Most plate solvers solve faster and more reliably if they know where they are supposed to be looking.
They find this out from the mount. They ask the mount where they are pointing, and start their search there.
Of course, your mount has no way of knowing where it is pointing for real----it just knows where it thinks it is pointing. It assumes that you set it up right, and therefore when it starts it is at position "HOME," which is for many mounts counterweight down pointing north. If you have in fact started it there, you are good to go. In case you may not have, however, it is good to send it to a known, bright star, center that star, and tell the mount: "You are definitely here!!!" At that point the mount knows for sure.
This is a "one-star alignment." Is it necessary? Maybe not. But it may make that first solve a lot easier, quicker, and more certain. After that, a reasonably set up mount should be able to find itself rather easily with successive plate solves confirming pointing.
