X-Spot & X-Spot Xtreme Gobo Index

Hello
I´m a HES User in Austria.

So i just have a problem with my Gobo Index.
I don´t know if it is a really problem but it would save programming time if there is there something to solve.

We often use a custome Gobo so we have to project his Logo on a Wall in the right place.
so I use the index to rotate the gobo in the right direction.
Than i save that scene on HOG III.

If i recal that scene: Everything is OK. BUT the Index is not on the right pos.
I already checked the output DMX Value on the HOG III. That value is the same as programmed. I also tryed it with an Avolite Pearl 2000.
Same problem.

Can anybody explain me that problem.
best regards Daniel

    Hello Daniel,

    I can confirm Robert's statement based on programming experience with StudioSpot, Technobeam and XSpot Series like we have.
    Hysteresis of the steppermotor is one topic to regard.

    Please see the attached PDF-File which describes technically how steppermotors work and what there accurancy is/should be.

    Daniel,
    isn't your real question as following:

    1.) Why do I have to program this application with HES-fixture by using two cues in order to get accurat litho positioning?
    2.) Why doesn't one see this behaviour with Varilite or fixtures from other manufactures?
    Is this true?
