No, the M552 commands only work in standalone mode when not using the Pi. You'd have to manage the networking settings on the pi itself.

[jay_s_uk]

@Phaedrux m552 etc work if using the duetpimanager I think
Edit: they are usable. See here for info https://github.com/Duet3D/DuetSoftwareFramework/tree/v3.3-dev/src/DuetPiManagementPlugin

@jay_s_uk @Phaedrux

Thank you your replies and help.

I've disabled wifi with;
sudo apt update
sudo apt full-upgrade
sudo apt install rfkill
sudo rfkill block wifi

Probe sensor led is detecting every time, but Duet/Pi in DWC is still missing probe points?

Is this an SD card swap now, the feed rate of the probe is 120, so it's not going particularly fast?

[jay_s_uk]

@Dizzwold what do you mean its still missing probe points? does it come up with anything in DWC?

[chrishamm]

@Dizzwold Those network errors aren't pretty but they should not affect the code being run on the Pi/Duet. These messages can only show up if the connection between Duet and your device is interrupted, but it's hard to say why exactly they occur. It might be a driver issue, but that is hard to tell. Do the same error messages show up on another device, e.g. on a smartphone or tablet?

[Dizzwold]

@jay_s_uk

I have a 9 x9 bed compensation in place that should run once.

When I run the bed compensation My Z probe (a Tronxy TR Inductive glass sensor), detects every probe point which is shown by the led on top.
In DWC it doesn't detect all the points and runs the bed compensation 2 times and sometimes 3 times.
The probe is detecting, as if it didn't the bed would crash into the nozzle.
It's generally doing 2 runs of the bed compensation, and half way through the 2nd DWC throws up a network error.

So I've now disabled wifi on my Raspberry pi (running the Duet in SBC mode on a RPI 4B), and connected it to my networtk.

I send;
G28
G32
G29
It runs the bed compensation twice. Half way through the 2nd bed compensation it still throws up a network error, while connected to ethernet.

So the problem still persists on both wifi and ethernet.

Screen shot from my computer of DWC console;

2 Photos of monitor connected to my RPi;

I'm now going to try it again solely connected with a ethernet cable directly from my Pi to my computer.

[jay_s_uk]

@Dizzwold have you modified the bed file in any way or is the one you posted higher up still valid?

[Dizzwold]

@jay_s_uk

@Dizzwold the only thing that jumps out at me as being strange is you tell the firmware you have 4 screws, and probe 4 points but only have 2 motors. I would suggest that this may be causing you issues.
you should only set the 2 positions where the bed pivots on the z motor mounts

[Dizzwold]

@jay_s_uk

Okay, I'll change that.

I had problems connecting directly. I couldn't connect, so I've been a purchase one of these RJ45 testers and everything was fine. Checked the address again in the monitor connected to the RPi and the address completely changed, xxx.xxx.xxx.xxx/16, butwith a 404 page not found?

I'll change the bed.g now and run another test.

[Dizzwold]

@jay_s_uk

Thank you for pointing this out and correcting me on the correct path.

I remember reading about the leadscrew positions when I purchased the Duet over a year ago, and I think it was in the old guide (was it the RRF2 configure?), but when I used the configurer, when I finally got around to installing the Duet, things had changed and I didn't see anything regarding the leadscrew positions.
After I'd configured the duet I thought about this, so had a little search around. As I didn't find much to date on this, I just presumed things had moved on and this was no longer needed.
The guide does also state that for a bed like mine, to use the bed.g and give the positions of the screws to level it (using the manual bed levelling process, not the leadscrews).

Maybe I got confused?

Anyhow, I've changed the bed.g and config.g to suit the positions of my 2 leadscrews.

I'm now on ethernet, on my network, wifi disabled on the RPi and all my cables checkout okay.

Guess what. Only 1 scan with the bed compensation now and not 2 or 3, but still throwing up a network error?

I didn't have either the bed or nozzle heaters on for this, so going to d another PID for the nozzle before I try the bed compensation again.

At-least some progress. Thank you.

[jay_s_uk]

@Dizzwold do you have any more information on the probe you are using?

[Dizzwold]

@jay_s_uk

Not a great deal. I asked Tronxy and they either don't want to give much detail of they don't know. Here's there reply when I asked for details;
The TR leveler has no parameters.
All I know is it's 6-32v (won't work on 5v), NPN inductive glass sensor. I've connect it to the 24v power in on the Fysetc toolboard v1.0.
From my understanding it's similar to the PL-08N, except it will detect glass, and pretty good at doing so imo, although I've only used it with the ‘Lattice Glass’ that comes with it.
Blue cable = -v wired to toolboard io0 gnd
Black cable = signal wired to toolboard io0 in
Brown cable = +v wired to Vin power in on toolboard

[jay_s_uk]

@Dizzwold no more thoughts on that then.
have you tried running the 6HC in standalone mode if you're using ethernet?
avoiding the SBC route is typically my advice anyway

[Dizzwold]

@jay_s_uk

Hmm, no I've not tried it in stand alone.

To do so will I have to restart again with the configuration tool?

[jay_s_uk]

@Dizzwold you can download all your config files from the printer before you switch over, so download everything from the sys folder.
You'll need to add M552 S1 P0.0.0.0 somewhere in your config.g to turn on the ethernet interface.
https://docs.duet3d.com/en/User_manual/Overview/Getting_started_Duet_3_MB6HC#getting-started
Then use another SD card and put the downloaded files in a folder called sys in the root of the SD card
Also download DWC for the version you're running from here https://github.com/Duet3D/RepRapFirmware/releases and extract it to a folder called www in the root of the sd card.
Pop that in your machine and you should be good to go.

[Dizzwold]

@jay_s_uk

Lol, I've only got 64gb sd cards spare, not 32gb, what a dilemma to have.

I was just looking at the page you've linked to (getting started), I was also looking at setting up a fixed ip on the next page (getting connected).

Looks like I'll have to wait for nozama to deliver some 32gb cards tomorrow (i read somewhere you shouldn't go above that). Thinking about it I still have the original sd card that came with the unit.

[jay_s_uk]

@Dizzwold yes, fat32 only originally supported up to 32gb. you can force a 64gb to partition etc but its too much effort

[Dizzwold]

@jay_s_uk

Just tried it again after nozzle pid, heaters on G28, G32, G29;

It scanned twice again and through up the network error on the 5th row (9 across x 9 front to back), on the second scan.

[jay_s_uk]

@Dizzwold you must have a G29 somewhere in your files as that's what will do the 9x9
