Just a Public reminder that if you begin to have multiple issues such as loss of bed adhesion, stringing, blobs, or any common 3D printing quality issue; consider swapping nozzles.

Always try basic troubleshooting first, but I recently had an Ender 5 which still printed; but I would get random blobs and quality imperfections. I took the nozzle off for cleaning and installed a new one, and the prints are back to flawless.

It's not always in the print profile, if your nozzle hasn't been changed in months consider it! Don't use cheap nozzles, buy genuine E3D or OEM.
