I am trying to get my rotator calibrated for my observatory. I am using in an Exploradome, so I had to modify the gear size in the driver. Once I did that I thought all was well. when I tell it to goto 180 degrees it rotates perfectly to exactly 180 degrees south. Same way for north where I park it. But when it tries to synch with scope the dome is 180 degrees off. Then I tried making it goto 90 degrees, instead it went to 270 degrees. So it seems like it thinks it’s in the Southern Hemisphere or something. I wonder if there is some parameter in the set up that I have over looked. Also the dome rotates counterclockwise to find home rather than clockwise which the documentation says is how it is supposed to work. This is with the arduino version of the Nexdome driver. My magnet is at azimuth 1 degree, and north at 6 degree.

Ok, let us know how it goes.
North IS zero degree. So how far from north is the sensor on the fixed structure ? That will be your home position.
Getting the magnet azimuth correct is key top having proper goto. Direction is also key. so if your motor turns the wrong way, swap the A/B pair of the stepper motor
I followed procedure in GitHub documentation for nexdome Arduino ascom driver. So magnet is at 1 degree, north is at 6 degrees, so home azimuth should be 1-6, or 360-5, or 355. Instead I misread it and entered 1. So I will try 355 next and see what happens. Since my magnet is not exactly at north, I am assuming I should do a goto to 0 degrees and see how close it is to true north, then change home azimuth until it is exactly north. I hope this solves it! If not I noticed there is information on how to rewire stepper motor so that it turns the right direction. I will try that next. I am using the old nexdome Arduino driver. Thanks for your help!
What Azimuth did you set for the home sensor ?
All internal position in the controller are in relation to the home sensor position.
Also as your direction seems reverted that might also be the issue, try changing it.
I assume you're using the new controller (Lunatico Beaver).
