Thanks for your time dc42!

Just got my power back on. The error is this. "Failed to upload XXXXXXXXXXX file. Network error".

But now after the power failure it loaded fine. Must been the router??

Can I just move it to the SDC directly?

I tried uploading just 1 file and it gave me the same error!

I have a new Duet 3 6HC board and tried to upload the Duet2and3Firmware-3.1.1 file and keep getting this error.  I must be doing something wrong.

Thanks DC42!

Thanks for the information. When power up the board for the first time should I connect any stepper motors? I most likely need to update the firmware's.

I am newbie to the Duet controller boards and have a question about the new Duet 3 HC6 board. How do you get to the DWC from my computer. Is there an default IP address or Hostname?
