I'm trying to use a new filter wheel. It's the efw touptek model. The wheel is recognized properly; however, when I set a filter from the camera tab and try to take a picture, the wheel starts rotating, stops, but then it seems not to receive the signal that the filter has reached the position. It then enters a loop, and the camera never captures the image.
I'm using stable updated version of StellarmateX

Did you find a solution? I have the same problem but with windows.

Not yet. The issue lies with the ToupTek SDKs. I've also written to them, but they haven't updated the libraries yet. However, the wheel works fine for me with NINA and ASCOM drivers. Make sure you have installed the latest ASCOM drivers and also updated ASCOM on your computer. Clear skies, Corrado

Thank you for your answer. iI have the latest Ascom and also the latest driver from the touptek site, but looping forever.
