try without the sd card or config.g on the card?

This post is deleted!

arhi

missed the second part of the https://duet3d.dozuki.com/Wiki/Getting_Started_With_Duet_3 page sorry .. everything works ... so must boot duet2 without sd card to work with sbc - great

@arhi said in Duet 2 Ethernet and SBC:

or remove/rename sys/config.g - sd card in itself isn't a problem, but valid config file is.

arhi

@bearer yes, but in that case better remove the card completely

is the "simulate job" doing some spi communication here talking between sbc and duet or is executed on the sbc only? I connected everything on my spare duet that's not in any of the printers so simulation is the best I can do (running one 50MB file right now)

A Former User

@arhi said in Duet 2 Ethernet and SBC:

anyhow another issue, the excess pcb I left to not have sbc connector right on the edge (kill me why) is a problem with a heatsink .. not a huge issue but something to be aware ..

could you get away with using a regular right angle connector and solder it smd style to pads on the top and bottom of the board?

yes, that would work but I hate those comb soldering + it would require thicker board to properly work, also I don't think I ever seen 90 degree female double header, usually male is 90 degree and we need female here.

Thing is, there's nothing important between connector and edge of the board, I can just move the connector closer to the edge (cut the edge closer to connector) but for now it's not a big deal since I just used another rpi that does not have active cooler on it and the passive heatsinks are more than enough as this will be in a box with duet that will have active cooling anyhow so air movement will happen for sure ... also, dunno when plugins will come but for now load is very low so rpi is rather cold

now question is how is simulation related to real stuff wrt sbc/duet communication

The simulation runs on the Duet, so the SBC to Duet traffic is much the same as for a real print, except for fewer status requests/responses because of the shorter duration.

Great, so I can assume this "link" between SBC and Duet2 is stable.
I intentionally put a DCDC close to the "link" and I have these long pins sticking out like antennas so "worse case scenario" and after the relativly long simulation I don't see any errors in the log. When I trim the pins and remove the DCDC from there it should be even better :).

Awesome

btw, another question. How does the SBC+Duet work now? Similar to klipper where SBC is calculating paths and duet just executing stepping table or more like octoprint where SBC is streaming G-Code to the duet and the path calculation is executed on the Duet? (I know it's not identical to neither of those two but those are 2 extremes)

GCodes are pre-parsed on the SBC and certain operations (e.g. macro expansion) are done on the SBC. The motion calculation is done on the Duet.

@dc42 nice, so closer to octoprint than to klipper but unique ... /me like

I really like the Idea to use a SBC with the Duet 2! Really great work! Are there any plans to offer some official adapter(s) in future? (maybe in the DUET-Shop?) I'm ready to pay for such a nice solution like the adapter made by @arhi or @deadwood83.

v0.2

changed the shape of the board
re-routed the comm tracks so that there's even less crosstalk
cut the excess pcb from the side of the connector so that it does not interfere with those big heatsinks on SBC
added 5V connector for SBC

Unfortunately it still does not clear panelDue and Probe connectors. I was thinking about changing the relation between duet and sbc connectors (to move the duet connector more towards other end of the sbc connector) but that would move the SBC more out of the allignment with the duet, already the SBC is 6mm in front of duet messing up the case design so looking at that I should move the connector the other way 6mm making access to those two ports even more problematic... so I'm leaving it as is. The way board is now shaped the cable from the probe port can come out but you either need to use the long pins for the duet connector or you need to desolder paneldue and probe connectors from duet and solder in 90 degree ones (this is what I will be doing myself)
