Dynamic load balancing \ force cancelling gantry

The idea you made here is really great. The disadvantage of the approach is the higher energy costs for driving the machine. In Marlin 1.19 a feature called "linear advance" does an interesting thing for hotends:
"LIN_ADVANCE de-couples extrusion from the other axes to produce the correct pressure inside the nozzle, adapting to the printing speed. Once Linear Advance is properly tuned, bleeding edges and rough solid infill should be nearly eliminated. "

So wouldn't it be nice to use a gyro and implement a feature that calculates the movement of the sliders (considering their weight) to eliminate the shaking of the whole gantry? That would save costs for motors and additional hardware and lower the energy consumption of the machine.

If you read Ian's blog at [somei3deas.wordpress.com] you will see that he already knows a lot about pressure advance and he has optimised it for his printer.
