Pan or Tilt Wiggle Uncontrollably

Symptoms/Issue

Upon start up or homing, pan or tilt constantly wiggle and cannot be controlled

Description/Explanation of Issue

Calibration was done incorrectly. Pan or tilt encoders will continually try to find zero resulting in the mirror wiggling uncontrolably.

Fix/Solution

  1. With the unit on its back and the mirror facing upward. Force pan and tilt encoder to time out by moving pan against the left stop. Left is determined by looking at the mirror from the rear of the unit.
