Temperature status. During print preparation, the temperatures of the print cores and build plate will be shown on the display. This gives a better indication of the progress and remaining wait time. Save log files in paused state. It is now possible to save the printer's log files to USB if the currently active print job is paused. Previously, the Dump logs to USB option was only enabled if the printer was in idle state. Confirm print removal via Digital Factory. If the printer is connected to the Digital Factory, it is now possible to confirm the removal of a previous print job via the Digital Factory interface. This is useful in situations where the build plate is clear, but the operator forgot to select Confirm removal on the printer’s display. Visit this page for more information about this feature.
