  1. I just read the directions and it says yes the moisture can be driven from the PVA. I'll just follow directions and see what happens.
  2. can the spool be dried out somehow or is it not recoverable once exposed to moisture?
  3. I turned the flow sensor off and ran the print overnight, sure enough I could see in the morning a problem with the PVA. It's still running now, and has another 4 hours to go. The PVA is stringing all over the place, and I'm sure its because of humidity. The reel has been sitting open for a week mounted to the back of the printer.

Should standard procedure be to unmount the reel every day and store in a bag with th
  4. it happened again- see pic. below. I think my all-night print will not go through...
  5. Our S5 was in the middle of a print when it stopped with the message that says one of the filaments is out, and to put a new one in. However, there's still plenty on both reels. One is PVA and the other PLA. I simply pressed "ok", and it started printing again. What could cause this ? Thanks
  6. I tried it again and it worked for both printers. This time I used the UHU stick. Do you think that was the problem? Or something else I should be aware of?
  7. We have two new Ultimaker S5 machines, which comes with PLA and PVA. When doing the XY calibration the X calibration patterns is present for both PLA and PVA, but the Y pattern there is only PLA. The PVA is not printing in that direction. This is happening with BOTH new printers. It is not humid and the materials are new straight from the bag. Any thoughts?
