The only problem we seriously encountered in prototyping was not enough tension, and with the pneumatic tubing, we simply could not get that tension. It is also important to keep in mind that we were using and FP with a 6:1 reduction. Our conveyor system was very fast and without proper tension it lends itself to belt slipping. We had 2 inch rollers as well.

Our center rollers are powered, so when tension is applied to the top and bottom sets of idlers, they stay true. The only problem we encountered was too MUCH tension. But since we use barb fittings to hold it all together adjustments are very simple.
