Im curious as to how accurate your points are in Roboguide compared to real world? Even after calibration, how close do you get and do you still have to touch up your program when its taken to the real world?
Roboguide accuracy?

Probably depends on your configuration, If you have robot on rail or other external axes. I usually have 1 - max 2 mm error...

When I'm writing a new program, it's close enough to at least run without hitting the fixture.
I normally get it to within 90-95% finished in RoboGuide, then use an in house developed tip for our spray guns that uses a laser and zip ties to show the spray pattern to finish it up.We've gone from having to come in on saturdays to do new programming, to working during production's breaks.

Im using WeldPRo so im pretty anal about getting my points close and most are within 1-2mm but also get points that are way off like 5mm. THis is after calibrations.

Has the robot ever been remastered?
Have you checked the accuracy of your robot in the real world?
-
No the robot has not been remastered. You mean the accuracy between virtual and real world? If so that is what i was talking about 1-2mm but sometimes some points are 5mm off. If not the real world on its own never has any issues as our robots are new.

Keep in mind that if you are using any fixture or tooling there will be error in the machining. Unless you're willing to pay for +/- 1um tolerances during maching, keep expectaions realistic. I do all programming in RG with the understanding all critical points will be retaught. Stack up error in fixture building, work holding and tooling will keep it from being exact. As long as I have the path and logic correct (and won't wipe out a fixture), I can't ask for more. Just be realistic.
