As for GT vs HTD belts - the biggest thing to keep in mind is availability of particular belt lengths. Sourcing GT2 and GT3 belts can be difficult, but it is extremely easy to get HTD belting. I have heard that the HTD's deeper tooth profile is supposed to be better for reversing loads / ratcheting prevention as well, but I have no data to back this up.



If belts are properly aligned and tensioned, this just shouldn't happen. When the belts are on the pulley, they aren't moving relative to each other at all. I've never run into significant problems with a setup like this.
Does 2791 add any additional spacing between centers in their drivetrains?
