12V on the 5V rail
-
@bearer Ok!
Yeah, It is a V1.03 board.
Is it possible that the Wifi Module and the SD card reader is OK or do I have to change one/both of them as well? -
@Haggan90 as I said I'm not sure, head isn't quite on the right way but I'm guessing you essentially fed -5v into the 3.3v output of the regulator which it didn't like.
odds are if nothing else got warm the damage is contained, but as i said, remove the wrong regulator and test it with an external supply and you'll have the answer.

but should be compatible with AP7361C-33ER-13
@Haggan90 just clicked in my head the AP7361C doesn't specify if the tab is connected to v-out or gnd or anything at all; so I can't say for sure if it works.
TC2117-3.3VDBTR is the full partno from the 1.03 schematic.

TC2117-3.3VDBTR
IS this the correct one?

has the same manufacturer part number as on the schematic at least, so thats about as sure as I can get.
"Tillverkarens artikelnummer TC2117-3.3VDBTR"
(the key to decoding the part numbers are usually towards the end of the datasheets, helps decode the various letters and numbers)

@bearer Hi!
I have now changed the U2 and I can connect to the board via USB
It seems like maybe the WiFi module is broken, but is there any way I can check that over YAT? -
just follow the getting started guide to set up wifi again, if it responds to M552 and connects you're good.
-
@bearer ok!
The blue LED does not light up on start, is that a bad thing? -
@Haggan90
Ok, it seems like I can't get the Wifi module into idle mode.
Also, I do belive it get's a bit warm, not hot but warm.M115 FIRMWARE_NAME: RepRapFirmware for Duet 2 WiFi/Ethernet FIRMWARE_VERSION: 2.05.1 ELECTRONICS: Duet WiFi 1.02 or later FIRMWARE_DATE: 2020-02-09b1<LF>ok<LF> M552 S-1 WiFi module stopped<LF>ok<LF> M552 WiFi module is disabled<LF>ok<LF> M552 S0 ok<LF> M552 WiFi module is being started<LF>ok<LF> M552 S0 ok<LF> M552 S0 ok<LF> M552 WiFi module is being started<LF>ok<LF> M587 M587: Failed to retrieve network list<LF>ok<LF> -
@Haggan90 try deleting all saved wifi networks with
M588 S"*"(That is, using an asterix for the network name), then re-adding it with M587. For example,M587 S"networkname" P"password". -
@Phaedrux Hi, I get this:
M588 S"*" M588: Failed to reset the WiFi module to factory settings<LF>ok<LF> -
@Phaedrux The SD-Card seems to be fine.
Do I need a hot air desoldering station to change the Wifi Module? And, what would I need to do after I've changed it?

A good preheating and some quickchip or similar 138C-ish melting point solder might to the trick; but most likely "yes".
edit: oh, and after all you need to do is run M997 S1, presuming the wifi firmware file is in the /sys folder on the SD card.
-
@bearer Thank you! I will see what I come up with to desolder it
Is there any special version of the ESP-12S Wifi Module I need? -
@Haggan90 said in 12V on the 5V rail:
ESP-12S
Thats about as specific as you can get, but no, any ESP-12 ought work, the 12S has all the right certifications on it which is important for Duet3d selling them, not so much for you. I.e. you could use a 12E or F if easier to obtain (or pretty much any other ESP with the same footprint)
(the ESP-07S is an official option if you want external antenna, just make sure to never run it without antenna attached to avoid damage to the rf tx)
-
@bearer Thanks!
I just ordered a ESP-07S as I have a bunch of these antennas laying around, hoping for a bit better range on the WiFi then -
Manage to desolder it using a regular soldering iron, now I just need the new chip!
-
@bearer Woho! It's working again!
Thanks for all the help! -
Well done! I'm sure the planet prefers a bit of repairing to just landfills:)
-
@bearer
Unfortunalty is seems like the Duex2 took a hit as well, as I can't get the steppers working there.
Nothing get's hot on the board.
Any idea what could have broke on the Duex2?
