The point about using only one part of the table is funny to me. A lot of hobbyists build 4x8 or larger machines, and then always set g54 to the same spot and use only that (because different work offsets on your gantry axis are often very hard to reach!). I guess with hobby machines it doesn't matter much if you use linear rails because you basically will never wear them out, but I found with my previous v wheel machine that this was a very real problem.
