Support Material for PA6-GF

I’m attempting to find a solution for support of a long print in PA6-GF. I tried using dried PA Support on test prints and it is difficult to remove at 0 Z interface, moving to .08 makes the model surface rough.

Research led me to ASA as a support material and that worked great for shorter prints. Thinking I had it solved I set up a print overnight and the prime tower failed about halfway through. It seems that the exact settings that allow ASA to work for short prints, are not great when applied to a long print – the tower warped and delaminated resulting in spaghetti when priming and a stopped print this morning when I woke up.

Any other suggestions?

It looks like your prime tower warped and split along the weak lines.
Did you try to increase purge volumes to the point that no mixed material is part of the tower anymore?

Edit: Sorry braintwist. Did you try with very large purge volumes and no prime tower?

I have not tried that but I will give it a shot. Thanks for the suggestion.
