Make sure to test with both PLA and ABS at a variety of temperatures. The hotter the extrusion, the more liquid it is and more obvious the vibration artifacts will be. Also, PLA is much less viscous than ABS. Test with a variety of colors as well. Semi-transparent filaments tend to hide the vibration artifacts rather well. As do matte and very light filaments. Glossy black and opaque silver work very very well. Mind the X and Y orientation when slicing - having the labels correspond to actual X and Y axes will make debugging easier.
