Run From Selected Line working?

Every time I attempt to [Run From Selected Line], Axis always seems to start from the very beginning for me. Am I doing something wrong?

I am running a Ubuntu 10.4 system installed from EMC2 LiveCD image. Axis claims to be running EMC/Axis 2.4.6.

Hello,

Did you
Start running the part.
Then
Hit the Stop button at the top of the screen.
Then
Use your mouse to select the line to run from.
Then
Right click the line and select run from here?

- i always find that if im using boring bars in the rear turret, it wont restart from a selected line, as it thinks that it is going to overtravel, some sort of negative/positive addition error.

All:

Thanks for the suggestions. So far, on the real machine, it always starts from the beginning. I've tried both the stock EMC2 and the Run In Place EMC2.

On my lap-top, not connected to any machine, I have successfully managed to perform a run from selected line using the Sherline3Axis_inch configuration. It is not consistent though. Sometimes it starts from the beginning and other times it starts from the selected line.

I am really quite perplexed about this.

I think I understand what I did wrong here. I currently do not own enough tooling for my new mill so that I can preset the the tool offset for each tool. I had this exact same problem when I was first learning CNC on a Tormach CNC running Mach 3. Using Mach3, I could reset the Z at each tool change and or pause. Axis does not currently allow Jog/MDI at tool change. So, I reorganized my G code so that the G code for each tool is in its own separate file (as per recommended practice.) However, I wrapped each file in subroutine as follows:

When I load one of these files and attempt to run from the middle of the subroutine, EMC2 cheerfully picks up from the line runs down until it reaches the O1112 call at the end and the runs the entire block from start to finish via the subroutine call. It all makes sense, why couldn't I figure that out by myself?

I'll change my post processor to generate a file without subroutine wrapper for when I need to
perform a partial run.

Thanks for all the help, for what was basically a self-inflicted problem.
