Hi there,

 

I've got that following issue with cura 4.3 (using Ultimaker S5 Printer)

The model i want to print is standing on 4 feets (as you see in the screenshots below)

 

Model 1:

Model 2:

Now.. the base of the model which stands on the 4 feets obviously needs to be supported.
Im working with the standard printer settings except the support structure setting, with is set to

 

Generate Support: YES
Support Extruder: Extruder 2

 

The first layer of the models base is layer 20. So the last support layer is layer 19.
I expected the layer 19 to be a "full" printed support layer (so that the models base is supported correctly).
What the cura 4.3 slicing output is, is the following screenshots (model color: red).

 

cura 4.3 layer 19 (what the..?!):

With cura 4.1 i installed a later version and sliced again with the same settings (pic 5, model color: green)

 

cura 4.1 layer 19:

So .. is this a known issue? Are there any mistakes i did?

 

Thanks
Timo

    Hi everyone,

     

    Update:

    - the problem reacts to the setting "Support Horizontal Expansion"

     

    If i slice my acutal file with the following settings, i get the following results

    0   =>   no print on air

    1   =>   print on air

    2   =>   print on air

    3 (default)   =>   no print on air

     

    For my initial post, i'm 100% sure that i used the default settings

    For my last post on feb.27 im not sure about the "Support Horizontal Expansion" setting

     

    So now that i described the problem and even served a possible solution, i hope for some more reaction.

     

    will keep you updated...
