I'm moving on to installing the dome rotation motor system. I was just looking carefully at the parts in preparation for its installation and I have a question. The motor shaft has a slot and a key as I would expect to see. The mounting hub for the gear does not have a slot. Instead, there is a set screw and the set screw is slightly bigger than the slot. This setup doesn't look right to me. Has anyone dealt with this and if so, what did you do? In case it's not clear, the gear will not fit on the shaft at all if the key is in the slot. The key must be removed and set aside.
I could just tighten down the screw in the slot to secure the gear on the motor shaft. To me, this seems like something that will fail, perhaps even over and over again. The easiest thing I can think of doing is to slightly grind down the tip of the set screw so that it will reach down into the slot. I think this will work but wanted to see if anyone came up with a better idea.
can you post some pictures ?
My magnet is dead center with my dome slit. My sensor is a 0º (due north, as I don't use the NexDome wall but built my own small structure for it). My park position is 321.5 degree (charging pads).
in my application (TheSkyX) I do enter these 2 values. The home azimuth is the most important as it defines the absolute position. The Park position is also important to make sure the battery can be charged. but can only be set after the home azimuth is set.
Once the home azimuth is known and set, hone the dome, then use the buton to move the dome back to the charging pad and use the displayed position in TSX to set my park position :

This is true for any dome controller (I've written over a dozen dome X2 plugin so I kind of know ;) and I also wrote my own firmware for my own dome controller).
And this is on my own dome controller , same principle (which is what I now use in my observatory with my NexDome dome, but as said, all are using the exact same way, set home azimuth, all move are in relation to that position) :
