Zero First Layer Issues - FIXED

[Vergo]

I’d prefer to be able to save a good Z offset and use that each time with a new Eddy bed mesh rather than relying on the automated nozzle contact Z offset before each print that may or may not work properly.

As explained in this post linked below, that’s not possible because of the lack of a separate Z height reference point which isn’t measured with the tip of the nozzle:

Z-Offset is not saved

Probably the easier to understand (or longer) way of explaining the issue would go something like this: During print start calibration, the printer tries to figure out at what height the nozzle is currently in relation to the bed as it doesn’t have this information from the previous print or any other sensor. For X and Y, that’s done with the end stop switches that are at the end of the rails and those can be heard clicking during the X and Y calibration process. However, there’s no end stop sw…
