Hello and thanks for the reply.. Yes, other software sees both the camera and filter wheel fine. SkyX sees the camera fine. I'm familiar with 200 and 215. When the system boots, you can see the filter wheel moving (briefly) left and right, so there is a connection. Again, tried the obvious of new cables, etc..
I have it working again on a totally new system build and will try to see what may be knocking it out.. Bullseye Update, Updates to SkyX, etc.. Will do my best. I'm going to erase the ZWO files on the failing system and reload the beta code again.. I will keep updating.. Just SOO insanely crazy that a working system with the beta code, just stopped working.. At that point in time, I had not done any updates to the application code on the system or the base OS itself..
I do appreciate your working with me on this. For the record, on the failing system, a Starlight Xpress EFW connected to a ZWO camera (1600) works fine..
