Well, if these WFs don't work right when the feed dogs do not align, then please explain to me why the one I have works.
It appears that when I state an experience contrary to the accepted norm I'm either ignored or accused of trying to argue. Neither is the case in this situation.
I currently have a Singer Slant Shank ZZ Even Feed WF, a Singer Low Shank ZZ Even Feed WF, and the generic Low Shank ZZ WF. The generic one works as good on the straight stitch machines as the Singer units work on their respective machines.
That is MY experiences with them. Not an argument, a fact.
As far as typing in all caps to emphasize being offensive and considered yelling ... to bad. I wouldn't have to go to the trouble of emphasizing things if people would read and comprehend what I wrote.
Their problem, not mine.
