Can't seem to add Support Blocker - Cura 4.9.1


Recommended Posts

Posted · Can't seem to add Support Blocker - Cura 4.9.1

I might be going a little crazy, but I can't seem to add a support blocker.  The aim is to set certain sections of my print to 100% infill, whilst have others at a standard infill.

After I select the model, then press Support Blocker on the Left hand pane and press the image again, I don't get the box appear.  Am I doing something wrong?


Here's a screen recording of what I did: 



Am I going mad?

    I should have done this earlier, but resetting Cura by deleting everything in the config folder and starting again fixed this problem.


    1. Help Menu -> Show Configuration Folder

    2. Quit Cura

    3. Delete everything in folder

    4. Restart Cura

    Well it fixed it for that session.  After a restart, it failed again.  Looks like it might be related to the issue where the Model can't be selected by clicking on it that others have reported.
    When the issue is there, you can't just click on the model, it won't become selected.

    When the issue is not there, you can click on the model, it will select, and then you can click on the other things like the support blocker and it will work.

    ok, progress.  Issue is really around not being able to select the model.  When Cura is on my Macbook's primary screen, everything works.  When Cura is on my secondary screen, I can't select the model by clicking on it, and hence can't place the blocker.

      • 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
