Anyone who has assembled a NexDome has noticed tje inherent thumping, as the dome turns over the walls. In some cases the dome sections are NOT level with each other and this presents a more profound problem. This can cause the dome to stall or stick which can effect the dome rotation kit to jump the track or grind the gear.
Several have mentioned filling the space so I did. I used a modeling clay and filled the spaces between the dome sections. In a few areas I added material to level out a few of the uneven transitions.
It worked for exactly 2 days. First the added leveling material fell out as the dome ran over the wheels. Even after the clay fell out the dome was much quieter and ran smoother with the spaces being filled. The dome also didn't thump, stick or stall. The next time I was in the dome, all but a few, of the clay remaining in the spaces fell out. Other than cleaning up the clay the dome is no worse for wear.
I wanted to use a material that could be removed easily, in case of having to remove the dome for any number of reasons. I did not sand or otherwise rough up the area and I'm thinking that might be required.
If anyone has tackled this please post here.
I will keep reporting back as I try other materials or techniques.

I have indeed though about it, designed it (in Fusion 360), bought the wood to cut on my CNC router... not done yet as my dome is being replaced (long story and Nexdome is not the cause of the needed replacement).
So once that is done, I'll probably finish to cut the wood in segment and finish the flat wood ring to put between the dome and the wheel (I also did something similar to Alex with my 3mx3m short structure under the dome).
