I've been having a blast with my EggBot Pro but have run into an issue that's a headscratcher because it doesn't always do it.
Every so often I find that designs printed on spherical objects come out stretched when they weren't stretched before. For example, a circle will come out as a circle when it's working, and when it's not, it will be an oval.
I've been switching between two types of objects - Christmas ornaments and ping pong balls. The pen motor is in the top most position. The three things I change are the horizontal position of the pen motor, the height of the pen arm, and the position of the egg coupler.
I'm thinking that one of these things is perhaps causing the problem and that I'm not putting one (or more) of them in the right spot every time. Or it's something else in my setup that I'm messing up.
Any ideas what might be causing it? I've wasted a few things accidentally or on purpose and would love to get some sort of direction to focus my testing on.
I did try printing the circle/square file as suggested on one of your
wiki pages. It came out oblong/rectangular on the ping pong ball I was
testing on. I fiddled with settings on the machine to no success.
For what it's worth, here's my setup:

Thank you for your time!
