Bed adhesion
I have two K1 Max printers. I have solved just about every printing problem I have had except for bed adhesion. Some of the time the glue that I got from Amazon works but most of the time it does not especially for larger prints. Is it just normal to have to glue every print down. If I use no glue the filament does not stick. No matter what I use, pla petg Asa whatever. If it is normal what kind of glue do you buy?
