Looking for some assistance with an issue I am having with circles. They are not fully round, but slightly Oval. It seems to happen to either small and large diameter circles. Here is a check list troubleshooting that I have done.

1. y and x axis belt tight (check mark)

2. y and x axis stepper motor set screws tight (check mark)

3. y and x axis pulley across from stepper motor tight (check mark)

4. y and x axis stepper motor mount bolts tight (check mark)

5. Build plate mounting bolts all tight (check mark)

6. y and x axis rods tight and not bent or warped (check mark)

7. y and x axis belts have all teeth (check mark)

8. bolts on extruder mount and holding plate all tight (check mark)

I don’t know what else to check as hard ware that might be causing this issue of the circle being an Oval.

On another note I am running Slic3r ver. 1.0.1 and I am also running Repetier ver. 0.95f  
this was also happening when using pronterface (new ver).

Anyone have a clue as to what else I can do to stop this Oval?
