machine stops in the middle of an NC program

I'm running version 2.3.1.

My problom is that AXIS stops (not pause) my 51000 lines NC program in the middle (actually at line 1014). When I restart the NC program, the CNC machine doesn't move. But the CNC machine is responsive to homing and jog buttons. I quit AXIS and start again, it stops the NC program in the middle and the same things happen.

It seems like the Gcode interpreter dies while processing an NC program, but I don't find any error message in system log.

To recreate the problem (even without connecting to a CNC machine):
1. create a configuration where X = 0 to 600, Y = 0 to 400, Z = -130 to 0
2. home all axes
3. offset X, Y and Z using the jog button (say: X = 100, Y = 50, Z = -70)
4. click "Touch off", enter the value 0 and coordinate system is "P1 G54".
5. load the attached NC program
6. run the NC program.
7. somewhere down the lines you will see the NC program is stop!!!

Attached is a copy of the NC program in case someone would like to try.

Can anyone tell me if i did anything wrong or it is a problem of EMC2.

Thank you very much for your assistance.

Sorry, the forum doesn't allow me to upload the NC program.:S :S :S

It depends how large it is. Maybe you can use pastebin.ca or a similar site to upload it.

PS: if that doesn't work, you can email it to me

A copy of the NC program is available at :

Thank you very much.

I have found out that AXIS stops the NC program in the middle if it is started from "Execute next line" followed by "Resume execution".

Attached is a copy of the log file, I hope that it contains useful information for you guys to find out the cause of the problem.

Thank you very much.

Having read through the source code, it seems the interpreter ignored the remaining lines after buffer full, I need to add some debugging messages to the program to trace it.

The function" emcTaskPlan" is too long and too many "switch"es, somebody needs to tidy it up.
