Circle turns out like a football

tryin g to figure out why when I try to print a circle it is all distorted and urns out like a football. That is north American football. Tried the trouble shooting hints and no change.

Try looking at think link.

Thanks I will give it a try. They seem to be moving well but for now it is not working.

Thanks again

Check that the toothed belts are tensioned.

But not too tensioned like explained in the Wiki.
