Anyone knows how to fix the issue with my 3d printer? Basically round object a no longer round. It happened during the print. I thought this was a slicing software bug so I tried to print something simple just for test and again a circle is an ellipse now (see photos attached) Anyone can help I’ll be much appreciated.
P.s my printer is Anet A8 chinese Prusa i3 clone. It is two years old now and I never had any issues.
the belts are too loose.

Thanks for your replies. I have checked the belts, tightened them up and still the same problem. I’ve tried to print the 20x20x20mm cube and the result is 22x20x20. So there’s something wrong with the x axis. Swapped the stepper motors but still the same result.
Could it be that the x axis driver has gone faulty?
seems to be non linear. 71.9⇔75.7 (3.7) 71.4⇔75.1 (3.8) 20⇔22. (2). If an error of 1mm per cm happens this should be around 7 not 3.5 on the 75mm part. So the error gets less on bigger parts. All software or mechanical reasons should be linar. So maybe you loosing steps or something is not fixed anymore and bends dynamically. Also check your G-Code to ensure it is not some compensation Slicer setting. Also printing a Matrix (16×16 squares each 1cm only 1-3 layer) could help, to see if position changes the behavior.
Maybe there is some dirt (plastic leftovers) in the groove of the belt or pulley.
