Send G-code file through USB
-
Is there a way to connect my laptop via USB to a Duet WiFi and transfer gcode files that way? I have completely given up on DWC today due to non-stop connection issues.
-
You can't transfer a file over USB to the SD card, but you could use a Gcode sender program like octoprint to stream a gcode file to the Duet but you lose a lot of features that way.
Would you like to troubleshoot your connection issues?

I had just typed a long reply with all the information I thought would be relevant, but think I figured it out.
I brought the machine from home to work and connected to a new Wifi network with YAT. It would connect, but never stay connected. Only long enough to send a command through DWC, but not even to upload a small gcode file.
After checking the config, it still had my old wifi credentials. After updating manually, it has seemed to stay connected. If I start having problems again I'll report back, but it seems resolved for now.

@plasticfactory I spoke too soon. Perhaps I was optimistic as this was the longest it had stayed connected, but it is now losing connection with higher frequency.
DWC: 3.1.1
Firmware: 3.0I'd prefer not to change my firmware for a several reasons, but suspect that will be the first suggestion.

@plasticfactory said in Send G-code file through USB:

My first guess is that your work network is configured in a way that prevents the Duet from keeping a connection.
Is there something your work people know about that network that's a bit different?
-
@alankilian That's certainly a possibility. The man to ask is an office over -- do you know more specifically what I should ask? This is not an area I'm particularly knowledgeable.

I know corporations sometimes do strange things with their WiFi networks, so I would just tell him/her that you've got a 3D printer that worked at home and keeps getting disconnected at work.
They might have connection logs that could tell them something about your connection.
Also, sometimes they setup a dozen WiFi access points with the same SSID and you might be connecting to one farther away. Sometimes they have a way to connect to a close one.

@plasticfactory probably not related, but it's not a great idea to include the M587 in your config. The network SSID and password gets written into the WiFi module, so you only need to send that the very first time you connect.
Including it in config.g means the WiFi module will have a bunch of unnecessary read/write ops every startup.As a short-term work around, might be worth switching it to access point mode to avoid the work network issues?
-
@alankilian Thanks for the suggestion. They are looking into it for me, and have identified a potential access point issue (all appear to be working, but only one appears when logging into the controller). I'll report back on this one.
@engikeneer Thanks for the tip, I had no idea. I'm reading up on access point mode now.

@plasticfactory yes it's possible to upload GCode files over USB, but not common to do that. See the M559 and M560 commands.
