So, I think I was able to adjust my first layer.
regarding the belts I think they're ok, after calibration I got this results: X 262 Y 280
By the way I'm not satisfied by the print quality. I got better results with my old Ender 3 without so much tweaking.
Don't get me wrong. I got a Prusa for reliability, now I can start a print and forget it till it's done and that's great.
But quality is still a problem.. hope to improve it..
The most work you need to do is in the slicer, not printer in your examples.
1. The ringing is because of the speed settings. Reduce it to get better results. MK3 is direct extruder with heavier head than Ender 3.
2. Adjust seam position, reduce extruder multiplier, adjust retraction settings to get better looking seam. Try also other slicers. Every slicer handle it something different so you're getting different results for different objects. Sometimes is Slicer A better, sometimes B
3. Use other filament, reduce layer height, play with temperature settings, improve cooling for this first layers
All of your examples are actually standard examples showing limits of FDM printing. You can have it on any printer and you can improve them on any printer without any hardware modifications. But you have to put time in it and understand the root cause of it.
