Firmware wishlist and priorities for Duet WiFi and Duet Ethernet

It would be nice if the wifi would create it's own network if one isn't detected when booted up. And have the name of the network be the name of the machine.
Something like that could be used for initial configuration as well much like other wifi devices. It creates its own access point which you connect to, you enter the wifi network information and reboot. Then continue with configuration afterwards. No need to connect to a PC first via usb or edit files on an SD card.
And having it fall back to the same access point mode if the configured network is no longer present would be helpful.
-
Some home automation devices use the same logic, some of them even have a dedicated button which puts them into ap mode, where you can configure the network.
-
It's mostly a security issue. If for some reason the initial connection fails and the Duet goes into AP mode, do you really want anybody to be able to access your Duet?
A possible mitigation would be to use a password based on the chip unique ID and to put that password on a sticker attached to the Duet. It could still be inconvenient if your Duet was buried below the bed of a delta printer so you couldn't see the sticker.
-
You could use a part of the serial, which could exist on a sticker, and coud be queried threw M122, so it's accessable directly and could be red threw usb in case the panel is buried.
A problem would still exist, if there is a power outage, the duet would boot up much quicker than a WIFI router, so if this functionality is automatic, then it would go to AP mode...
As a workarould for the duet 3, you could add a button on the panel to put it into AP mode
-
@denke why? Because you need to set the network one time. Then you can edit it when you want. If there is a security bug someones van take over your machine and do some crazy stuff
I think that something like that puts a lot of effort tot maintain in the firmware. With all the security issues Everyday we have.
Just my 2 cents
-
@mickey30m I don't need this functionality, I just think it would be quite easy to implement, would add value to the product, and would solve all the threads complaining about "cannot setup wifi" just because prontenface switched both essid and psk to uppercase.
As to the security side, almost all wifi routers supplied by ISPs today have a sticker on the side containing the wifi and admin password, and it's not much of a security threat, I suggested the exact same functionality
-
it is very handy, but i dont know if it is good for the users that are not that technic.
on the other hand, when someone take over you're router the also can control the printer. so why not
-
Another way of doing it would be have it on by default. And gave it as a parameter to turn it on or off during set up. Also could put in a delay to have it turn on if network not detected after x number of seconds/minute. And it could have a parameter to check for network every x minuts.
Dose the duet store multiple networks and passwords? I will be taking my printer back and forth between home and school and am lazy enough not to want to set the wifi up each time.

yes it does, multiple SSIDs and passwords can be configured, the Duet connects to the strongest one.

Cool is there any special way of doing it or do.i just send a m command for each network and pass?
-
Is it possible if we did the auto network to have a popup to set a password the first time you connect to it?

Yes, that would be possible, if we made DWC recognise that situation.

Would it be possible to add support for filament width sensors? I know people in most countries have access to cheap filament with tight tolerances but I can get a much cheaper filament that is not as consistent in diameter but is good enough in the other aspects. Another way of seeing it would be to automate the per roll flow calibration.

Can the switching mosfets on PS-ON be uprated to take 24V directly? 24V is more typically used in industrial saftey interlock systems and relays.
Last time I chevked they were only suitable for about 5V - which is the ATX ps on signal.
-
On the schematic I see that the PS_ON switch is PMV40UN2 (https://www.nexperia.com/products/mosfets/n-channel-mosfets-25-v-30-v/PMV40UN2.html). This is a 30V MOSFET. Even more, it is capable of quite some current (4.4A based on the datasheet) as it has a very low internal resistance.
PC PSUs use 5V for PS_ON pull-up as they have the 5V Vsb (stand-by). But you can have anything up to 30V pull-up without any problems.
-
My bad, maybe I'm thinking of the old 0.6 boards and got muddled.
-
Duet 0.6 and 0.8.5 used BSH105 - 20V Vds and only 1A because of much higher internal resistance.

@dc42
If I were to use M589: Configure access point parameters would it connect to my all ready networks and if no network create it's own? Or dose this override all existing networks? -
@catalin_ro Yes, checked the schematics myself to see where I'd got it from and planning the interlock loop for the Duet 0.6 was it. Only changes on the Duet2 boards has been the addition of a resistor on revision 1.02 between the gate of the MOSFET and the processor.
