Duet 2 Wifi/Ethernet + SBC (RRF 3.2)

TopperHarley

Hello,

as far as i know RRF 3.2 will be released soon and support (officially?) Duet 2 Wifi/Ethernet + SBC. I discovered this very long and interesting thread with some nice approches how to connect Duet 2 to SBC https://forum.duet3d.com/topic/17203/duet-2-ethernet-and-sbc.

There are any plans for an official adapter PCB or a detailed manual how to connect SBC to DUET 2 Wifi/Ethernet?

Best regards
TopperHarley

If more than 10 people want an adapter in Europe i would make some! Best

i doubt they'd be able to sell a board much cheaper than ordering one yourself from https://forum.duet3d.com/post/178134 jlcpcb even does the smt assembly for ridicilous prices; or gang up to split the costs like PCR suggest. (the design is the same as on the duet3 mini/duet 3 6hc)

as for manual, what the thread you linked to doesn't cover the RRF3 and Duet3 documentation covers

(incidentally, if random norwegians need one, hit me up)

I also in the process to "update" my duet 2. I have ordered a few pcbs and currently I'm waiting for the components, so as soon as I test them I could sell the spares.

I'm from Europe (spain) BTW

May I ask if someone is so kind to summarize the firmware related steps neccessary to connect a Duet 2 Wifi to the SBC?

I connect the Duet 2 Wifi to the RPI4, removed the SD card from the Duet but obviously stucking to install the firmware. Read all the realted posts but are quite confused currently

Thanks!

I have ordered some of these nice PCBs by @deadwood83 for Duet2-Ethernet at JLCPCB: (PCBs are full by JLCPCB)

(Big thanks for the great work!)

Because i only need one of these, i have to share 4 to the community. So if you live in germany, fell free to contact me.

@martinnyhc Perhaps best to start a new thread and detail how far you've gotten and where you're stuck.

@martinnyhc follow https://forum.duet3d.com/topic/20576/duet-2-wifi-ethernet-sbc-rrf-3-2/1 to flash this firmware file: https://github.com/Duet3D/RepRapFirmware/releases/download/3.2.2/Duet2Firmware_SBC.bin

MartinNYHC

@resam Already did that. What I see is

@martinnyhc Flashed the board again and now it looks different.

Hi @TopperHarley ,
I've been wanting to try JLC PCB for ages but have no idea how to go about it.

Could you please give me some advice what files etc I'd need to provide from the linked pages to get a fully assembled board.

I guess I could get a few made up and share in the UK if there is demand.

Many thanks

I changed the frequency to 200000 in config.json and the connection is now established
