Prime blob in front of camera


Recommended Posts

Posted · Prime blob in front of camera

I love Ultimaker and its build-in remote features.

As I work from home, I can start prints and monitor them remotely. Awesome!

I also like the prime blob. Its a quick and easily removable way of priming the nozzles.

My only peeve is that the prime blob for the right extruder is squirted out directly in front of the camera..

When I want to see how the print is going (especially the first layers), the view is largely blocked by a blob of plastic.

Can you please find a better place for the blob?

    It is not the best place you are right, but the angle of the camera is also not the best to view the first few layers.

    I use an additional webcam which is mounted above the printer, to see the print bed from the top which helps a lot to check the first layers.

    Hi! 🙂
    Here are two things you can try:

    The easiest and my favorite is placing an IKEA mirror inside of your printer. It's ideal when you are working from home or need to watch multiple printers. If you pause the printjob it allows you to see the full printjob even if you have just a few layers. You can also see the complete printjob when it is finished.


    A harder one is changing the Y position of the primeblob. You will have to go an hunt for the G280 in your ufp. These indicate the primblobs. In the line above it you will see a G0 and movements to a X Y Z coordinate, for example: G0 F9000 X311 Y6 Z2. If you change the Y from 6 to 30 it will move the primeblob a little to the back as in the most bottom screenshot. 

    Here are instructions how to change the gcode in your .ufp file. 



    You can load the finished .ufp in a digital library project and sent it from there to your printer. You can also load it on a USB or back into Cura to sent it to your printer. 

    Honestly, a mirror seems to be your best option 🙂

    Good luck!

    Oh yes the mirror solution, I forgot - great workaround! 👍


    @Molgineer No, that's just a webcam, which is not integrated into the DF. Depending on which model/brand you buy you have different possibilities to access it from home. But check the mirror solution, I like such things 🙂

      • 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
