PLA won't stick to the bed
I have an i3 MK3, and the last few prints have not stuck to the bed of the printer. This is a new problem. How can I get the prints to stick to the bed of my 3D printer?
RE: PLA won't stick to the bed
There are 2 primary reasons filament won't stick to the bed, your z-offset is too high or the bed is dirty or both. If you're using the textured sheet, PLA doesn't stick as well as it does to the smooth sheet so your z-offset and cleanliness are even more important.

RE: PLA won't stick to the bed
I have found printing with a few raft layers helps, even for prints with a large contact surface. I have a non-textured bed and clean it with alch between prints. However, I had this issue even with a fresh clean bed. I noticed this when I printed bases mostly. For example when I am printing what is essentially a 3mm high by 48mm wide cylinder, the 'model' would sometimes release and get marred (possibly due to some warping). However, when I added a raft, this issue went away completely.
