Auto focus: Automatic focuser backlash calculation


#1

Hi there,

wouldn’t it be an idea to let SGPro do some AF-runs to calculate the ‘real’ backlash of the focuser?
I think most of the owners of stepper focusers are more or less guessing about the ‘right’ backlash including the right overshoot value.
Perhaps the AF routine could get a function to determine this automatically by doing some iterative AF runs. This should give a good idea about the focuser backlash.
