I just tightened everything and the egg is secure between the couplers. It looks to me like the pen is deliberately drawing the wrong shape. The movement of the pen arm is not a perfect circle.
Everything did feel solid to my knowledge. Unfortunately I do not have the eggbot right next to me at the moment. I will double check that everything is tight tomorrow. Do you have any other ideas?
