Since i am not the only one with the “wish” I just copy-paste the topic from the AgOpenGPS International Telegram Group:
I think it would be great to have the AB Points never be changed by the AB Line Settings.
Think of the following:
Tractor goes to the field and got an implement with 3m width. He needs to move the AB Line by 1,5m to get away from the boundary.
2 month later he uses an implement with 9m. But the user doesn’t know who was on the field before with which implement. So how could he know, how much he needs to move the AB Line. From the original line - 4,5m - but from the line where it is now… don’t know
With the GPS systems i know (Fendt/Autofarm) the AB Line stays always the same and you only move the line for that moment. The offset is displayed on the screen. So it is easy to document and on every pass, everyone is at the same start point.
i changed the old AgOpenGPS version to save a “corrected by x cm” value to the AB Line. For our farm, this is the most practical principle. If other users experience the same problem, we could maybe change the way the AB Lines are saved.
i hope the thing i want to say is clear
