Im not sure whats going on here! I use the handwheel/rack for positioning the saddle. My leadscrew does not have a handle so its just for threading.
Visually the rack looks fine. I have not looked inside the saddle yet, I think there are a couple of gears. I assume one of the gears is slipping or worn. When it occurs it always seems a multiple of 2mm out, but the rack pitch is about double.
