Is your feather touch on the primary knob and is it motorized?
If you are using motorized autofocus with the primary on EdgeHD then the autofocus settings should be about the same for f/2, f/7 and f/11 because the primary mirror is moving the same amount in each case. I have EdgeHD 11 and use a Rigel focusing system and it works well for me.
It's hard to know the settings you need because I don't know how much the focuser moves on each step with your system. But I would use a total of 9 steps and have the steps large enough that you see a good bowl shape in the focus curve.
You should also set things up so the focus curve happens as the knob turns counter clockwise.
And have 1/4 to 1/2 full turn of the knob as backlash compensation.
It may take a while to get all this set up - but after that it should just work.
