Maybe there is already a thread concerning my problem, well I didn´t find it. In feb. 2017 I ordered a Kossel-XL from a distributor from the Netherlands with a Duet Wifi board (343/500).
Well, first the board did its job very well although the board just was configured for a Kossel-Mini. First I changed this configuration which worked well more or less.
Then I found a config.g in the download space on the page of the printer distributor for the KosselXL / Duet combi.
I made an upload of this config via the web interface on the board. Well, what can I say: what a stupid idea. After that nothing works anymore. No web interface, no connection to pronterface, nothing.
OK, I said to myself, it’s time for a firmware update. The usual procedure doesn’t work cause there was no web interface. Fallback procedure #1 and #2 doesn’t work either for some reason. The Windows-PC didn’t see the Duet board. But… option #3 seems to work. With the SAM-BA 2.16 the PC sees the DuetWifi (Yippeeeeee!).
After sending the fresh downloaded DuetWIFIFirmware.bin (1.18.1) and proceeding the other recommended steps I pressed the Reset bottom at the board followed by the typical “pling-pong” sound when a USB-device is disconnected, also the “Diag-LED” turns off.
Connecting the board via pronterface was still not possible.
After spending quite a couple of nights trying to fix the problem by myself now I´m desperate.
How can I fix the problem, what was my mistake? Is it possible to get back the state of delivering at least?
The distributor in the Netherlands is: http://builda3dprinter.eu/ There you also can find the config.g where the trouble began with.
