:worried: One of our robots was installed incorrectly. As a result, when the timing marks are checked they are off. The person who installed the unit is no longer with the company. What to do? Just re-align, but how to maintain accuracy when importing programs from RobotStudio? Wobj? ---

In Robot studio you are able to correct all targets… “copy and paste” by adapting the Wobj to the real robot program. “New wobj” and so on.. But in the s4c+ program “Program Maker” there are wizards that will help you to correct any errors if you’re program is a little bit off in a Wobj or TCP. Here is also a Mirror wizard if you are doing for exampel a program on one side of a car-body and will move it to the other side. but it is a hard work to get the perfect world i Robot Studio to adapt to the real world sometimes…and vice versa. I always feel that the robot need to be moved into position some millimiters to compensate re-orientations. But of course Abs-accuracy will help you on the way… to a perfect robot and program.
