Help with problem print

[lukas.aurarum]

I had this model printed on my main printer and got this thicker back appearing on surface.
i then turned on pressure advance and print great

i got a second printer that had a marlin board which printed the same model fine.
installed duet, and printed the same band.
so i turned on pressure advance, but the band is still there.

all printers are direct drive.
just can figure it out, any suggestions?

Solved.

Was due to Maximum speed and acceleration of extruder not set high enough.
