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

@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

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

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.

Thank you to everyone for the help I'm getting decent prints now I'll probably hooking up the bltouch in a day or so hope u can handle that by my self but I'm not holding my breath. Lol
