See 4th image down on the left. Sometimes this causes leaning - sometimes sudden shift exactly as shown in your photo. This is very common and easily fixed in a few minutes.
Most likely it's the pulley on the stepper motor.
Thanks, that's a very helpful resource to have! Didn't know it existed!
Turns out the bars were slightly not even and causing the belt to slip.
Consequently it looks like they've worn down a few of the notches so I'm going to have to get a new belt to replace it with.
