Best ways to tune your X-carve

I realize there are several threads on tuning your x-carve and they are relevant to the newest edition, bit I was wondering are there good test pattern files to help you make sure you X-carve is working properly and directions on how best to fix it. Or what are the way folks test and diagnose their X-carve.

The is based on posting a project earlier this week where folks were able to say something was loose (which the best needed to be tightened). I wouldn’t mind figure out a good way to make sure everything is working as it should.
