Support structure fails or has really bad quality

[Simdev22 0]

Hello!

 

I have an ongoing issue with cura since I started to use it. (Around 4.3) 

So when I print anything with support the support structure is so bad in quality that it has missing lines, stringing badly, little plastic bits lie around the print and most of the time the support is the cause of my failed prints. I don't know what to do or how to improve the support quality. 

Any help would be appreciated.

Hi, 

 

What material and with what settings are you printing this supports?

We used to have some issues with PVA (being to moist) we solved this with a filament box heating the spool up to 45°C and keep it there. we turn this box on about 2h before printing with PVA and it works like a charm.
