Solved Problem with Duet 2 Wifi
-
I am having a sudden problem with Duet 2 Wifi. I have a Blown 1A Fuse, DWC says, "No Tools" and Console says, "Warning: VIN under-voltage event (9.5V)". I have checked the voltages at main and get 24.18V. I am running firmware 3.4.5. Here is the results from Diagnostics:

@mesacrash have you replaced the fuse?
Owns various duet boards and is the main wiki maintainer for the Teamgloomy LPC/STM32 port of RRF. Assume I'm running whatever the latest beta/stable build is
-
@mesacrash Yes and it still doesn't work.
-
This post is deleted! -
How did you blow the 1a fuse?
When you do see the under-voltage error?
-
@Phaedrux I turned the machine on. When I noticed the problem on the DWC, I started checking and discovered the blown fuse. I ordered fuses and replaced it but still have problems. However, the new fuse is still good. The under voltage is listed in the console.

Can you share the config.g from the system tab? It seems like you have nothing configured, which may mean the config.g is blank/missing?
Is this a new build, or an existing build that was working fine up until now?
Can you get some photos of the top of the board and look closely for any damage spots?
-
@Phaedrux I cannot share the config.g from the system tab. It is an existing build that was working. The config.g file folder was empty. I copied the bakup and placed it in the empty folder, saved it and mounted it in the board. Now I get this message in the DWC; Your Duet rejected the HTTP request: page not found
Check that the SD card is mounted and has the correct files in its /www folder -
@mesacrash said in Problem with Duet 2 Wifi:
The config.g file folder was empty.
You mean the sys folder was empty when you looked at the SD card in your computer? Or just the config.g file was blank?

-
@Phaedrux There is a www folder, with stuff in it, but I don't know what is supposed to be in it.
-
@Phaedrux Just the config.g folder was empty.
-
@mesacrash said in Problem with Duet 2 Wifi:

You mean file right? There should be no folder inside of the sys folder on the SD card.
Can you post your config.g.bak file that you renamed to config.g?
-
@Phaedrux Yes, in the sys folder was the config.g file, which was empty.
-
Can you send
M20 P"/www/"and see what it responds with? It should gives you the contents of the www folder. -
@Phaedrux I can only send via YAT:
M20 P"/www/"
Begin file list<LF>NONE<LF>End file list<LF>ok<LF> -
@Phaedrux If I put the SD card in my computer, I can see folders and files.
-
@Phaedrux I remembered that I had an archive of the original SD card. I found there was a folder missing from my operational SD card. I put the folder in it and it still won't work. The board seems to know the SD card is mounted but doesn't recognize there are files on it.
-
@Phaedrux This is the second time this has happened to me. The board in the machine is a replacement for the first board. 3dWorld replaced the first board, should I contact them, perhaps? The first one lasted about a month. This one has been running about 5 months. And running well, I might add.
-
The first one blew a fuse as well?
Can you post some close up photos of the board please? Perhaps we can spot some damage.
It would be a good idea to find out what is shorting a damaging the boards before replacing it again.
