Hey, I'm currently using a Ultimaker 2+ with Cura 4.8 and have difficulties with adhesion to the build plate. This has never been an issue before and I haven't change filament or anything. So, I've tried glue, higher build plate temperature, calibrating the nozzle, thicker bottom layer but not even one line will attach to the build plate. Please help if anyone has had the same problem. Could it be the now very cold room temp?
