Change Wifi via Config?

AS-3D Druck

Hi there,
i recently got a new AVM Router and forgot before to change my Wifi Settings and i wonder
is there a config File or something to change the Password without connecting my Duet Wifi to my PC?

A Former User

using a macro is the recommended way https://forum.duet3d.com/post/139882

but that thread also has examples of using config.g which is not recommended.

I know, but my USB Port on my Duet Wifi is broken and i need to do it from my SD Card.

seems the trick was to add the G4 delay, but the details are in the thread i linked to.

So if i just add this to my config at the Bottom it should work right?

M98 P0:/Macros/WifiReset.g
G4 S5 ; wait 5 seconds
M98 P0:/Macros/WifiClear.g
G4 S5 ; wait 5 seconds
M98 P0:/Macros/WifiReset.g

(I created the Files i call here with the Code from the Linked Post)

That ***** me off... so I tried on a board here.

Think the second G4 is redundant, but uncomment if it still doesn't work. Confirmed working from config.g even though its baaaaaad mojo.
M552 S-1
M552 S0 ; take AP out of reset, just in case
G4 S1
M588 S"*"; forget all previous access point info
;G4 S1
M587 S"---" P"---" 
M552 S1

replace ---- with your ssid and password will clear old and add a new network. remove/comment out M588 to prevent clearing old networks.

Didn't work i don't know why...

tryed at the End of my config.g File:

first:
M98 P0:/Macros/WifiReset.g

; WifiReset.g
; Use in case wifi module is not running. (Blue light off)
;
M291 R"Reset wifi module? Y/N" P"Caution. Will cause pause in print" S3 T10
M552 S0 ; Disable network module
G4 S5 ; wait 5 seconds
M552 S1 ; Enable network module
M291 P"Wifi module reset. Check console or DWC."

second:
M98 P0:/Macros/WifiClear.g

;WifiClear.g
; Clear all wifi networks
;
M291 R"Clear WIFI networks? Y/N" P"Caution. New network must be added." S3 T10
M552 S0 ; Disable network module
G4 S5 ; wait 5 seconds
M588 S"*" ; Clear all saved wifi networls
M291 R"WIFI networks forgotten." P"You must add a new WIFI network."

third:
M98 P0:/Macros/WifiAdd.g

; WifiAdd.g
; Add default wifi network
;
M291 R"Add default WIFI network? Y/N" P"This will add duetwifi access point." S3 T10

M552 S0 ; Disable network module
G4 S5 ; wait 5 seconds
M587 S"myNetworkName" P"NetworkPassword" ; Add duetwifi SSID to remembered networks list
G4 S5 ; wait 5 seconds
M552 S1 ; reenable wifi module
M291 R"NetworkName added." P"Check console to verify IP address."

What was wrong? (And yes i changed my NetworkName and NetworkPassword to my)

hmm, seems i didn't look too closely at the macro Phaedrux made - M291 without a display might not be a good fit, comment out and it should proceed.?

tried it again without the line M291 and no success

The down side is the error messages will be on the usb console; if you have a 3.3v usb ttl adapter you can hook up to the PanelDue port

I can only attest to the 7 lines I tried myself beyond that idk.

So no other way?

Three other ways:

If you have a PanelDue, you can use it to enter the M587 and other commands.
In your config.g file include M552 S0 to put the wifi module into Idle mode. Then set up a trigger on one of the endstop inputs using the M581 command, and in the trigger file execute the M587 command, followed by M552 S1.
Recent 3.01RC firmware releases run the file sys/runonce.g after running config.g. You can put the M587 and other commands in runonce.g. The file is deleted after it has been run.

@dc42 The only option that i have is the 2. Way cause it runs on Version 2. something and i got no external Display.
I understand kind of what you want but don't know how to do it.

Does this help?

The macros from that other thread assume you have a PanelDue to be able to use them as is, or a USB terminal with some modification.

i suspect there is a problem either with the duet or exteral to the duet, because it worked when i tried it on 2.02 and 2.05

are there any special characters in your ssid or key, hidden ssid, brand of router, type of encryption etc?
