@Vince.Fab’s ProvenCut has done some of that with the machines that he has access too - including a “1500 W” Shapeoko HDM. Unfortunately, even though he likely has a pre-lock down version of the VFD and hence access to actual cutting power and torque, he apparently uses NYCCNC’s K Factors (shown in one of tabs of the SFPF Calculator) for his power estimates. Maybe if he had more subscribers (<$50/year) he would continue this worthwhile endeavor!
Others could too especially if they had access the data readily available from the VFD!
