Displaying Real Time Extrusion Rate

[mopedwizard]

Has anyone programed the interface to display rear time extrusion rate in mm/s in the same we see printer head movement?

I push my setup pretty hard in a production environment and I would like to calibrate E steps, pressure advance, etc at the same extrusion rates in a given model. I know I can estimate these rates from the G-Code, but I would prefer to monitor the real time extrusion rate during the print.

@mopedwizard current DWC (3.5+). shows extrusion rate during prints. Its also part of the object model https://github.com/Duet3D/RepRapFirmware/wiki/Object-Model-Documentation#movecurrentmoveextrusionrate
