RFID filament detection failing


Recommended Posts

Posted · RFID filament detection failing



I am struggling to change filaments spool with the material station.

At least the printer is struggling to recognize which filament I am inserting.

(I am using Ultimaker filaments spool)

(printer model S5 - September 2020 batch)


Steps I take :

  1. open the material bay door
  2. press + sign on the chosen feeder (A,B, etc...)
  3. press "load" button 
  4. insert the spool with the sticker on the left (filament going down)
  5. guide the filament tip into the chosen extruder.
  6. the screen show a yellow exclamation mark ==> the filament spool is not recognized...
  7. I unload pressing the up arrow button.
  8. Start again from number 2. 


I tried several times on different feeders... Without any luck.

I tried to select the filament manually, but I can't find the right one in the menu.

Here, I am looking for Ultimaker PLA Black

All I find is just PLA without the possibility to choose the color etc... 


How to change filament spools ?

What to do for the Material Station to detect the spool ?

How to select the right filament spool in the menu when everything else fail ?

    I can give you just a generic hint, I have no material station, but it is basically ok that you cannot select UM PLA manually. But you have to know that when you select PLA manually then you have to select Generic PLA in Cura and not the UM PLA even if you loaded a UM spool. In fact it doesn't matter the profiles are the same, but you have to know that. Not a nice solution but a workaround if it is just with one UM spool.


    And regarding auto detect of the NFC tag, have you tried another spool? I am asking because I also have one UM spool (also PLA back) which is not recognized by the printer. I guess there a problem with this nfc chip on the spool or maybe the batch of the spools have some problems. All other UM spools are working fine for me.

    Could be, I don't know, but just try it when you have finished your print job.

    If the printer also cannot detect other spools then it must be something else.

    Great, thanks for the feedback.

    I guess there is faulty batch of UM PLA black, it is my only spool which could not be detected.

      • S-Line Firmware 8.3.0 was released Nov. 20th on the "Latest" firmware branch.
        (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.

      • Ultimaker Cura 5.6 stable released
        Cura now supports Method series printers!
        A year after the merger of Ultimaker and MakerBotQQ, we have unlocked the ability for users of our Method series printers to slice files using UltiMaker Cura. As of this release, users can find profiles for our Method and Method XL printers, as well as material profiles for ABS-R, ABS-CF, and RapidRinse. Meaning it’s now possible to use either Cura or the existing cloud-slicing software CloudPrint when printing with these printers or materials
