Well, I figured out that problem too and feel really silly now :oops:
Can anyone tell from the photos below if I attached the walking foot correctly? The first photo shows how it was attached, and the white lever from the foot was blocking the needle screw, so it didn't go down all the way...
The second and third are how it is now, but what is that white lever actually for (it sits on top of the black needle screw now)?
And thanks for all your help :-D

Needle screw resting on top of the white lever - is that right?
