Configuration Error - Waiting for S.Axes

Hello,

I recently setup my mill with linxucnc and after a couple of reboots started getting a configuration error when trying to start up the AXIS interface. I can get to the LinuxCNC Configuration Selector (see image) but after making my choice it craps out. I'm not sure what causing it because I haven't modified anything since I initially set it up. What can I do? Thanks



Here is the terminal output after running linuxcnc &:

I think this one comes from having a line in your .ini file
like this :
NML_FILE = emc.nml

At least, I think having this line will cause that S.Axes error.

The line should be removed from the .ini file.

Jon

Ok let me try that.

Thanks for the reply but I don't have that line in my ini file.

This is what I have in my PRU-Driven-INCH.ini unless you're referring to some other ini file.

please post your hal config also

This is the hal file I found in the same directory as the ini file. Hope that's the right one.

Probably anything that causes emctask to bomb out will cause that error.

Jon

How do I figure out what's causing emctask to die?

it would be helpful to know which linuxcnc image you have uploaded and if you built from source
the command line switches

have you made any changes etc

Ah ok so the linuxcnc image I'm using is a custom one provided by Probotix which I got here www.probotix.com/wiki/index.php/PBX-BB

In regards to changes, no I haven't made any. After I finish writing a fresh image, I would boot it up and get to the AXIS interface window where I would manually step a couple of motors just to test. Then I would shut it down and later when I boot it up I get that error where I can't load the AXIS interface anymore. Haven't made any changes. This has happened twice with two different SD cards.
