Auto bed level Z offset inconsistent

[DBFIU]

I found this article


https://github.com/MarlinFirmware/Marlin/issues/1682

They were discussing that somewhere in marlin_main.cpp there was a line of code that offset the z axis by some amount, I dont know exactly why.

They said it was around line 1103 in the cpp.

Someone set Z_Raise_Before_Probing to zero in the cpp, to keep the head from moving up before it initiates a G29. Could this be the source of the z offset ghost?

People are trying a lot of different things. This Z offset problem is in all of the 'current' releases at GitHub. If we can get the BeckDac fork working on your machine you should be fine until things get cleaned up over at GitHub.
