Fine First layer calibration
Hi! I'm new in this of the 3D printing, at least in the part of having my own printer and doing that stuff, I got a Prusa MK3S+, all the parts are the official ones except for the extruder.
I did almost all the calibrations I found for a starter, I reached the first layer calibration, which has been veery slow.
I started with someone like this: https://www.printables.com/model/9838-first-layer-test-60x60-mm-square-z-calibration
I'll use the printer for non-detailed things, and some very detailed things, so I take this assumption which could be wrong;
"If print with a small/fine height layer works fine, it will also works with a tick one too".
I'm not talking about the first layer calibration, is about how much fine will be each layer, I'm using ESUN PLA for this, and also I don't have the original extruder, so I can't use a lot of prints on printable (which comes as gcode), I need to generate the gcode for each one and I needed to choose the layer height.
After a lot of tests iterating over -0.1 from 0, between -1.9 and -2 is the sweet point, layer tower then -2 the surface becomes very rough, and bigger than -1.9 the printed lines of the layer are too far one to other, making the light pass through it.
So now..... how can I know which value between -1.9 and -2 is the right one? the samples -1900, -1925, -1950, -1975, are too similar to me, so I don't really know what should I look, or what to print to eval this, from the prusa oficial docs, any of the value is a "good value", is just... the range is so big...
Thx!

This is in the wrong forum ...
Run the built-in first layer 'Z' calibration and show us a picture of the result *on the print sheet*
Cheerio,

Hi, which one is the right one?
The built in first layer gives me the same result on that range... so no idea which value to use.
It's in the right place now.

Hi, here images of that test:
-1900
-1925
-1950
-1975
mm, from what I see, while lower the value, seems to get a better print, but also is so thin the first layer that the print is so hard to remove from the base.
The images also do not show very well, but the first line the printer does, do not print very well with values of -1975 for example, is so thin that part of the line do not print.
Seems each part has its good and bad parts.

Picture no.7 looks about right.
Try using that and if there are differences in adhesion in parts of the bed come back and we'll look at finer grained calibration.
Cheerio,
