Time to present my build. I ordered my first part in may '23 and started printing the parts. Used 0.12 layer height that gave a good finish. Had plenty of time anyway waiting for parts.
I would open this up some. That is going to trap a lot of heat being closed off like that. That looks a lot like a Vevor spindle. I run the same one and used the stock Makita mount with no issues at all. I would be worried with all of that extra you have. Its really not needed at all.
I’m going to put my money on you missed this step in the docs…
Pull those covers off and you shouldn’t have any more problems. If you still want to glue them down then hot glue is about the best option. But if you don’t pull the covers off even hot gluing them you will still have issues.
