Hmmmmm another long evening in the workshop trying to get a grip about things on the milling robot.
First a picture of the setup to make some things clear.
What I tried to do.
1) I have tried to change the base frame for the robot by going in under service --> view --> base frame and then choosing the robot and push "def...".
Then I can only choose the method "4 points xz". That is the only choice I can make (the user manual shows a number of different ways of defining the base fram but I only have one choice?

)
When I push the button for changing to the lower part of the window I can start to defining each of the 4 pointers but approching the fixed pointer 1 with the robot pointer from different directions.
When the 4 points are defined I jog the robot out to the fixed pointer 2 to define the +x elongiator and then I rais the fixed pointer 1 (which is a threaded axle which I can adjust the height of) so that it is around 200 mm higher then before and then approche it with the robot pointer and then define the +z elongiator. (is this the right way of doing the elongiators?

)
Do I need to define the fixed position of the reference point? (The set... choice in the lower right position of the window)
By the user manual I should now save the result but twhen I try to save it sais that the disk is writhe protected???
