Question related to multiple Z endstop setup
-
I have a z_max endstop that is using a switch and a z_min endstop with a probe. Normally, I would use the z_max endstop for homing the printer. I am wondering if I first use the z_max endstop and home the printer, and then use G30 with the probe, what is the current z_axis referencing with? Is it the probe or the previous z_max endstop?

I have a Z "min" endstop switch that I use for homing which gets me to within 10 mm or so of Z = 0.
At that point I use G92 to set the actual position.
When printing or mesh probing I first use the Z probe for establishing the current Z = 0 position.

G30 is homing Z, just with probe, not endstop, so if you first home with Z max and then do G30, the last one, G30 result will be Z axis reference.

@Ray11 hey
Would you share your gcode?
I have 4 a axis and at the moment I'm not able to create my own g.code.
I'm still learning.

Home to zMin with your probe directly. Z max homing is only usefull for resume after failed print in your case.

Thanks i thing i got it figured out..

Here is an example of using a z min probe and z max endstop together.

The probe fidns the bed and the z max can be used for power failure resume. There is even a macro that will help measure the exact distance of the zmax endstop and save it.
