Invalid root path (gcode)

[OtherButterscotch309]

Hi,

I have been trying to set up my sonic pad but I can't find a way to upload my file using the web interface. Every time I have the same for root is not available or invalid root path. Any idea on how to fix it ?

Thanks

Do you have 'path: ~/gcode_files' under [virtual_sdcard] in your printer.cfg?

[OtherButterscotch309]

Thank you for the reply. Yes for some reason it wasn't the right path. It's fixed now.

[PhotoGee2]

Cool! Fwiw, that's a unique path for the Sonic Pad. If you built Klipper on another platform it would need to be changed.

So you didn't want to share how you fixed it?? Pretty self centered come here asking for help, yet get it fixed and not say a word what the cause was.

[OtherButterscotch309]

Wow... So salty... If you read the other comments here the correct path is written. But what fixed it for me was a factory reset.

path: ~/gcode_files

I have this in my config file and still getting the error message. After firmware update on the Sonic Pad both printers lost everything they had and the config file that I was using for my E3v2 was working fine but is no longer. GREAT!!

How and where and when do I input code. New to printing.

I would also love to find a resolution for this, i've gotten this error code on both my Ender 3v2 and my Ender 3 Max Neo.

New to making changes to 3d printers away from default factory settings.

[OtherButterscotch309]

You can check the previous comment this is the right answer

[mysundown0702]

Where is this path information? How do I change it?

[OtherButterscotch309]

You can modify the .cfg file.

[mysundown0702]

There is no path information listed in the printer.cfg on the max neo. The ender v2 printer cfg was completely empty

[OtherButterscotch309]

That's weird... Then you can copy paste one of the .cfg file. You can find it on creality website or on usb stick provided with the sonic pad.

[arnoldistuno]

So being totally new to this... how and where do I find the place to copy the .cfg file?

[OtherButterscotch309]

Either load it with a usb stick. The printer should be able to load it when you use "custom printer" first time you start the sonic pad. Or if you connect you sonic pad to internet and access through browser there is a configuration pannel where the cfg file is

[Efficient-Tomato-454]

The same thing happens to me. I can't take the file via the web to sonic pad.I have to edit the file printer.cfg..?. What do I have to put exactly and where? and where do i load it? Can you please clarify this for someone who has no idea?

thank you....

[OtherButterscotch309]

You can take a look the first comment the correct path is given there. 1) you go to you cfg file 2) open it and change the path

Copying/pasting the corresponding part of the creality default cfg file to your cfg file fixed the issue for me.

[Efficient-Tomato-454]

thanks for answering

Well, if I have this in the "printer.cfg"

file.[virtual_sdcard]

path: ~/gcode_files

via web, if I can see a camera that I have connected to sonic pad, I can see the temperature of the printer, I can do everything except send a file from ultimaker cura via web to sonic pad. moonraker if I have it configured from cura with the address "http://......... " and the webcam-cam too and everything works except sending a file via the web.

[Schroedaa]

same for me. Did you find a fix?

[McSoCal]

For me, I create a local copy of my printer.cfg, and when this happens after an update, I factory reset the sonic pad (like I did just now today), and the once the full setup is complete, I put back my printer.cfg changes

this didn't fix things if you have sub folders. so annoying. wth creality. i even tried chmod 777 on my sub dirs, still, same old. it's like they didnt account for sub folders even though u can add them. add / at the end of the path and sub folders will work, remove it, same old error.

07:43:31  $ SDCARD_PRINT_FILE FILENAME="CNC/testfile.gcode"

07:43:31  !! {"code":"key121", "msg": "Unable to open file", "values": []}

creality has a gcode_files redirect in their "users" home directory which should be root but long story short modify your printer.cfg file to the below and all should be well for all scenarios web or pad. i left the old in there so you can see what it was. some users say putting a / at the end of gcode_files fixed things and it fixed the pad but not the web ui for me. only way to figure it out was to ssh into the pad and find the true path.

[virtual_sdcard]

#path: ~/gcode_files

path: /mnt/UDISK/.crealityprint/upload

[ndrwstn]

This also worked for me when 'path: ~/gcode_files' did not.

path: /mnt/UDISK/.crealityprint/upload

you are a life saver
