Oozing
My printer (an MK3S+) oozes a lot when it is heating up and, when it is doing mesh bed leveling before each print. As a result, blobs of filament get stuck to the the nozzle during mesh bed leveling before each print. This is causing the filament that the printer extrudes to get stuck to the blobs of filament on the nozzle making the blobs even bigger. Any advice? Please let me know.
UPDATE
I have seen some people modify the start gcode to make it so before the print, the nozzle heats up to a lower temperature eg. 160 deg. and then does mesh bed leveling and then heats up to the full temperature. If you think that I should try this then please say so and provide the gcode for it (I am using the latest version of PrusaSlicer: 2.3.1 and the latest firmware version: 3.10.0).

Many of us have found that a "2 step" warmup procedure resolves this problem. The basic procedure is:
- Warm the nozzle to a "no ooze" temperature (I used 160C). This softens any filament stuck on the nozzle so it doesn't damage the PEI during movement.
- Do mesh bed leveling (MBL).
- After MBL, home nozzle and heat nozzle to full print temperature.
There are many variations. I've got a documented example here that you might find useful.
FWIW - Prusa has implemented something very similar for the Mini startup gcode, so it's considered a viable approach.

RE: Oozing
I'm fairly new with all this but I had a similar problem about a month ago. I solved it by using the (nozzle file?) to clean out any residual filament that formed a minute chunk within the nozzle that was causing the filament to flow out incorrectly and come out at a slight angle which was sticking to the outside of the nozzle. That or change the nozzle head but I've found changing nozzles is a real hassle.
