Probing and home position

[Martin Zabojnik]

summary of ideas

home position is not always exactly the same. due to inaccuracies switch.

after probing is not good to do again homeningZ . it make small error of position

position of PCB must be in positive coordinates . because the firmware not understand 

negative position .

it is ok ?

Martin explains that he does not see the need of precise Z homing (Zmax position) since all the Z scale can be levelled based on precise Z probing. What I can observe now when testing the GUI from Kobus is that obviously it is not intended so, as there are 2 homings - one before and one after probing. Details would have to be explained by Kobus, including how demanding it would be to implement the principle in the probing software.
Martin brings as example the cncgcode controler host of Patrick Knoebel.
