I just noticed something on my sew Viking SM and I think it helps explain why some of my seams are off just a bit.
It's my feed dogs! If I just let the machine do the work and even with a "little" bit of positioning, my feed dogs tend to pull the material to the left. Tried it again and again and, yep, the same results.
And here all this time I thought it was me ass this time. :) My feed dogs must not be positioned/ tighted/installed correctly and so they're pulling my fabric just enough off kilter so that me seams are the same from start to finish.
Any one else notice this problem with your SM?
