Does this look right?
Hi I just started printed on an I3 MK3 and I think it has problems with the first layer, but I don’t know.
when I’m trying to print 0,15 and 0,20 mm layer height, the nossle rips up the prints when I get to third layer, and when I start printing the first layer it looks like this:
And the cirkle looks pretty wierd
and if I take a closer look the brim looks like this:
is this normal?
RE: Does this look right?
No. Your live Z is way too high. You need to adjust it down (make more negative).
Follow the instruction here https://forum.prusa3d.com/forum/original-prusa-i3-mk3s-mk3-assembly-and-first-prints-troubleshooting/life-adjust-z-my-way/

Clean plate with dish soap.
Then adjust your z.
Normally in the first layer there should be no gaps.

Its Wierd cause now I printed the square with the exact same settings, and it looks much better, I dont know, could it be the filament? Or could it be my slicing skills?
RE: Does this look right?
I think it's your live Z skills,
that square still looks to have separate lines of filament instead of a single smooth sheet with all filaments squished together!

Joan is saying you need to go a little lower.

Guys, now I’ve printed this, and at the start (marked with a circle) the live Z is about -1.200 and the end in the opposite end it’s around -1.270. 
And throughout the print I slowly move “down” in Live Z but it has all these darker lines, and they looked like holes between the layer lines, so I kept on moving down and in the end it looks allmost see through, I don’t think that’s normal, what am I doing wrong? And yes, this is after I’ve washed it with dish soap. So guys can you please help me?
RE: Does this look right?
Try this process for Live Z

Setting in printer, set calibration to 7x7, is a lot better.
