Build Distortion map via menu
I saw that there is a bug if you build the distortion map via the menu option under Setup.
It shows on the screen to make sure that there is no obstacles on the table and to press OK when ready.
If you press OK then it does the distortion map probing, but that message stays on the screen after finishing the probing.
Pressing OK again(as the message says on the screen) causes it to redo the probing. One has to turn the encoder to remove the message.
This is on a DUE with the latest Dev branch.
Hope this makes sense.
