Great Demo, I have used Industrial plain sewing machines for 40+ years and didn't know about a needle feed, my understanding form this is, normally a needle just goes up and down, it doesn't usually do a revolution like the feed dogs. Very Impressive. Patchwork/bagmaking would love it. Thank you sew much.
Hello! Have you had issues back stitching with your needle feed and breaking needles? I am sewing a small amount of layers (2 knit layers) and breaking needles in reverse stitch.
