This machine should tell you if you forgot to put the presser foot down.
When I FMQ my speed control is way down near the bottom range. This keeps my "lead foot" under control as I tend to speed up on curves, causing those eyelashes.
I also put my stitch length to 0 rather than drop my feed dogs.
On mine, it always runs around "4" for FMQ, but that's neither here nor there as all machines are different.
Also, on my machine, it doesn't like it if you have different thread in the top and bottom. I know you're trying to show the problem here and that's why you have two different threads, but mine acts funny when you do that, right off the bat.
