I recently set up a program and everything was fine. I am using tool frame 1 and user frame 0. All points were good. I came back this weekend and all points are now off, like they have been shifted from the original positions. I haven't made any changes to either frame and unless somebody else has done that without realizing it I'm not sure how this could have happened. Any ideas from anybody would be greatly appreciated. I really don't want to have to touch up all the points again.
Robot points are off

Most common issue is that something has physically moved. Check for loose bolts on robot base, end effector, and fixture. Check if the end effector is bent. Do you have everything anchored properly to the floor?
Also, this is why you should teach a user frame and not use UF 0.
People always claim the robot somehow changed position, but in my experience that has never proven to be true and the issue always ended up being mechanical.

Glad you found the issue. Now just have to make sure someone isn't accidentally changing the program.
As for your user frame, I would have taught a single frame for the table itself. If the table ever gets bumped out of position you will have to reteach everything.

If your table is fine, you can still teach a frame to it, and then convert your program to your frame. The frame convert utility under utilities will let you do this.

I seem to have this issue as well my robot being a new Fanuc Arc Mate 120iD/12L i set up 600+ line job and all the points are off about the same amount in various XYZ directions and but my TCP is point on. Very frustrated at the moment. Luckily Lincoln Electric is coming in to morrow so when i figure out what is happening ill be sure to drop you a line here to help you out.

There's some new utility that pops up when the controller is turned to setup utools and other stuff. This utility will erase the current utools values.
