The best way to check your tension for FMQ is to do a series of loops, direction changes etc. That way you will see if you're getting any eye lashing. I have a PQ1500s that was my main FMQ machine for a number of years and my experience with it was that I needed to slightly lower the top tension. I also tweaked the tension on the bobbin case depending on what thread I was using. You can use the same test for bobbin case tension for this machine that the handiquilter folks demonstrate for their long arm machines: load your bobbin into the bobbin case then hold the case flat with the open side face up (so you can see the bobbin), with your other hand pick up on the thread coming out of the tension spring and see if you can lift the bobbin case. You should be able to lift it so it is standing in your hand. If you can't lift it to stand, then you need to tighten your tension. If you can lift it all the way out of your hand and it hangs there without dropping down at all, then you need to loosen your tension. For my machine it worked best when I could get it to stand and feel a slight pressure on the thread as I pulled it up, but not so much tension that it lifted the case out of my hand. From there, try some stitches doing loops, direction changes (with points- like in a spiral in and back out) etc. on a scrap piece and tweak as needed.
Hope that helps.
