I noticed a wobble after de-rigging yesterday. I tried to tighten the front cap bolt and is was stripped. It looks like the bolt only grabs a few threads in aluminum cap. Wonder if it is a corrosion issue. I did not think I had overtightened the bolt. Usually when you strip something you know it right away.
Same thing happened to mine but I noticed on the fuse the pocket for cap screw was not as deep as the other so engaged even less threads. Looks like someone stuffed up the -Z axis on the CNC
