Space prob  

Your filament is wet.  This might not be the only problem.  Dry your filament and try again.  If problems continue, come back and show us new pictures.

Hello, 

I have print with my Prusa Mini plus and my Bambou lab A1, and the result with the same filament. https://photos.app.goo.gl/JDNdRDuuDHUaj1Uv5

And you can see wave on the back of print. I was do the file gcode 3 time and she does the same print.

What do you think, can you help me?

Thank you.

Dry your filament between prints.

You may have a partial clog, try a cold-pull.

If you continue to have problems save your project as a .3mf file

Files > Save Project as

Zip the .3mf and post it here. It will contain both your part and your settings for us to diagnose.

Cheerio,

RE: Space prob

To me the pictures look like either a partial clog on the nozzle, or the extruder is not able to push the filament correctly, not a filament issue.

Have you tried to take the extruder appart and clean it? And perhaps take a needle through the nozzle/ do a cold pull.
