Not to confuse you, but this post has nothing to do with the foot on your sewing machine. What it is about however, is how to get your piecing off to a good start. This simple tip applies when you're sitting down at the sewing machine ready to start sewing two pieces together.
I recommend that you always start by first sewing over a small scrap of fabric. Simply start sewing on the scrap, then feed your pieces in next (with their seams nicely aligned). It's okay if the machine takes a few stitches in between your scrap and the pieced items, as it won't harm anything. The potential thread mess will be on the scrap instead of on your piecing, and if your pieces are getting eaten by the machine, you can give a gentle tug to the scrap and help pull your pieces through.
It's nothing fancy, but I've included a picture. Happy Sewing!
