Well, they're not strictly speaking *incompatible*. CSC just mentions a couple of points that RHB omits. In both publications a TL13 fab is only capable of simple biomechanical prints, with full organisms being grown in bioreaction chambers rather than fabricated. It can fabricate an organ but not a person. The TL17 version can, though. You need a chamber double the volume of the fabricated object in both.
I'd just put it down to RHB being all about slots. CSC doesn't use Robot Slots as a unit, so expressing chamber size in chamber litres is better there. CSC does provide a conversion. As far as I can see, the CSC entry is the full description, with RHB being a subset.
RHB is fine if what you are printing are other robots, or small items. If you need industrial size or external fabricators, CSC is better framed.
