UMS5 Pro Bundle - Print not starting


Recommended Posts

Posted · UMS5 Pro Bundle - Print not starting

Hello folks,


we purchased an Ultimaker S5 Pro Bundle and started printing a few days ago. It is an late 2020 model (U on the sidewalls) running on the newest firmware.


Problem description:

When starting a print (or even XY calibration setup) the printhead moves to the front left corner. It loads the material and purges about 50cm of filament. I think up until this point everything is normal procedure. From here on out the printer continues to make strings of filament. It moves between front left corner to mid left corner and creates strings of filament until the print is aborted manually. The display says "PREPARING TO PRINT" and yellow status circle is about 25%.


All in all the printer seems to be very buggy. We have lot's of error screens and wired behaviours loading filament in the station. Sadly not very convinced at the moment. Above issue has to priority, as it brings the printer is a very bad state.

    Hi @Xpect, thank you for your message. 

    Have you tried not aborting the print manually and see what happens? 


    If I understand your description correctly it sounds like it is priming the print head, which can indeed take a couple of minutes and your print should start by itself with just a little bit more patience. The few strings of filament you should be able to easily clean up from the bottom of your build chamber at the end of your print.

      • 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
