z probe not referenced

axiom

@jay_s_uk

ah there is another message:
"G28
Error: Failed to enable endstops"

axiom

@jay_s_uk
the button "Home all"

jay_s_uk

@axiom then post the contents of your homeall.g file

axiom

@jay_s_uk
this is a standard feature that came with the dashboard... where can i find the content?

jay_s_uk

@axiom on the system tab on the left hand side

@axiom said in z probe not referenced:

G1 H1 Z705 F360 ; move Z up stopping at the endstop
G90 ; absolute positioning
G92 Z700 ; set Z position to axis maximum (you may want to adjust this)

you're trying to home using an endstop.
To home with a probe you need to move to the position you want to probe, usually the middle of the bed and then use G30
E.g.

G1 X150 Y150
G30

@jay_s_uk
I commented out lines 6 and 10 and added lines 11 and 12.
Now the message appears: "G28 Error: Probe already triggered at start of probinge move

here the new code:

@axiom said in z probe not referenced:

;G1 H2 Z5 F6000 ; lift Z relative to current position

this line is a good idea to have

@axiom said in z probe not referenced:

G92 Z700 ; set Z position to axis maximum (you may want to adjust this)

this line should be removed.

And what value does your probe show as having on the status screen?

axiom

@jay_s_uk now comes the message:

@axiom that shows that your probe is triggered already. what type of probe is it?

axiom

@jay_s_uk
a capacitive proximity sensor:

i got the same for my little ender printer and it works since 2 years

jay_s_uk

@axiom you may need to invert the signal
e.g. M558 P1 C"!zprobe.in"
but you should test it before trying to home with it

axiom

@jay_s_uk
now the z-axis moves down instead of up when homing...but it responds to my hand and stops

jay_s_uk

@axiom you need to invert the direction of your Z axis then. It should be negative movement going up and positive going down

axiom

@jay_s_uk And how do I do that?

jay_s_uk

@axiom Change the S value in each M569 for the Z drivers. If its 0 change it to 1 and vice versa

axiom

@jay_s_uk how do i know which ones are for the z-axis...since i connected two, i don't want them to work in opposite directions...that might break the motors

jay_s_uk

@axiom you've mapped the driver numbers in M584
