Re: Kisslicer and klipper

In my mind, this just doesn't make any sense.
How can Klipper know the area of an extrusion? Klipper does not "know" either the nozzle diameter or the layer height. KISS does not need to know the nozzle diameter; only the extrusion width. The required layer height is known by KISS and encoded into the G-code, but not in a way a printer's firmware can definitely determine (except, but maybe not even, for the first layer).
So for Klipper to set a "Maximum extrusion area" of 4.0 * nozzle_diameter^2 makes no sense to me.
Surely, a volumetic (or even linear) extrusion maximum would make much more sense?
Apparently in this instance, KISS is attempting to extrude 3.367mm^2. I would like to see the G-code where this is happening.
