Belt tensioners - Loose pulleys to apply?

[fuchs 0]

I wonder if one should loose the pulleys on the axis when applying belt tensioners of the "clamps on one belt" style?

I mean, after all the tensioner will "shorten" or tension approx. one half of the belt, but the belt will still be in the tooths of the pulley, so it will get more tension on that side, while the other side wont get any tension (i think).

When putting my belt tensioners on, I didn't loosen the pulleys and now I am worried, that over time the belt will get stretched unevenly.

Comments?

I think any time you adjust the tension or the alignment of the axis you need to loosen the pulleys, other wise your print will mess up. I wouldn't worry, just loosen the pulleys now, adjust tension and axis and move on. IMHO, I don't rally like the adjusters that sit on the belts, prefer the ones on the block.
