error upgrading

PeterA

Hi, I generated a new one then Formatted it a bit as you can see. Its like the Duet is not registering that the Z piezo has triggered even though it has. I would think that I've got something wrong with identifying it or something in the config.g???
Any way here's my homeall.g
I was getting errors so i had to replace all the S(x) switches with an H(x).

@PeterA said in error upgrading:

M574 Z1 S1 P"!zstop" ; configure active-high endstop for low end on Z via pin !Zstop

you generated a config for a z endstop not a z probe.

there is no G30 in you homing script.

PeterA

@Veti
OK so do i change that to
M574 Z1 S1 P"!zprob" ; configure active-high endstop for low end on Z via pin !
Not sure if that is even a command??

Veti

@PeterA said in error upgrading:

M574 Z1 S2 ; configure Z-probe endstop for low end on Z

but the homing script is more important.

generate a new one in the configurator,
load the json and change the z endstop to probe

PeterA

OK thanks Ill go give it a try

@Veti said in error upgrading:

M574 Z1 S2 ; configure Z-probe endstop for low end on Z

His config.g file says it's for v3.

From the v3 documentation:

The S2 option of M574 is intended for use only when axes other than Z are using the Z probe for homing. ... When using the Z probe to home Z, M574 Z0 should be used.

Veti

it works either way.

M574 Z1 S2
is what the configurator creates for z probe on version 3.

but as i said more important is the homing script.

PeterA

OK so done all that. Now when homing all z Just lifts up then says its homed. I can see the piezo is not triggering. Below are the changes I made in bold.

config.g
; ##### Endstops ######
;======================
M574 X1 S1 P"!xstop" ; configure active-high endstop for low end on X via pin !xstop
M574 Y1 S1 P"!ystop" ; configure active-high endstop for low end on Y via pin !ystop

So I'm not sure???

PeterA

When using the configurator the z option for piezo remains greyed out. So i used the old settings???

Son of a gun. That's confusing.

Turns out, at least on 3.2 that M574 Z0 or M574 Z1 S2 or M574 Z2 S2 works.

It even worked with no M574 referencing Z at all.

Thanks.

Which makes complete sense since G30 only cares about M558 and G31. M574 is for endstops.

In your 2.05 config for the piezo you have it inverted and P8 probe type. To do the same in 3.2 you'd add a ! to the pin name. Try this.

M558 P8 C"^!zprobe.in" H5 F450 T5000 R1

That would match your previous settings.

You should also check your config.g syntax by sending M98 P"config.g" This will report any errors that may get lost during startup.

Sorry guys had an internet issue. Bust testing now

I agree but when homing with z probe the documentation states that for v2 M574 Z1 S2 is needed and for v3 M574 Z0 is needed.

So something is out of sync - the firmware is right and the docs wrong or vice versa.

Curious. Thanks.

@Phaedrux
Thanks. Sorry I've been making so many changes following some of the other guys. Just getting seriously lost.
I tried your suggestion and now i at least get an error:
When homing the Z it says :

1/21/2021, 6:44:30 PM Error: Z probe already triggered at start of probing move
Error: Homing failed

I'm really getting a bit lost. Can you see any mistakes ?

Also the M98 P"config.g" reports this;
1/21/2021, 6:52:01 PM M98 P"config.g"
HTTP is enabled on port 80
FTP is disabled
TELNET is disabled

So I've changed my config.g to the following:

; ##### Endstops ######
;======================
M574 X1 S1 P"!xstop" ; configure active-high endstop for low end on X via pin !xstop
M574 Y1 S1 P"!ystop" ; configure active-high endstop for low end on Y via pin !ystop
M558 P8 C"^zprobe.in" H5 F450 T5000 R1 ; set Z probe type to switch and the dive height + speeds

; ##### Z-Probe Precision Piezo #####
; ==================================
G31 P500 X0 Y0 Z2.5 ; set Z probe trigger value, offset and trigger height
M557 X10:328 Y10:210 S20 ; define mesh grid
; M557 X10:328 Y10:210 P5 ; Define mesh grid

and my homeall.g looks like this

as phaedrux says change to
M558 P8 C"^!zprobe.in" H5 F450 T5000 R1 ; set Z probe type to switch and the dive height + speeds

when you issue M119 you can see that the probe is already triggerd. the ! inverts the signal

Where does it say that?

In the notes for M574 in the wiki it has this:

The S2 option of M574 is intended for use only when axes other than Z are using the Z probe for homing. The only printers known that do this using Duet electronics are the RepRapPro Ormerod, Huxley Duo, and Mendel Tricolour machines. When using the Z probe to home Z, M574 Z0 should be used.

And even that has an asterix, because you can define an endstop (for zmax for instance) and use either the probe or the endstop depending on what you call to home at the time. G1 H1 or G30.
