Kirk: That statement was already in my .hal file. But, I did comment out the 'motion.motion-inpos' line in the postgui.hal file and that did allow EMC to run. Thanks for the suggestion and I'll keep plugging away.

I looked at the module called motion: http://www.linuxcnc.org/docs/devel/html/man/man9/motion.9.html and noticed that there is an output pin called motion.motion-inpos, so if the motion module is loaded, it should show up. The motion page indicates that the module is loaded with: loadrt motmod [base_period_nsec=period] [servo_period_nsec=period] [traj_period_nsec=period] [key=SHMEM_KEY] [num_joints=[0-9]] This should be in one of your .hal files. One of my .hal files has this entered: # motion controller, get name and thread periods from ini file loadrt [EMCMOT]EMCMOT base_period_nsec=[EMCMOT]BASE_PERIOD servo_period_nsec=[EMCMOT]SERVO_PERIOD traj_period_nsec=[EMCMOT]TRAJ_PERIOD key=[EMCMOT]SHMEM_KEY This should already be in your file, so check for spelling and misplaced spaces, etc. You can also comment out the line calling for motion.motion-inpos by adding a # in front of the line. This will make EMC2 think that line is a comment, and will ignore it. This may get rid of the error and allow EMC2 to load, or just give you a different error. ---------- Kirk http://www.wallacecompany.com/machine_shop/ ---------------------------------------------------------------------------- -- _______________________________________________ Emc-users mailing list Emc-users@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/emc-users ------------------------------------------------------------------------------ _______________________________________________ Emc-users mailing list Emc-users@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/emc-users
