What's wrong? My prints are stringing...
I built the Prusa MK 4S, but the quality of the prints are not so good (see picture). Can someone tell me what's going wrong here? My prints are stringing... My belts are oke (I thought that was the problem). Do you know what I can do to fix this? Thank you in advance...

The stringing is probably damp filament.
If your belts are at the correct tension then you might have misaligned the grub screws when fitting the drive pulleys to the stepper motors.
Step 26 on https://help.prusa3d.com/guide/3-x-axis-x-carriage-assembly_707749#724263 - and the equivalent on Y.
Cheerio,
