Hi everybody, I just got my hands on an Ultimaker 2 sitting in an attic for about five years, together with several spools of PLA filament. After some cleaning and greasing I got the printer to print again, but I do have problems with the bottom layer, it has space between the lines of PLA. Bed adhesion is good, I leveled the bed again and let very small room between nozzle and bed, but still got the issue.
My question is: Can this be a result of the material which is over 5 years old? Does PLA age?
The top layer is of good quality, no holes in there.
I just want to avoid to spend to much time if the solution is to get rid of all the old PLA.
Thanks, Chris
