I have had the same experience with the same machine [Janome] I too gave up on it and went to my Juki for FMQ and never looked back! Love the Juki for most o my sewing and the Jan sits there.

I may try to finish this quilt on the Kenmore. I'll have to move things around and get some tables situated to support the weight of the quilt but that can be done. I'm just so tired of fighting with the Janome and so disappointed. Guess I thought it would be a dream come true. More like a nightmare! May call the dealer in the morning & talk to them; maybe they can help me sort things out with the Janome.
