Encoder Finessing

If you are running into position accuracy issues the most likely culprit is the dancer wheel encoder.

• Check the drive edge.

  • Unevenness where the encoder runs can cause poor positioning results

• Confirm the encoder wheel is parallel with the top of the revolve surface. If it is out of alignment, shim the revolver base.

• Add Encoder Match marks

  • Mark the top of the revolve and the revolve surround with matching tape marks. These will be your main reference marks.

  • Mark the top of the encoder wheel and a matching mark on the top of the turntable. These will be your encoder reference marks.

• Run the revolver manually from the face of the Stagehand 360 degrees forward, lining up your revolve match marks.

• Run the revolver back 360 degrees, lining up your main reference marks once again.

  • Once the revolve match marks are lined up look at the encoder reference marks.

• If the encoder marks are not aligned, add some additional tension to the encoder spring, realign your encoder marks and repeat the testing process.

• Repeat these steps until the encoder reference marks are aligned.

  • Once aligned (or close), redo the position scaling
