Hi,
I am doing a sealing application. In my place we have developed the application, Since we had a difference in the production line. We have made a new base calibration, But we have difference of 5mm to 7mm difference. I have used the same tool and templates for calibration. I did 3point method.
What could be the cause for base difference???
base shifting accuracy?

when measuring base it is important to have a tool with correctly calibrated TCP. if there is an error then resulting base measurement will be off as well (for example tool was replaced or bent). also maybe the base was never measured correctly - if there was an error and all points are taught as if everything is ok, correctly measured base will no longer match the previous errors.

another thing to keep in mind is distance between points... you want this to be as large as possible.
if you teach base by using 3 points that are some 100mm from each other and then move robot 3m away, of course you are going to have large error.
