Can't print true circles?

Ok…still ironing out bugs with my Ender 3 V3 KE…for some reason I can’t seem to print a circle. I did a test on a cylinder calibration print, and you can see in the picture it’s oval. This is also true for 28mm mini bases…they all seem to be oval and not circular. Is this a slicer software issue? Or mechanical?

That is likely mechanical. It is likely calibration or belts.

K I will check the belts…I calibrate before each print…I’m assuming that should fix any issues in that regard?

I mean calibrate the extruder and movements. Not just bed levelling.

This might help.


Yes I second this opinion, give the calibration of the axis a shot and snug everything up!
