Don't forget that the 4th axis board (G251) can be used to replace one of the other G251 boards in the G540 assembly if one goes bad for any reason (though these little boards are well protected electrically). The bad board can be sent back while you continue to have three working axes.
Hmmmmm, I kinda like the idea of an x & y axis table on my 22" throat scroll saw. CNC marquetry anyone? Cheaper to build and operate than a laser cutter.
