I know it is a pain to deal with this problem, but it is nice that your machine is designed to sense which hole is being used. I have to physically change the throat plate on my Bernina 440QE. I can't remember how many times I've started to do a zigzag, or move the needle far to the left or right when the small hole throat plate was on. Broken needle every time, but so far no other damage and haven't had to retime the machine.
