I've been having a problem getting the toothed belt installed properly in my nexdome. Interestingly the first belt shipped was 287 teeth and left a region larger than a tooth opened in the track with the gear track tight against the molding line of the dome (like the image in the instructions).
Now I have a belt with 288 teeth, which is what it is supposed to have. However I find I have overlap. I can have the belt hang off the bottom of the region for the tape, such that this is not sound for expectation of operation, and this belt is still too long and overlaps by about 1/4th a tooth.
I've asked Babek to provide panel sizes as review of all images of my dome does not reveal any user error. The dome does not seem to offer much of any play with what I've loosened so far and so I am not sure how I can expand the dome circumference further.
What would be a huge help is folks providing:
1) the length of their belt, perhaps the tooth count so we may know of yet another QC issue if present
2) the circumference of the molding line across the whole dome - preferably with millimeter precision, let's set our measuring tape above this line so we don't get involved with the gear train.
3) The easiest but probably most important: the length of each panel along the molding line (again, tape just above it)
I'm concerned one or more of the panels is "wrong" and unworkable. I bought my whole nexdome as one kit fwiw so while the dome if there's an issue present may have went unnoticed with a manual installation, the automated dome rotation is not in good or workable shape... I've made the same ask(s) to Babek so I can figure out what is wrong with this dome but it's been going slow.
Here's some measurements I took on mine with just a fiberglass measuring tape, I've got a track length of 132.5 inches due to it (sorry , tape was std, not metric). I stuck it ontop of the edge of the 3m extreme mounting tape.
