Syptoms When I change the spool of PLA or PLA+ filament on my 3D printer or use the 3D printer after not having used it for a while, I am often having problems where the printer seems to be under extruding, where there is poor bed adhesion and where tuning the printer does not seem […]

Some of the 3D prints take a long time to print. Good bed adhesion is important: I purchased 2x 3meter length 25.4mm OD (1 inch) 1.2mm thick galvanised steel round tube from the local hardware store and 1x 1meter length. Round tube #1 (3 meters): 1064mm + 1064mm + 864mm Round tube #2 (3 meters): […]
