[BUG] All surface offsets are changed after PROBE_CALIBRATE

[lettore]

When I do PROBE_CALIBRATE and restart I found that the difference between before and after is added at the z-offset of the bed surfaces. While this is maybe by design when you have a z-endstop and a probe to measure the bed mesh, it's not logical when you have a printer with only the probe sensor. Because with this behaviour it's impossible to fix the z-offset of the nozzle and the probe. I can't say how much time I spent before figuring out the problem. I also don't understand what trigger this action, so I can just simply disable it. At the moment I have to manually correct every surface offset manually.

The above is correct, there's a G28 after probing/leveling needed (or at least a G28 Z), before extruder stage 2 starts. When pre-level Z=0 and bed/gantry moves, 0 != 0

@lettore

I've successfully added a G28 Z, however, heating the extruder is already called and may delay the Z homing till it cools off but for now I guess it should work. If you're using the latest (with phased print_start) add this in your custom gcode (slicer print_start):

`_PRINT_START_PHASE_PROBING
; Insert custom gcode here

G28 Z
_PRINT_START_PHASE_EXTRUDER`

Please see the documentation for ADJUST_SURFACE_OFFSETS. When a Z probe or endstop offset change is detected at startup the console will contain a message instructing you to run this command, which can adjust the surface offsets or just accept the change without adjustments. The offsets are not adjusted automatically; you must run the command manually (or place it somewhere where it runs at startup).

@SarcasmRules Your comment doesn't appear to be related to this report. Perhaps you meant to reply to something else?

How you can say that the offsets are not adjusted automatically if is what I said is happening. I never run anything at restart but I get every surface offset changed after a PROBE_CALIBRATE, without running any other commands.
