That looks like you have a lot of backlash. For that amount of rotation of the screw I would be expecting a much larger count in the plugin, it is only moving 1 or 2 counts., so it would seem the screw is rotating but the axis is not moving and thus the scale if not registering movement.
I presume you have the correct value in Motor Tuning in Mach for STEPS PER UNIT?
If it is indeed backlash you will have to eliminate it as you will not get things tuned very well, that is the downside of linear scales rather than encoders, any backlash and it is extremely hard to get a decent tune.
