Adjust Backlash
The RED Lens Control Motor offers next to zero backlash when properly installed. However, you may experience backlash with third-party motors, or certain lens and motor combinations.
The W.M.D. allows you to compensate for any backlash. Select an anti-backlash setting in the range of 0 to 3,000 encoder counts.

Adjust End Stop
The W.M.D. provides a buffer for the end stops. However, different lenses have varying requirements for this buffer. Some lenses require the motor to drive the lens right up to the end stop. Other lenses do not require the motor to drive the lens, and instead allow a large buffer to prevent high speed moves from overshooting into the end stop.
The W.M.D. allows you to compensate for the end stop buffer range. Select an end stop setting in the range of 0 to 3,000 encoder counts.
