Hi all, I did the setup procedure and printed the first layer severalt times. At least, my z-correction ended up at -1,25 (-0,2, -0,35, -0,7, -0,9, -1,1, -1,2). First layer looked quite well, then printed 3dbenchy and the nut from the stick, using the filament in the package (PLA Galaxy black). No more adjustments:

How can I fix this?

Hello,

First please use the forums options to upload your photos since some people don't like using external links. Just use the Add Media or insert image options.

Second can you please explain how your prints ended up like this? They came out of the printer like this? The layers did not adhere to each other? What happened?

It looks like the prints went under some kind of stress but from the photo I cannot understand.

This does not look good... what filament you print with? Aren't you printing PETG with PLA temperatures by mistake? Isn't AC or fan blowing directly at printer while it's printing?

First sorry for linking the picture...

Filament: PLA Prusa Galaxy Black (sample in the box), 210°/60° as stored in file on the USB-stick. Maybe the problem was an open window... I have to test ist again when I open the PLA-Filament roll i ordered.

with the second sample (silver PLA from Prusa) and files, i sliced in prusa slicer, all went perfect!

 

The first prints came out looking very well too, but only a tiny force destroyed the structure because the layers did not adhere to each other.

For my new prints I choose 215° and 80% cooling, problems are solved 🙂

Is there no way to edit my first post to embed the image there?

Sadly no, there's limited window of few minutes when you can edit your post, then it stays there forever. 

Those prints look like they totally lack layer adhesion. This can happen when printing too cold, or when heavily under-extruding, which does not seem to be the case. Unless the sample is not PLA by mistake.

Unfortunately you cannot edit your post unless you do it in a few minutes.

Like crawlerin said if the layers did not adhere its most probably a temperature issue. Otherwise your prints look good. Maybe it was a case of bad filament? If your other filaments are having proper adhesion in the proper temperature then it's probably that. Hopefully all goes well from now on.

Cheers.
