This is only true in a very limited situation: if you expect the table to be planar (what if it's a hemisphere?), and you avoid arcs completely. In the general case of compensating for a non-square non-orthogonal machine (whose geometry changes randomly from one day to the next?) and running fully-featured gcode, it's inadequate, and a full kins solution that runs at every servo cycle is more like the answer, but you still have such a rabbit-hole. ------------------------------------------------------------------------------ Sponsored by Intel(R) XDK Develop, test and display web and hybrid apps with a single code base.
