Thank you misan! The pulley was a little bit loose on the y-axes after a new wizard the circles are in perfect shape!

I would check for loose pulleys on X & Y axes motors.

And check belt tension too: https://help.prusa3d.com/en/article/adjusting-belt-tension-mk3-s_112380

Hello everyone!

I am new to the community and I'm having issues with my MK3 printer. It has been working for approx a year without issues, but suddenly it makes weird patterns in the printing. I tried making some circles to test it out and I get this weird straight pattern aligned around the circles.

I can't seem to figure out what the issue might be. The belt's tension is 255 y-axis and 257 x-axis so the belt should be in the correct tension span.

Printing is PLA 215/60 Quality 0.15.

The circles are just for testing this issue also interfere with other prints.

attached some photos for reference

Thanks in advance :)
