Issues printing with Printcore AA 0.8 : Strange Elephant Foot

[V3DPrinting 3]

Hi to all

 

I am trying to print with a 0,8 mm nozzle on my S5, using Cura 4,0.

 

I have used the printcore AA 0,8 profile and printed a calibration cube in PLA, 200 microns resolution

 

I have done some tuning on the temps (nozzle and bed) and material flow, but whatever I set, I still have an elephant foot on all the solid infill layers.

 

So the 5 first layers are consistently at 30,5 mm for a cube of 30 mm side, for the rest of the layers I have a 30 mm +/- 0,05 cube.

 

See picture

 

 

Thanks for your feedback

I forgot to mention that printing with a 0,6 nozzle with a profile derived from the AA 0.4 works fine, no elephant foot at all.

And yes, I am using 3D Solex Hardcores, so I am able to swap nozzles.

 

Also I have noticed an excess of material on the top layers 

 

Has anyone a clue ?

I have recreated one in the Cura section, which is more appropriate.
