Running any duet product board completely without internet.
-
Is there any way possible to have these board work completely without the need of an internet access? Im continually having connectivity issues between all my printers where I have etiehr printers not being able to connect to the network, ir printers getting disconnected and ruining prints. I have 5 machines total running duet Wi-Fi’s or 3 boards. And they are very temperamental next to each other.
Is it possible by using a duet touch screen I can operate the machines without the need to connect to a network? Would make my life a lot easier running this print farm.
Thanks!

Change your M552 in config.g so that network is disabled
Or remove the whole network section.
Not sure if you'll get an error in if you try to set an SSID after network is disabled so you might need to remove the section
Then set up two macros to enable or disable it as required
That will make updates easier -

How are you printing that getting disconnected from your network ruins a print?
I have a wired Duet-2 board, and the Ethernet switch often gets turned off during a print and I've never had a print fail.Since you're having so many issues with lots of boards, and we KNOW these boards are reliable in the field, I thing we can do some more sleuthing to help yo figure out what's going on and get you better reliability.
If you can take the time to describe the symptoms when you disconnect from "the internet" and get a print failure.

Generally when I’m trying out long over night prints. What will happen, is the printer will just stop, mid print and cool down. When I look back at the log, I tall display, net work disconnection, and it will have no knowledge of a print even being ran. So there no way to continue. It’s a common issue when running over night prints for what ever reason.
This is particularly in my duet 3 printers.

@eddygara Are you printing over USB or over the networking connection or something?
Can you post "the log" that says you've had a network disconnection? That would seriously help debug this.
- How are you going about sending your GCODE to the printer?
- How are you starting your print?
- Are you running standalone or with a Single Board Computer attached.
Can you post one of your config.g files as well as the result of the M122 command?
ESPECIALLY right after a print has stopped, the M122 command output will be super helpful.To save yourself wasted prints and filament, you can:
- Remove the filament from your extruder.
- Add the command M302 to your GCODE file.
- Remove the temperature setpoints from your GCODE so everything is cold.
- Run the print.
If that works reliably, we'll have to start turning on the bed heater and let it run and then start the hot-end heater and let it and the hotend fan run.

This sounds like the board has crashed for some reason. Send M122 after that happens and post it here.
The network disconnection just means your connection from the browser to the Duet was interrupted when the board crashed, not that the network error is causing the problem.

I agree that i sounds like the printer itself crashed rather than it being a network issue. In the normal (well at least for me) flow of things, you use DWC to load the print file onto the Duet. As soon as that is done, the Duet runs completely independent of the rest of the world and will print until the current job is finished .... even if you shut down any network connection(s).
Network issues will normally result in an inability to interact with the printer through the web interface. Anything previously uploaded to the Duet will not be affected by loss of connectivity.
I don't know what kind of weird and bizarre scripting could be done but I suppose it is possible to induce a crash if the internet connection is down and a macro is running to specifically interact with the internet somehow. Even if that was to happen, there is no way the system would forget what it was doing.
My guess is that you have a power problem causing a hard reset in the middle of the print.
If your print job crashed/died, have you noticed that you have to re-home? That would be a clear indication of a crash and a very good indicator that you lost power.
If you are running with an SBC connected, make sure you have adequate power - Raspberries are known to have power issues when an aftermarket power supply is used. I don't know if a pi crash would cause a printer crash.
Lastly, you indicate that you have 5 machines running ..... unless they are tiny, you will likely exceed your available AC power unless you have multiple circuits running to your main panel. Note that in a normal residential situation, a single circuit running to your power panel can have a bunch of plugs and/or lights connected to it. You might have 5 printers plugged into 5 separate outlets and they could be all on the same circuit.
Determine the maximum power that any individual printer could be drawing - heated bed on, all stepper motors moving, hot ends on (could be multiples at once), power consumption of the controller board and any accessories ... etc etc ....
If there is conceivably a situation when all printers draw maximum power at the same time and you exceed the rating of the circuit, it is just a question of 'when' things will crash and not 'if' they will crash.
A normal circuit in North America is 15 amps at 120 volts and you should not exceed 80% of that load ... or 1440 watts (most small appliances top out at 1500 watts).
After you have figured out your worst case power consumption, think about what happens if your AC voltage at your location is low for some reason. What if you have power that is subject to frequent bumps or brown-outs. There are many things that go 'bump' in the night that could cause what you are seeing.If you can borrow a good quality (heavy emphasis on good) UPS, you might run a single printer off that power supply and see if you get fewer crashes on the protected printer.
Good luck, these issues can be difficult to track down!

Can you check your router, when all printers are on?
Maybe the boards all have the same MAC address (preset in config.g) or they are all fixed to the same static IP-address? -
@eddygara If you're experiencing issues with connectivity between your printers that are causing printing problems, you may be wondering if there's a way to operate your machines without needing an internet connection.
One potential solution to consider is using a Duet touch screen to operate your machines. This would allow you to control your printers directly through the touch screen, without needing to connect to a network. By using a touch screen, you can bypass any connectivity issues that you may be experiencing and operate your machines directly, which could potentially help to improve your overall printing experience.
