Stitch Regulator table 7 series ruler work

I became used to using a stitch regulator built in a table on my Q 16. So I thought I would try this for my B770QE I use for when I travel. It worked very well for my needs and I would buy again.

So far my experience is hit or miss. Sometimes when I sit down the stitching is great. Other times I can't get it to move.

The table is great. It fits my machine perfectly. The instruction sheet on how to attach the BSR is not great. It says refer to the pictures but they all appear to be not quite in focus stills and it took me a while to figure out what order to attach it with the included hardware.
