My bobbin screw has no settings, so I like the idea of marking the starting point with a Sharpie if I mess around with it. Hubby did the same on the timing belt. He marked the shaft and the pulley so he could tell if it shifted.

If I was using an older machine I would let a pro get it perfect for everyday sewing and write down all the settings and then go back to those after doing adjustments for a special project. In home-ec in my day we would get our hands smacked with a ruler if we touched the tension disk knob!
