Bad supports for anyone else?

Posted · Bad supports for anyone else?

With Cura 5.1 I have noticed poorly generated supports on all my PVA supported prints. 
PVA parts are printed in the air and the support interface has several gaps in the top layers. 

 

I have already reported this as a bug on github, but haven't seen anyone else experiencing this problem yet. You would think that this problem would be noticed more often with a printer that is designed for PVA printing, among other things.      

 

Bad generated support structure · Issue #12839 · Ultimaker/Cura (github.com)

 
So I just wanted to ask if anyone else has noticed this problem. 
Unfortunately, this problem means I can't do anything with 5.1, while 5.0 still has some bugs...

I see that the Cura team has this on their backlog.  

In the case of that Github model there are settings you could adjust to move the support structure away from the model a  bit.  That way it wouldn't try to support those small upper radii that are the problem.  Changing the minimum XY distance from .2 to .6 will help as would lowering the amount of horizontal expansion and changing to "XY overrides Z".

 

I found another problem on certain models as there is no retraction when moving from the support to the model.  If the layer start point is directly adjacent to the support exit point then the model and the support can get welded together.  Not an issue for you with the PVA but for single extruder printers it is an issue.

      • 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
