I'm not an expert in energy consumption modeling; still maybe I can give you a hint or two...

It is difficult to answer this question without having a particular example machine layout in mind. Cartesian machines will differ from delta machines. In any case, you have the energy needed for physical movements (in a Cartesian machine: XYZ and extruder axes). This depends of course on motors, friction, and target movement. The latter depends on the gcode you are using for the specific part.

Then, you have all heating elements (nozzle heater block and heated bed if present). Their target temperature at any point in time depends also on the gcode file.

Then, you have all the electronics components: Processor, main and auxiliary boards, motor drivers, display, power supply. They all consume energy depending on what you do with them.

To get even a vague idea of how all these components act together with respect to electrical energy consumption, you will need to analyze how they react to different gcodes. As a starting point I would suggest to do this using a particular example for which the technical specifications of all components are freely available (Prusa machines would be an option since they are open source hard- and software).

Hope this helps a little.
