I do have the feeling you would need to change the Arduino file quiet often,
As the servo isnt precise every time,
It will almost always be Print able, But i do notice that when i switch from ABS to PLA that PLA has air between lines,
Its still print able, the next layer will be close to perfect, but its just something i wanted to say, that this isnt something that will be once set, always good to go.

Example today, I had it perfect for ABS, once i switched to PLA it was like i said earlier, a bit to high.
