So I finally got around to deciding to try to measure my EAF backlash this evening, and I was expecting it to be somewhere between 60-120 steps.
I set the backlash to 0 in the ASI app and moved forward by 200 steps, and then I started going backwards in increments of 10, but the focus dial at the other side immediately moved.
So I went forward by 100 again, and put the step size to 9 and it immediately moved back.
I made the incremental smaller and smaller, and I could still see movement back and forwards every time I pressed the step buttons, right down to about 4 steps where I just couldn't see any movement because the increments were too small to see.
Did I just get really lucky and get a model with no discernible backlash?
Or is there something I'm missing?
