API Key to send Gcode from Orca Slicer to DWC

[Endur]

Hello,

I have just completed my DIY 3D printer build, and it works!

But I'm having trouble sending G-code from Orca Slicer to my 3D printer. I can save the G-code on my PC and upload it to DWC through Orca Slicer (Device Tab), but I can't upload directly from the preview tab.

I believe it's a problem with the wrong API key, but it could be me not understanding how to set this up.

Does anyone know if the problem is the API key and, if so, where I can find the correct one? The error i get is this and the API key I using.

Setup: Duet 3 Mini 5+ and RasPi 3B+ as SBC.
Firmware: version 3.5.2

Thank you in advance.

@Endur you don't need an API key unless you have a password set with M551 https://docs.duet3d.com/en/User_manual/Reference/Gcodes#m551-set-password
I have used orcaslicer to upload files in both standalone and SBC mode recently with the latest 3.5.2 without issue
Additionally orcaslicer may be having an issue resolving the host name using mDNS. Try the IP address address as well

@jay_s_uk there's a case to be made that RRF should warn but not error for an API key if none is needed, but the security person in me also says it should probably error so people stop sending secrets by accident.

@jay_s_uk That makes sense.

Do you use "http://duet3.local/" as host name and "Duet" as host type?
Im get the "Error 6" in Orca and I think is related to Host name.

@Endur I use the IP address rather than the mDNS name
