"Ultimaker S5 with its custom-engineered Material Station and Air Manager, now you can transform your office 3D printing workflow with automated material handling, optimized air filtration, and filament humidity control."
The purpose of the purchasing the S5 pro bundle was that this system integrated a filament humidity control. Maybe the pva that came with it was compromised? However the case, the room in which this sets on, does not receive humidity and with the added humidity control on the system in itself I figure the pva would not brittle. I ended up tucking away the pva filament and using the breakaway.
