Maximum flow rate field

Hi,
could you please add an option to limit the maximum extrusion volume per second (e.g. in mm^3/s)?
This would help to better control material flow and avoid overloading the extruder/hotend.
Thank you!

Hello, I was talking about this @bkerler recently.

The problem is, max flow rate is actually not an overly meaningful number, because for the same material, it practically differs from printer to printer - things like nozzle type, heating power, printing temperature all affect it.

Melt Flow Rate or Melt Volume Rate might possibly be an alternative candidate, but we'll need to link into it more.

Most vendors have MFI or MFR in their specs, but this needs to be linked to the temperature (and pressure) as well (most vendors seem to give this information as well but not all).
