ASI6200 filter wheel doesn't repeat position.

Post by Xplode » Thu Feb 20, 2020 11:24 am

I found that the filter wheel doesn't repeat position so flats can be unusable.

Firstly i believe the FW driver should be set to unidirectional by standard, this will certainly help by eliminating rotation direction since stopping position has a big change when switching direction.
Secondly it seems the stop position varies when the filter wheel moves 1 position or 2 and more positions, a fix could be to force the filter wheel to move a full rotation.

I would love if the person making the driver could get in contact with me about this because i'd love to be able to help find a fix for this ASAP before more people gets the filter wheel and find the same problem.

I believe an easy fix could be to make the filter wheel always rotate a at least 360 degrees when switching filters, would it be possible to add this as an option in the driver to test it?

Dear Sir,
Sorry for the problem.
We analyzed the problem. It should be caused by some structural problems, so I am afraid it is difficult to solve now.
Thanks

So the solution will be a hardware fix?
Will the filter wheel need to be switched to a new version or just parts replaced?
