Weird behavior of Tab+ extension


Recommended Posts

Posted · Weird behavior of Tab+ extension

Because os the height of 105mm of my vacuum nozzle, decided to use Tab+ to get a better adhesion to the bed.

In addition, I had chosen 5 Brim Lines.


During printing the first layers I was surprised that the tabs, printed outside the Object didn't have contact to the object as wanted.

There was a gap of approx 5mm between the outside tabs and the object.

Thatwhy the tabs have been totaly useless.

Also this tabs have been printed very thick, which wasn't neither intended nor wanted.


Despite this, the object had enough adhesion to the bed, so the print was finished succcesfully, as you can see in the picture.


I guess, whether I made a mistake with parameters of the Tab+ or if there is an error in the Tab+ extension.

Comments welcome.


Regards Gerhard

    Even if you should not use the Tab in this case ( no need to use it) it's certainly an issue with your settings . On a basic similar case there is no issue.

    Yes looks like a Bug or a Feature ? Don't know how the developpers of Cura will consider this result coming from Cura 5.3 Beta.  


    Unchek the option "Brim Replaces Support"  to temporarily solved this problem.


    This new behaviour looks like linked to this Parameter + a New one Call Brim Inside Avoid Margin.

      • 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
