Weld path replay error

nezzreth

I am trying to use the ArcLSto/ArcLRep command on my S4C+ controller for multipass welding. The tracking and welding work normally, but when the program gets to the ArcLRep instruction it says that no path has been recorded. I’ve tried using PthSaveToFile and PthReadFromFile; I have tried programming in RobotStudio then editing my code, as well as programming with the teachpendant. I tried using a recent system backup and the oldest system backup I have (as well as all of the ones in between). 

I think my problem might have something to do with Awc_2.mod because according to my Advanced Weld Control 4.0 Product Manual that is the module that controls path storage and adaptive tracking. I know my code is correct because it is modeled after an example straight out of the book. 

I am attaching my first post about this issue as well as the backup I am using. I have been stuck on this for 2 weeks. 

Help me Obi-Wan Kenobi, you're my only hope.

Also, here is a copy (not the exact one I am using) of the Advanced Weld Control Product Manual
