Duet2 Wifi and Duex Suddenly Won't Connect on RailCore

JeffAGreen · 16 Mar 2020, 23:15

Duet2 Wifi and Duex on a RailCore - CoreXY. I'm a newbie, in the newbiest sense. I had the cards working great. I had JUST finish tuning all the settings - and of course, hadn't backed up my config file. Then, for no apparent reason, the printer stopped connecting to the DWC interface. If I use the USB and connect with YAT, I can get it to tell my my fireware and such (see screenshot) and it will connect to my wifi and even show up on my IP list on the router. But when it's plugged into the USB and I try to connect with DWC, I get this: 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. If I disconnect the USB, DWC just says it timed out. Is this just an SD card that went bad? I tried typing M503 and I just get OK. No other feedback. I don't pretend to know a lot of gcode. Just learning on the fly, usually when something goes wrong.

check that the DWC files in /www on the SD card are there? or just extract a fresh copy?

How do I do that? Can I do that from YAT? If I try to look at it on the PC, it wants me to format it.

Your card is dead I think. Format it and try another config set. Or try another card entirely with another config set.

What does M122 tell you in YAT?

https://www.sdcard.org/downloads/formatter/ that ensures windows doesn't try to be clever.

use the "overwrite format" option if you can't replace it. takes a while 10-30 minutes maybe.

(maybe run M20first just to rule out issue with the computer, but sounds like the duet is also struggling with the card)

@Phaedrux This is what I get. I don't think it sees a card.

JeffAGreen · 16 Mar 2020, 23:40

@bearer Thanks. I have already started that format process. I have SD Card Formatter for the Pi. Where can I get some really clear instructions for getting the system back on the SD card that doesn't assume I know what I'm doing? I was able to follow the instructions for getting the firmware updated, but that was not started from scratch. Once I get to DWC, I was much more comfortable in learning how to make changes.

@Phaedrux Right. That part I understand. I mean, to get the software back on the SD card to run the duet.

RepRap configurator may be the simplest way, but all it does is offer you a link to download DWC to put on the card.

which is basically to download https://github.com/dc42/RepRapFirmware/releases/download/2.05.1/DuetWebControl-SD-2.0.7.zip and extract the files to the new SD card so you have /www/index.htm.gz (and all the other files ofc)

Then when you connect with YAT and enable networking you can continue with configuriring through the web interface creating a /sys/config.g (or use the RepRap configurator).

Well the folder structure is here: https://duet3d.dozuki.com/Wiki/Firmware_Overview#Section_SD_card_structure

The firmware is already on the duet, it doesn't live on the SD card.

The web configurator will get you the config files.

And bearer linked to the DWC files, which should also be present in the firmware release.

@bearer M20 shows 0 files.

it would when M122 said the card wasn't detected, its just less noise in the output with M20 if the SD card is the sole focus.

seems a new feature offers links to download the correct files at the end of the configurator

and then
