When printing it is very helpful to know

How much material is left on the spool,
at what layer will the material run out,
what time is it when it runs out.

Which printers will be beneficial to this feature?

All

Describe the solution you'd like

I request that a display of the calculated cumulative material used in a given slicing operation, is presented along with the now available Height, Time-to-layer, and Layer Number in the Slicer 3D view.

When a new spool is loaded, a counter could be (re)set to show/know the size of a new spool, and keep a log (-file) on how much, and what, material has been used, either/or calculated or measured.

A real time clock could also be used to show what time of day the layers take place.

If the hardware has a filament feed/speed sensor, the speed of the sensor and and material used can be measured , logged and presented.

The work of jrowny https://github.com/jrowny/cc_sfs gives a simple solution to filament speed sensing for one model of 3D FDM printer.

Preventing clogs and air-prints is better than watching a video of a messed up print.

Describe alternatives you've considered

Alternatives? Hard guessing, head scratching?

Additional context

As the slicer calculates material used, it could also well add a cumulative number for the layers selected.
