Think back to your math class - functions were approximated what by short segments. I see you get the idea for the XY path but you missed the accel part. You can approximate the acceleration path in the same way.
Remember a G1 has a speed function. If you can figure out how fast something is supposed to be traveling a position X, then you can can figure the speed at X1. The commanded speed change between these two points will be acceleration your acceleration G01 X1.0 Y1.0 F10 G01 X2.0 Y1.0 F20 between the above lines will be the change of speed (aka accerlation) in the X direction G01 X1.0 Y2.0 F30 Now you have an acceleration component in two direction (one involving a reversal of direction) you should be able to take it from here. Be careful, you may begin to visualize functions if you do this too much. But then again, isn't that art?
