Thanks for this enlightenment.

It will be tough to depend on software. How about something like this:

In the CAM software will be a record of the feedrate.
With a linear encoder, we can extract the actual feedrate achieved.
Will having a slower feedrate than the one set indicate inadequate
torque?

Programing Einsteins on this list should find it a breeze to come up
with a program to compare the 2? Perhaps even with "set-able"
sensitivitly?

Thanks
