They are tooth to tooth, but I think they are not tight enough into the "slot". The lower one seems be okay, but not the upper one. If I pull very hard, I see them slip (even if the bolt is tight). I think that adding something to squeeze them more will help prevent the slip. As for the best tensioner. It's just becose it's easier than unscrewing the stepper! :) I'll also use a spring like this ( [cdn1.bigcommerce.com] ) to keep the tension and still allow some play.
The spring is tight, but not "too tight". Before, I had to push the effector for like 5cm to get the rods in. Now I push only about 2cm, it's tight, but not too much. I over did it the first time I think. I'll add some silicone grease! I was thinking of it, but wasnt sure about it... thanks!
I found that the slots in the carrier where a little to wide for my belts and had issues with mine slipping to.
I modified them to reduce the gap and reprinted and they have been fine up till now.
Got my belts from china and I don't think all belts are the same quality.
