But, you can also do it with manual jogs or G-code back and forth moves. I prefer manual, I do one move and then stare at the trace for a while before making an adjustment and trying again. The trapezoidal (velocity) shape of a move by jog or G-code is what the machine is supposed to do, anyway, so it makes more sense to tune with the actual profile the machine needs to make.
