Oh my. Not 1 but 2 machines acting up. That is a frustrating day.
How frustrating and most likely right in the middle of a project!!Have you tried cleaning between the tension discs? (A crisp new dollar bill"flossed"through sometimes does it.) You might have some bad thread, too. I once took my machine in to the repair shop because it was stitching so bad and they tried everything, finally they took off the thread I had left on and tried a new spool-miracles do happen it stitched beautifully with no repairs needed! So. just step away for awhile and come back to it later.
Thanks, I did clean it with some floss and rethreaded it. It finally allowed me to finish my project and my BFF children love their gifts ;D *2U
I too like for things to run smooth. I get so nervous when something doesn't work right. I know I shouldn't let it get me down, but I do. Sorry you're having issues and I do hope things straighten up and act right real soon.
I guess this is how my machine let me know that it misses me for not touching her in over a month or more ;< ;D *2U
