What do you mean by Festo cylinder? Do you mean helical type coupling? If so, best advice is replace with Oldham type couplings. Helical type couplings can wind up under some circumstances and cause binding. If the gantry is racking and is on slaved axis try swapping the wires from the drives over and see if it racks the other way. That should narrow down where to look. If it's always the same way, it can only be mechanical or a bad stepper or stepper wiring on that side.
