config.g disappears

norwestie

@phaedrux I connected my MacBook Pro to the board, the two LEDs next to the USB, the red and green are illuminated, also the red blinking one near the corner is on. And I can connect with SerialTools. But no LEDs on the ethernet port.

Phaedrux

In serial tools are you able to send M552 S1 to enable networking? That might get you some action on the ethernet port.

norwestie

@phaedrux said in config.g disappears:

M552 S1

Yes, it did! I'll see if it works powered through VIN.

It does not work. I did:
Send M552 S0 to disable networking, then M552 S1 P0.0.0.0 to enable networking and have your router assign an IP address and it reported back good.

Connecting to DWC again with Mac and looking at System, there still is no config.g and I had copied it there an hour ago.
Again, reloaded config.g and it appears to be working, for now.

Phaedrux

It's strange that only config.g would be missing. I'd expect any card issue to make the whole thing unaccessible and DWC wouldn't work at all.

I would suggest getting a fresh SD card and copying your files over to that one and see if it holds out longer.

@norwestie
I remember, I edited my config.g on my PC and saved it. But it was named

config.g.txt

Had to rename it in a DOS shell (Mac is different) and then could use it on my printer.
IIRC DWC can also rename files with wrong file-type letters, just have to find it.

Michael Hathaway

I also had this happen recently on the Duet 3 mini 5+. I lost ethernet connection at the same time. I checked the sd card to make sure it was seated and loaded the config.g back on. If it happens again, I will pull the card, inspect closer and report back.

peter247

@phaedrux it is when you are editing config.g and you press save and it drops the connection while saving it and you get a blank config.g when it reboots.
It only happens to config.g because that is the only file you are editing , I guess it could blank any file you are editing ?.

jay_s_uk

@peter247 if it fails during the upload process you're typically left with a config.bak file, that can be renamed config.g

peter247

@jay_s_uk The problem is you can't connect back into my duet so you reboot it and the config.bak now automatically overwrites config.g , so now config.bak and config.g are both blank .

jay_s_uk

@peter247 yea, sd card removal is typically required. i'm surprised config.bak is being overwritten though as it only gets created by DWC when the existing config.g is editted. its not automatically created by the firmware on boot. but ultimately, always keep a backup of your files as sd cards aren't the most trustworthy devices

Michael Hathaway

@peter247 My machine was off for the night, but my duet interface was still open. When I turned the machine back on, there was no connection. When I finally regained connection, config.g was missing. I replaced the card just to be safe.

Phaedrux

@Tinken @peter247 What board are you using? Can you share a M122 as well?

peter247

@phaedrux

It is for a Blv mgn cube which I'm still building , so it never been fully tested out

Could everyone in this thread who has had a config.g file go missing, can you please answer me these questions.

Was it just the config.g file that was gone, or other files as well?
At some point close to that time had you been editing config.g via DWC?

dino1

@tinken Yea my brand New Duet 3 mini is doing that. Lucky for me my friend has a exact clone of my Printer. His Duet 3 mini works great, but mine the Duet 3 mini is crazy as my friend said to me. My Duet 3 mini freezes and the Config file is no more. We think it a bad card reader on mine. as we swap my Duet 3 mini with his and his works perfectly on my Printer. My duet 3 mini has the same problem when we try it on his printer. Please note all firmwares and printers were 100% the same and we tried new SD cards. Also no editing config.g via DWC at the time this was happening. Also It looks like more this just the config file is gone, some time other file go with it.

Michael Hathaway

@phaedrux Just the config.g missing, nothing else. I was editing the config.g via DWC the night before. I didn't notice the missing file until I turned the machine back on the next day.

o_lampe

@Phaedrux
Just wondering when config.g.bak is created/overwritten? The very moment, I click on edit config.g or when the printer is powered up?
I'm puzzled, because I read that an empty config.g would cause an empty config.g.bak after startup?!

jay_s_uk

@o_lampe its created on edit

o_lampe

@jay_s_uk said in config.g disappears:

@o_lampe its created on edit

That would make sense, but would imply that this action goes wrong and ends up with an empty .bak file.
A simple routine

[pseudo code]
if filesize.config.g > 0 
    => write backup file
else 
   echo " warning, SD card read failure"

would help...
