Trouble printing after changing to a different PLA
Hi - new 3d printer user here. I am a high school teacher and bought the Prusa i3 MK3S+ this year and just finished the roll of PLA it came with. We had extra PLA from a previous teacher so I reloaded with that. It is not Prusa brand - it is 3D fuel Pro PLA. It was fine for a while, but I am now having trouble with my prints - see the pictures for reference. I am using the default PLA settings. Any idea what settings I might have to change to get a better print? Thank you!

Two things I would quickly check.
1. Be sure that your Z calibration is spot on. Some filaments are more finicky than others.
2. You might try drying the left-over spool, particularly if it has been exposed to room air. A food dehydrator works quite well, or, lacking that, an electric (NOT GAS) oven set low, to maybe 120-130F (49-55C).

Ok checking back in - I was able to successfully print the parts. I turned off the printer for a while, then turned it back on and cleaned the nozzle. After that I used the Live Z adjust and changed it from -1.400 to -1.415 which didn't seem like much of a change. I didn't have access to a dehydrator. That is the only thing I changed - see the images for the results.
I did seem to have some warping and a line form on one of the parts. Let me know if there is something I should do differently to fix that. Thanks again for the help!

That line you see is also called 'buldge'.
