Ive had, Bernia, Janome, Viking and now Brother embroidery sewing/embroidery machines. There are just too many places things can go wrong for me to blindly trust their re-align procedures. When I have to align, I make sure I am able to use a hoop larger than my design so I can use the built in functions to move the design around inside the hoop. Before I get to the machine, I take my design into the digitizing module (I use Embird but all the digitizing programs will work), and add stitches to outline the end and beginning of my design. At the machine I thread water soluble thread in the needle. Then I stitch out the end and beginning that I just digitized. Its like previewing exactly where the design will stitch in relation to where the previous section stitched. Now is the time I use those arrow keys to fine tune the placement of the next stitchout. If my process is of interest, you will have to spend some time testing it, my procedure, before using it on a a real project. Oh, you dont have to use WST but its a whole lot easier to spritz away WST than unpick thread.
