Points to note

• [ ] Set "Backlash compensation method" to "overshoot" (Important: Can only be changed if EAF is disconnected!)
• [ ] Set Threshold for R2 value to around 0,8-0.9
• [ ] Find backlash (video below) If necessary play with values for "Backlash"
• [ ] "Curve fitting strategy" ("Hyperbolic" vs. "Parabolic")
• [ ] Using narrowband filter like LeNhance? - Increase exposure time.
• [ ] "Autofocus step size" (potentially increase a little)
