Brand new board not reading SD card

whosrdaddy

after a successful firmware update, DuetWifiFirmware.bin will be deleted automatically.
Are you able to connect to DWC or not?

TimVukman

Thanks for telling me that the file will be deleted.

So. WDC does not connect

I will be getting a Wifi Extender delivered tomorrow. just because I would like the signal strength to be higher.
It is clear that the board is connecting to the access point and thus my network.
I see no reason why the browser I use to connect to the duet wifi in the delta printer won't connect to the duet wifi in my cartesian.
I'm all ears. I would really appreciate an explanation and a troubleshooting path forward.

-62dbM is rather low. What WiFi signal strength does your other Duet report? Is the Duet in your Cartesian printer shielded by metalwork to a greater extent than the one in your delta?

TimVukman

Hi dc42

The Duet in the Cartesian is indeed shielded by metalwork. I put the power supply and board and external heat bed driver in an old desktop computer case that I had, with voltage / current meters in the space that used to hold the DVD. It really does look good, but I'd rather it worked properly.

It never caused grief with the other card, but I know that all wifi modules are not created equal. I will get rid of the case and see where things stand.

My Wifi on the delta with the other Duet card is 59dBm

TimVukman

I took the board out of the case for the cartesian printer. The M122 command reports -62dBm. M552 shows the board connected to the correct network and displaying the correct ip address.

I suspect that the readings for the signal strength are the same because while I was doing all my prior testing, I did not have the metal cover in place on the computer case. No matter, I am not going to put everything back inside it.

I have note yet received the Wifi signal booster.

Hi,
I am new here.
I recently purchased a Duet_Ethernet board and I am currently getting it set up.
Does the SD card have to be specifically formatted for the Duet?
I ask because I tried to copy all my files over to a larger SD card, but I get same symptoms as Tim.
Both cards have the same exact files, the original will work perfect, but the replacement won't work.

dc42

The SD card needs to be formatted to the FAT16 or FAT32 format.

You can test whether the new card is being recognised by sending M21 from USB or from PanelDue.

Kozlow

I thought you were on to something there, as the new sd card was formatted as exfat. So i formatted to fat32, copied files from original sd card over and pasted to new card and… no dice. Still won't work. M21 shows sd card in slot 0, with 59GBs

Hi:

Ok, I picked up my Wifi Extender and it is now configured and connected on my Wifi.

I have powered up the cartesian.

It connects to the Wifi

I have a network utility in my Avast antivirus software.
IP address 192.168.2.27
MAC 2c:3a:e8:0b:07:d2

Port 80 HTTP

The software idicates that the device is problem free

Wifi signal strength - 59dBm which is the same as my delta printer reports.

My browser connects to the Delta printer with no issues.

192.168.2.21
I backspace the 1 and type 7
Enter
Browser does not connect.

Suggestions?

FOUND IT!!!! IT'S OK NOW

I did a comparison between my two memory cards. On the Card that was not working, The directory structure with the folders that is supposed to be in the WWW folder was in the root.

I moved the files into the www folder, power cycled the machine and all it well. I am connected.

Sorry to waste so much of your time. I even confirmed the directory structure in the wiki and it is clear that the folders are showing in a www directory.

Really, I'm actually not this stupid normally.

Thanks for your patience!! I will never make that mistake again

Glad you figured it out TimVukman.
I wasn't trying to hijack you thread, I thought maybe our problems were related.
I guess not.

I figured out my problem as well, maybe this will help someone else.

When I formatted to Fat32, there was 16MB of space being left unallocated. That would screw the Duet up and wouldn't read the SD card correctly. It could see it mounted in slot zero, but that is it.

What I did to fix the SD card was run DiskPart, select and clean that drive, then create a primary partition.
Then formatted to Fat32 and was good to go.
