I was replacing my X carriage, ended up messing the whole thing.

My A and B belt idlers are fully loose and i had equal length belt, even down to the tooth count (from what i can see in the center cavity) but can't seem to figure out how to fix this seemingly minor tension difference, tightening the idlers doesn't help much, or maybe i am doing it wrong.
I don't want to order new belts and try again since i am worried about the quality of belts that i'd receive. These have worked well for me.
