Congratulations on your new Bernina! I have the 150QE and just recently gifted myself with the 830. They are overwhelming, but my dealer is fantastic. I did take the beginning class which included threading, cleaning, etc. but I go in frequently and they demonstrate whatever I need. I've never had an embroidery machine, so that's a HUGE learning curve. U-tube is FULL of demo's which are amazing. My suggestion - leave both machines set up if you have the room. Tackle one issue at a time and get comfortable with it before trying another.
