Duet 2 Ethernet and SBC

GeneRisi

@resam Is anyone ordering a batch of these boards and doesn't need all 10 of them? Please PM me if you want to sell one. I'm in the US. Thanks!

FYI - I found adding a simple ferrite core to the cabling from the Duet to the Pi has silenced the SPI errors.

I have a ~10CM run with shielded cables, but I guess it's still noisy there, but that core appears to have reduced the noise enough to bump the frequency back to 4MHz. Haven't tried the full 8MHz yet as I want to get some prints finished before I do anymore testing.

@keyz182 Could you post details of the type of core you used and perhaps a picture of how you have it installed?

@gloomyandy can't get to the back of the printer right now. As for which ones, I litterally typed "ferrite core" into Amazon and bought the first ones that came up. Just clipped them straight onto the cable. I did have to trim the insulation a bit as it was a bit too fat ( I have a pair of 4core shielded cables, so trimmed the outer insulation). If you have loose cables, they should just fit, all of them through the one core.

It came to mind as I had to do the same with my Paneldue. It's got maybe a meter of cable to it, and it was very intermittent without the core

@keyz182 Thanks! So I guess it was one of those clip on versions rather than a ferrite ring? Assume you just passed the wires through once?

keyz182

@gloomyandy yup, the clip ons, and just the once.

I have ordered some boards from @deadwood83 at JLCPCB.

If you are from Germany and need one, feel free to contact me: https://forum.duet3d.com/topic/22545/3x-duet-2-ethernet-sbc-adapter-to-sell-germany-only

Hi @topperharley, I'd like to order some for my Duet ethernet from JLC for myself.

I'm in the UK, but I have no idea how to go about it. Is there a brief summary (for a total JLC noob) of what I need to do? I've created an account but am not sure where to go from there.

Hello guys!

I have installed the SBC daughterboard from @deadwood83, because i want to switch to SBC mode later with the next release of RRF. It seem like my printer can't access to my network anymore with the installed daughter board (running standard image Duet2CombinedFirmware.bin 3.2.2).

I was expecting there should be no issues running the standard image with installed SBC daughterboard.

@cncmodeller I am also a noob to JLC and wonder the same thing!

@generisi maybe open a topic in "Off Topic" category ... that would make much more sense.

JLC service works just like any other pcb manufacturing service, you send them gerbers for layers and drill files for holes and they make you pcb's... if you want assembly you generate BOM files and position files (what and where) and they get you the parts and solder them on boards ... everything is properly documented on their site

@arhi Thank you very much! I just ordered 5 boards

@arhi @PCR @deadwood83
Sorry for digging out this old thread, but I was curious if it would make sense to make a Duet2 adapter board for the RasPi Zero 2W?
@PCR has already made an adapter for Duet3 (mini), but IMHO it would be easy to combine it with the circuits mentioned here.

Unfortunately I'm still a NOOB in KiCad, but maybe I can trigger someones interest?

I have very bad experience with rpizero boards so...

As for the duet2+sbc, I made this for test, it worked and I let it be, I focused on making some adaption software as external network app and not something that would run on sbc... and that was looong time ago (from when this thread was live) and since then I maybe had 2 hours of printing time total .. too busy with work ... hopefully I'll be able to come back to 3d printers in spring but I got me some resin printers dunno if I'll spend much time with duet boards I want to spend some time with them first

@deadwood83 do you still have some kit left for sale? in need of one for my duet 2. are the chip already soldered?

I'm still hopeful someone will post instructions I can follow for converting a Duet2Ethernet to d2+SBC as I'd like to have the extra processing ability for some of the hoped to have plugins.
