I am having consistent problems making IMG and MD backups on both Rj3i and R30iA controllers for various robot arms. I'm told these robots have been backed up before and I have some documentation from both manuals and 'employee written directions'.
The steps are very easy to follow, however, there is always some kind of problem I am unsure of how to navigate around.
For example, on one R30iA controller I have tried to make an MD backup, the teach pendant will indicate "Directory not found" when trying to make a directory to save the files (pressing 'Enter' when I've typed in the name of the directory I want to create). In similar cells which are meant to be replicas of the same system the controller will allow me to make a directory but say "Cannot save to this device". On some controllers the teach pendant does not acknowledge insertion of the USB stick at all.
I feel like there is something very simple I am missing here.
In another case, an Rj3i controller, the file directory reads "UD1:\BACKUP\*.*" which indicates to me that the controller is accessing a file that does not exist as the stick I inserted was blank.
Basically what I'm asking is does anyone have some concrete and detailed documentation of the robot IMG/MD backup procedures? I am fairly new to this area as you may gather
