  1. I'm using an UM 3 extended and I'm having problems with PVA. I found the material in my institution and I think it was not properly stored. It has been in a room for months, not in a sealed bag. I did a hot and cold pull to clean the print core. I noticed grinding, so I cut off the last part of the material. When I print with PVA as support material sometimes it does not come out at all, other times it is not uniform, as in the pictures below. Is this a problem with PVA? Can I do something to make the PVA usable again? Thanks in advance.
