Out of curiosity what is the appropriate amount of belt tension to have? I’m wondering if after 2 years of operation I might want to tighten these belts a bit?

Check the underside of the belt for a damaged tooth. This can cause a skip as the router is moving to position to cut. If the damaged area of the belt is not in the location of your project you won’t see at the distortion in your project but it will not be in the place you want it to be.

Precisely what you are using it for.
nope, just the first time. With what it looks like you are doing, once you set the x-y zero it will remain the same with each piece of stock you place under it and up to the fence. Might have to check the “z” though…

I have more of a logic question:
If the machine is configured correctly ($100 and $101) and if the belts are not stretched and are tight, the hex would be accurate in width.
If the machine was configured correctly prior to belt stretch ($100 and $101) and if the belts are stretched and tight, the hex would be cut too large.
Based on the above; assuming the machine was configured correctly and assuming belts do not shrink, the belts are either stretched or they are not.
Therefore, the belts are either not tight or the machine is not configured correctly because the hex is neither accurate nor too large.
Is this logically correct?

There are 4 numbers in play:
- endmill diameter as specified in the file
- actual dimension which the endmill cuts — note that this can be affected by climb vs. conventional and tool deflection and so forth
- dimension of movement as specified in the file
- actual movement of the machine by the belts as they are tensioned
