Elephan Foot Issue

TAZ6 using cura
I have it with PLA, PETG and ABS got it better by reducing first layer temperature and flow rate but I got it to the limit.
Could it be a leveling problem?

Yes. Most likely a dirty nozzle or disc contact points causing the auto-level to miscalculate. The autolevel system is based on electircal continuity, so any plastic on the nozzle / discs will cause problems. Heat up the nozzle, clean it off with a paper towel. Scrape off any plastic on the discs. Replace or flip the wiper.

Imposible. All of those are clean on every print. Maybe a Z offset?

any luck yet
