As DC42 mentions here:
The resulting print time of a simulation is stored in the gcode-footer. My experience is that this estimation is very accurate, much more so than estimations from the slicer or DWC during print (based on filamet use, file progress and layer time).
Would it be possible to read this information from the gcode during print and display it alongside of the other print time estimations?
I would also be nice to see the print time estimation from simulation in the gcode file browser.
