I've seen several videos demonstrating how you can hold the needle up/down button to make several small stitches at the beginning or end (preventing the starts and stops from coming undone). I have an older HQ16 (purchased used) that does not seem to work this way. For each hold of the button (no matter how long) the needle goes up once or down once, only.
Is this fixable?
This leads to the question...can the software on my machine be updated?
I do not have a stitch regulator (although I don't see why that is relevant).
