Noticed when putting some LEDs on the top gantry that the belt in the pictures is a little too close by maybe a mm at most? The top tensioner is as far to one side as it can go (its a chaoticlabs one) and not sure what else to do. Any tips?
#Back right Z belt seems either too close to one side or hole is too small perhaps?

Yeah, something is definitely a bit misaligned. The belt should not be rubbing against the motor mounts where it's passing through (the motor mounts or A/B idlers), but there's only about a millimeter of clearance.
You should be able to tell if it's the z motor drive at the bottom (I guess how the pulley is attached to the shaft) or the idler up top by how the position of the belt looks with the gantry at the bottom or top.
I have the stock idler/tensioners, and I just slapped the parts in as per instructions and it worked out without having to align or adjust anything. I think the belt might be touching on one side in the B motor mount (when I wiggle the Z belt, it seems to have no clearance in one direction and a bit more than the other belts in the other), but it doesn't seem to be causing any issues so I left it alone. If it did deflect the belt like that I'd be a bit concerned.
