I experienced this issue over the weekend when we had an excessive load on the end of arm tool. The crazy thing is that the Nachi robot ignored three positions and moved past them all destroying all of our tooling. Robot has been running for 2 years with no issue but has occasionally skipped lines in the robot program. Not sure if anyone has experienced this but this is definitely crazy.
