Any other suggestions? The vendor is not willing to replace my Duet under warranty until it is notated here - kinda frustrating that this is the only means of support - going on 2 days to get a resolution, who knows when I'll see a replacement if that's needed. Starting to regret this purchase...

It's a brand new board, just purchased from Filastruder.com in the U.S. It looks like its v1.04

Yes it does - I also tried with a known good 4GB card, and loaded it with the github SD Card contents file, verified the www & sys folders and files are present, but I get the same result. I can see the config file, but M503 shows its not found...

I tried that this morning, it reports back "SD card in slot 0: capacity 3.90 GB, free space 3.90GB, speed 20.00MByte/sec, cluster size 64kb"

Thanks again for the help

Hello! I'm getting the "Your Duet rejected the HTTP request: page not found" error. Previous posts led me to believe that the Duet could not locate the /www folder, which I verified via my PC was present. Sending M21 yields "SDHC card mounted in slot 0, capacity 3.96GB" I tried a known good SD card, reformatted with the github content. Still no luck. M503 returns "Configuration file not found"

I had everything plugged in and operational for a day. I had all motors and endstops configured correctly. The device still lights up as normal, and I can interface via USB, however it cant read the config file.

Help would be appreciated.
