Z offset is in steps and calculated from the steps/mm defined in M8010. The difference between sensor read 0 and software z=0. It is exactly what you are temporarily setting when you press the z=0 button. Setting it in Gcode makes the setting static . You are absolutely correct that changing 8010 would be a nightmare, but this is not what was stated. I don't want a stepper without a spring because it is there to protect the screen. This is just basic printer calibration. Thank you and goodbye.
You are certainly right, I didn´t read attentive enough. (although I certainly did learn how to, already)
Skimming such big a text on an already solved problem I overlooked that you basically described how to unlock the "set-zero" function as is already known.
It´s up to you, to use the button or a fixed offset,. There are people out there who use a 3D-printed PETG taper bushing
instead of the insane rigid metal one and hence prefer the button.
There are also good reasons to level and determine "zero" below the sensor-zero. No pressure on the display while leveling in any case e.g.
Whereas the spring washer is not much protection with it´s 1-1,5mm when it really comes that a part falls of the built-plate.
But whatsoever, there´s a workaround, no matter with or without fixed offset.
Elegoo also provides a motor the same style as the newer printers are equipped and people have been happy with both ever since...
