Might be frustrating now, but really ... isn't it absolutely exciting? I have a HQ Moxie that I learn something new every project! Excellent suggestions in this thread to give you some guidance. I checked on my "cheat sheet" for any ideas that might help you, and this is what I have:
1. Upper tension - if its too tight, your thread will break
2. Is your quilt tension too tight? loosen by 1-2 clicks & see if that happens
3. Poor quality - fabric, batting or backing
4. Is your foot to high? (I'm not familiar with your machine)
5.Thread quality, needle quality
And the practice of doodling on paper first is important to develop the muscle memory. When practicing swirls, curls etc. try lowering your stitch length, look where you are going not where you are at. Try them at different sizes too.
Hope some of this helps! I'm no expert and I have to remember to heed my advice!
