FYI ... some of the machines you can switch the default position.
The factory default in my machine did not give me a 1/4" seam when using my 1/4" foot. I changed the default so that everytime I turn the machine on, it's in that position. So now the default is off centre. My other machine allows me to move the needle, but I cannot change the default, so if I change the needle position, I need to remember to put it in the right place when I turn it on ........... and yes, that gets forgotten at the worse times that it could and then I have to spend time with my froggy!
