mesh leveling help

Hello,

Is someone able to tell me how to set up bed compensation with the Z endstop switch that comes mounted on the E3d toolchanger. All i've been able to find is the G29 S0 code to use a probe. Please dumb your answers down, i'm new at his lol. I have the duet 2 with RR 3.2 firmware. Thanks for your help.

Regards

A noob with a tool changer? Jumping into the deep end to learn how to swim?

To use the switch as a probe you'd have to configure your M558 to use that switch as the probe.

Where is that switch wired to? You'll need to know the pin name.

; Z-Probe
M558 P5 C"^zprobe.in" H5 F120 T6000

P5 is for switch probe type
C is the pin name to watch for trigger. That's where your switch is wired to. In this example it's using the zprobe.in pin, but you're switch probably connected to something else.

Hi,

Thanks for the reply, Yep straight to the deep end for me, thank god for forums. It's in the "Z stop"

@Phaedrux

I have this

; Endstops
M574 X1 Y1 S3 ; Set X / Y endstop stall detection
M574 Z1 S1 P"zstop" ; Set Z endstop probe
M558 P7 X0 Y0 Z2 H3 F360 I0 T20000 ; Set Z probe type to switch, the axes for which it is used and the dive height + speeds
G31 P200 X0 Y0 Z0 ; Set Z probe trigger value, offset and trigger height
M557 X10:290 Y20:180 S40 ; Define mesh grid

on a G29 S0 call I'm getting the Error: z probe 0 not found.
The switch works fine when homing

I've tried adding
; Z-Probe
M558 P7 C"^Zstop" H5 F120 T6000

Same result: z probe 0 not found.

Maybe it's zstop**.in**?
Just guessing...

found out that v3+ firmware cannot have a Zstop work as a end stop and a probe.

So I tried this
; Endstops
M574 X1 S3 ; Set X endstop stall detection
M574 Y1 S3 ; Set Y endstop stall detection

M574 Z0 P"nil" ; No Z endstop @used by DC42 using G30 homing
M558 P8 C"zstop" H5 F120 T10000 A5 S0.01 ; Set Z probe type to switch, the axes for which it is used and the dive height + speeds @DC42
G31 Z0 ; Set Z probe trigger value, offset and trigger height
M557 X4:292 Y4:185 S16:15 ; Set Z probe: Define mesh grid

M574 C1 S3 ; Stall detect coupler at low end of its range

Still getting the "z probe 0 not found" error message

Can you confirm you are running RRF3 by sending and posting the output of M115.

Also remove

M574 Z0 P"nil" ; No Z endstop @used by DC42 using G30 homing

as its not required

If you run

M98 P"config.g"

Any errors should be shown.
Can you also post your full config file.

The config you have posted is for RRF2.
I suggest you look at these files https://github.com/Duet3D/RRF-machine-config-files/tree/master/E3D_Tool_Changer/dc42-wifi-centreZero-quadTitan

@jay_s_uk WOW that made a big difference, Thank you!

Nope. zstop is correct in this case. https://duet3d.dozuki.com/Wiki/RepRapFirmware_3_overview#Section_Pin_names
