S5 Issues - Print Pause Blobs mid print


Recommended Posts

Posted · S5 Issues - Print Pause Blobs mid print

Hi UM Team, I have a brand new S5 that has been commissioned this week. 

- Latest Firmware Installed

- UM Tough PLA in Print Core 1 using 0.4AA 

- UM PVA  in Print Core 2 using 0.4BB


Three main issues I would love your help with: 

1.0 Print Head Pause Blobs 

The printer seems to be pausing mid print and continuing to deposit a blob of plastic whilst paused before moving on to continue with print. It is even doing this pause/blob deposit during XY Head Calibration sequence. (see large black PLA blob in forground right and clear PVA blob in back zone of the Y calibration grid. 



On an actual printed part you can see the pause blob has returned part way through print raft support layer (bottom arrow) and then again 3/4 way through the print (see top arrow) 



2.0 Auto leveling Sequence 

It never seems to fail on XY Calibration when it does the array probe sequence but before prints the printer will get to almost the end of the pre-print probe sequence and then give an Auto Level Fail notification. Then when I simply hit retry it more often then not gets through the test probe sequence and successfully prints? 


3.0 UI Glitchy, Freezes, Non responsive 

I have noticed that the UI sometimes hangs between screens, sometimes does enable action buttons to be blue ready for input (the sit on screen in grey passive mode for a while) and when you press the up and down arrows on XY Calibrate the software will beep to recognize the input but NO action is transferred to the bed level adjustment drive? 


Any help on fixing these issues would be greatly appreciated.

    I suspect the usb cable that communicates between the two computers.  I'm thinking that the arduino is getting errors and asking the linux box to resend the gcodes thousands of times until finally a proper gcode gets through.  You should dump the logs and post them to your reseller but I suspect you will have to return this printer to have it repaired.


    There's a menu option on the S5 to dump the logs to a flash drive.  Then you can look at the logs or just email them to your reseller.

      • 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
