Eyelashing is operator oriented more so than any other reason.
As ScissorQ suggested, try slowing down your movement of your sandwich and/or speed up the needle!
Did you try the other thread that was suggested to you by your dealer? Try it ... and then when you go back to them, you can at least say you did what was suggested.
If you can't sort it out yourself, ask your dealer for a FMQ lesson. And stay there til you feel confident in what you are doing.
