Supports not being generated for the whole model - Cura 5.5

Posted · Supports not being generated for the whole model - Cura 5.5

I am slicing a model that has three structures that need supporting - but Cura is only generating supports for one of the structures.  I have tried using support blockers and using per model settings to tell it to create supports but this doesn't produce anything better.  have tried Tree and Normal, both produce the same result. Not sure what is going on.

    Check the settings for "Minimum Support Area" and "Minimum Support Interface Area" and "Support Overhang Angle".  You look to be supporting inside diameters and they narrow down at the top.  Both a lower Minimum Area and a an angle around 45-50° should allow the supports to get to the other outside one.  For the middle it's an ugly reach.

    The best idea is to use Normal Supports - Everywhere.  It looks like that model only needs support within the holes.  If that is true you could probably get by without any supports (provided your layer cooling fan is up to snuff).  I don't bother with supports in holes that are less than 20mm diameter.

    Thanks for the help. I will check these settings. I did try normal supports and the same thing happened - only one support generated.    Strange this is that this morning I revised the print temperature and build plate temperature down by 10C and switched off the fan (it was at 10%) and re sliced,  tree supports were then generated for all three holes.  I’m using ASA, it’s recommended not to use a fan so supports are required.  Will switch back to normal supports.
