This may be a question that has been answered before, but I was not able to find an exact answer to our issue.
We just got an Ultimaker 3Extended and are trying to print with PVA and white PLA, but are not able to print successfully with the PVA supports. The print always comes out with fly away print "hairs" and the PVA material interrupts the PLA print, ruining the finished product. Below are some example images.
We've tried reducing the PVA suggested temperature by 5 degrees to 220, and set the retraction distance to 6, but neither seems to help. Could this be an issue with the reel being exposed to humidity?
Any ideas or suggestions would be great, and thank you all for your help!
