I’d like my machine to be as rigid as possible, and I read in the aluminum guide that 3 inches or less of Z travel is ideal for this. However, if I plug something like 2 inches into the conduit cut calculator for Z travel, it says that the leg pipe length should be 1.5 inches. Since the foot part itself is taller than 1.5 inches, how is this possible? Will there be no exposed pipe between the foot and the lock corner?
Two ways. You can screw the corner bottoms directly into something and use a table that has an adjustable surface, I call it a “drop table”. Or you can just cut the legs to fit the two pieces, 2 3/8" long.
