hey so i finally got my belts and bearings in and ive been working on my own hbot, and what ive discovered is that, in an "hbot" configuration the belts actually create a torque across the beam thats being moved and therefore twist it out of alignment, in the corexy this is fixed because the belt moves the same way on both sides of the beam. also the belt stretches less because there are two shorter lengths, which allows for higher belt tension. btw im using gt2 belts. also I have discovered that the corexy allows you to correct the alignment of the bar by shifting the belt, it is much much better than the hbot configuration if your crossbeam is not 100% solid, which mine is not because its so light weight, only a half extrusion 20x10mm.
