Hey guys, hopefully this will be a quick and easy one. I'm replacing the X axis nut on my FP-1. I just got the new part from Singer and it's not clear to me what the purpose of the small groove going half the length of the nut is for. It seems like something that should interface with a key, but removing the old nut, no key or alignment dog is there. It seems strange that they'd take the time to cut that groove for no reason. Am I missing something?
Anyhow, just wondering what, if any, purpose that groove has? Thanks very much, as always for your help!
