First couple of prints having defects

First time printer here, I've run into issues with my test prints in that the first several layers of a print turn out with terrible alignment and other defects (see pictures). As the print progresses, the quality improves substantially, but a few bad layers spoil the entire thing.

Closer looks at Exhibit A, bottom layers shifted off to the side along the Y axis. Curiously, the top of the print is of very good quality.

Exhibit B, bottom side of the Batman logo from the SD card that came with the printer, again featuring a defect on the bottom layers. Again, the top of the print came out pretty much flawless.

Nozzle is 0.4mm, first layer height 0.2mm, regular layer height 0.15mm, infill 20%, filament PLA that came in the package. Printed on a MK3S+.

RE: First couple of prints having defects

It's often times difficult to tell, but at first glance, particularly of the Batman logo, it looks like your Z calibration may be too high, as in not enough of a 'squish' factor.

This can cause or aggravate adhesion and 'curl up' issues.

RE: First couple of prints having defects

Hi;

   as @jsw mentioned the Z height seems to be your issue, check this article https://help.prusa3d.com/en/article/bed-level-correction_2267/

   And just print the test model : https://www.prusaprinters.org/prints/36706-bed-level-test

  maybe post your result , then one can see if your Z height looks ok overall.
