      @knuxvomica no they don´t.
      Current state: G28 homing failed , and nothing happens
      Before with a homez.g: The axis lifts 5mm, moves down then passes! the endstops and hits my frame when I don´t emergency stop...

      As you can see I am using the M564 command to test the axis movements in advance (which works fine) but obviously I don´t have any homing , i.e. no printing possible

      M564 H0 ;move without homing

      @Phaedrux said in Independent dual z axis with endstops - z homing not working:

      Please post your full config.g
      Homing Z should be as simple as a G1 H1 Z move to move the z axis such that the endstops are hit.

      You need G1 H1 Z-700 at the end of your homeall.g to home the Z axis. The same would be needed in homez.g

      Is individual homing for two Z-Motors possible?

      Yes, that's what I have on my Tronxy printer.

      It has dual independent Z motors, and I probe via G32 near the screws and it relevels the bed properly.

      sorry i just realized how the setup is one.

      are the switches NO or NC?

      i would try to wire them in parallel and use M558 P5

      they will need to be connected to the z probe port.

      but a construct would allow the printhead to move. this would not be beneficial for the print quality.

      Your bed.g file looks OK. Do you have a M671 command in config.g defining the positions of your leadscrews?

      @dc42 said in z axis random reverse homing:
      I don't understand...
      -wires checked ok
      -switched z motors to x and y connectors they work
      -plugged x motor in to z plug plus jumpers in the unused z connector it work ( switched between z1 and z2 connectors +jumpers ---all ok)
      -plugged x and y motors in to both z connectors ----just one work when i home Z (no sense!!)
      -plugged both z motors in to both z connectors homing z -----1 motor go fast 1 motor go slow (O.o)
      NOW:
      i have reduced M203 in config.g for Z to 900
      i have reduced in homez.g and in homeall.g F to 250 for z

      ALL WORKS

      thanks for the help if other strange things happen I will let you know
