Hello guys!
I'm a freshman of designing a 3d printer.I'm really interested in a printer work with wheels so It took me one month to design a corexy.But i have a strange problem that confused me for a long time.When it is printing a square or something else everything is good but when i try to print a circle It will change into a oval.This problem is not obvious when the circle is big enough for example a circle with 20mm diameter,but the thickness is not even and the outside surface is not smooth enough,I can see that surface is consisted of many lines.I don't think this was caused by the gcode file because it's normal when i use the other machine.I have tried many ways but seemed useless.I really need your help.Looking forward to your reply abuot any suggestions,thank you.
