z probe not referenced

axiom

I have a capacitive sensor. that should serve as the upper sensor. it's not my head that moves, it's the bed. From top (start point) to bottom. The sensor reacts (control lamp) and its reaction is also adjusted to the altitude. If I now want to reference the axes, x and y (endstops) work and the z-axis only moves a few mm. Then the message "the following axis ar not homed: z" comes up. What have I set wrong?

Here my code:

; Axis Limits
M208 X0 Y0 Z0 S1 ; set axis minimum
M208 X600 Y700Z1100 S0 ; set axis maxima

; end stops
M574 X1 S1 P"xstop" ; configure switch-type (e.g. microswitch) endstop for low end on X via pin xstop
M574 Y1 S1 P"ystop" ; configure switch-type (e.g. microswitch) endstop for low end on Y via pin ystop
;M574 Z2 S1 P"zstop" ; configure switch-type (e.g. microswitch) endstop for high end on Z via pin zstop
M574 Z2 S2 ; configure Z-probe endstop for high end on Z
; Z sample
M558 P1 C"zprobe.in" H5 F120 T6000 ; set Z probe type to unmodulated and the dive height + speeds
G31 P1000 X20 Y20 Z7 ; set Z probe trigger value, offset and trigger height
M557 X15:215 Y15:195 S20 ; define mesh grid

@axiom that looks fine although you don't need the M574 Z2 S2 line.
Post the contents of the files that give you that error

axiom

@jay_s_uk

ich habe die Zeile gelöscht, aber es ändert sich nichts

jay_s_uk

@axiom it won't until you fix your homing files (assuming thats where the error comes from).
Post the contents of the file thats causing the error. Is it homez? homeall?

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?

@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
