Using Raspberry Pi3 with Duet 2 Ethernet
-
Hi,
the easiest way is to use a bridge. Something like this (small, enough bandwith):
Costs about 20 euros and can be powered over the 5 Volt pins of the duet.
I'm using it with my maestro and it's perfect.

Whilst I totally agree simplicity is better, there are situations where it makes sense.
When you are already using the Pi for other things eg motioneye for remote monitoring / recording or octoprint etc.
I would prefer to minimize additional components. -
All are great solutions to various scenarios... @incogizmo hit the nail on the head for my scenario, I am using something similar to motion eye to stream jpegs to DWC. I also have 5 RPI3s, about 10 USB Wifi adaptors and other little tid bits. I have a monoprice duplicator 6 with a Duet WiFi and love it. I just decided to give the Ethernet version a shot on a whim. Who knows, I may come up with other ideas where the RPI3 will come in handy.

Here's another possible and much easier solution... use "socat" to bridge the ports...
Give the duet and the pi ethernet port static addresses say 10.0.0.2/24 and 10.0.0.1/24 respectively then run socat as follows...
socat \ TCP4-LISTEN:80,bind=<pi_wifi_addr>,reuseaddr,fork \ TCP4:10.0.0.2:80,bind=10.0.0.1Now any connection that comes in over wifi to port 80 will get forwarded to the duet's port 80.
