I have been using the Pyxis rotator for a couple of years now and it has always worked very well for me. I use both the wire loom similar to what DesertSky pointed out. I also use lots of Velcro. The way I have it wired I haven’t had any issues with cabling. Below are a few pictures. What has happen to me in the past, and I do now check every time before I power up the rotator, I ensure all of the connections in the imaging train are tight. I found due to the rotator those M42 threads seem to work loose every once in a while.
Also, in the Target Settings of SGP I always using the Rotate Camera to and keep the +/-180 Degrees. This way I only need to take one set of flats. I let either Deep Sky Stacker or PixInsight do the rotating of the images when doing the processing work for stacking
In my images is showing the rotator in the “0” position. when I power on the rotator it rotates counter clockwise 180 degrees, finds home then returns back to the “0” position.
Hope this helps.
