Where can we see the total milling time on the Emc2?

If you mean the actual time it took to run a program you can add a cycle timer to your pyvcp panel using the time component.

linuxcnc.org/docview/html/man/man9/time.9.html

If you mean a sum of the moves without any acceleration/deceleration or blending considerations then in the Axis menu look at properties.

Hello John,
I think it may be nice to know how long a milling takes before I begin.

That is not available unless you run the program through a sim and use the time component. Otherwise you will have to look at the program properties in Axis to see a total of feed and rapid moves less acceleration.

Click on File / Properties in Axis, and it gives an estimate that is usually pretty
accurate.

It can be close when the moves are long and the file is short. The splash screen when ran is within a second or two of the properties estimate. However the following G code file reports a run time of 1 second when you look at properties to run but takes 21 times longer to run on my sim as it never reaches the requested speed due to the maximum acceleration of the config and the short moves. This is a typical of a CAM generated 3-D g code with millions of tiny moves.
