I tried to understand the reason without result
The walls of the piece are 2.5 mm
my settings are nozzle 0.6 layer 0.2 filament 1.75
I tried to substantially increase the amount of material to be extruded
Extrusion multiplier 1.30
and I have also decreased the speeds but it always seems that the pla is not enough, besides to this touch it seems that each filament is untied from the other
I tried to increase the temperature without getting any results
Do you have ideas? parameters

How thick is the bottom flat section? The number of solid layers you can fit in there will greatly help with this. Also, outline overlap will help with the infill not bonding to the perimeters. As the thickness seems to fluctuate I'd think that your build surface is not entirely level. I'd consider a raft for solving those unfixable hardware conditions.

First is this really a 0.6mm nozzle?
Second if you have to run the extrusion multiplier up that high then obviously something is wrong.

What is the print speed?

thanks anyway for the help the problem seems to have been related to the extrusion whidth
the always left in automatic I don't know because it was in manual at 0.8 so I put again also the extrusion multiplier at 1.05
however even in automatic it does not go well maybe it is a bag
setting it to 0.6 the printing is fine without problems
