Duet 2 Ethernet and SBC

arhi

@Dougal1957 the whole kicad project is attached to my original message, now, that handles the gerbers, I'll check if I stored the original bom and placement files (I think I killed them after the upload but they are easily regenerated there are only 4 parts on the whole board) ... anyhow, let's see if this works before we get more orders from jlcpcb and if there maybe is some smart change that can be done too ... I was thinking maybe a footprint for the 3A DCDC board to bring 5V to SBC ... also maybe 3V3 pin on the serial header too ... and maybe some gpio from the sbc to some relay tu turn external something on/off ?! ... tbh I made this mostly to quickly test jlcpcb than I really give enough thought in the board itself .... now after I had some time to think about it I'm getting ideas but wanna see if this barebone thing works or not before I start adding stuff (and seeing if the jlcpcb works for me or not as I need a rather important project to design and if this works ok I'll use jlcpcb to do it, but if not I need to look elsewhere and design house dictate what parts I'll be using so...)

arhi

@Dougal1957 btw, just remembered I didn't export from kicad, I imported kicad project to online easyeda and ordered fromt there

https://easyeda.com/arhi.smece/duet2sb

I think you should be able to see it

btw, when you generate placement from easyeda the preview in jlcpcb show that U2 is rotated 180 degrees wrong. I let it go like that and then sent email to their support about it so they turned it properly. Then they explained that I should edit the placement file (it's text, comma separated) and rotate part myself till preview show it ok - for future projects

@deadwood83 i would order boards for Europe because i will make a new PCB order too! Is the EasyEDA file up to date?

arhi

@PCR that easyeda is what I ordered. it is not tested yet (boards shipped today so ..) and I have ideas for improvement but not put any on the paper yet (waiting for these boards to be tested first) so yes it is up2date

PCR

ah ok. you already orderd it I just see that the Boards from @deadwood83 still have R1 and R2 in place in the easyeda files

Dougal1957

@arhi Fair enough

@smoki3 said in Duet 2 Ethernet and SBC:

Any news about a firmware fix for SBC and Duex5?

Sorry, no news yet. Once I finish the PanelDueFirmware 3.2 release (hopefully the coming week) I will get back to investigating the problem with DueX attached. Though since I last tested a lot has happened in the firmware. Have you tested RRF 3.2-beta1? Is it still broken?

smoki3

@wilriker

Testet today again with latest official release.

Still not able to home all axis at once (simple G28 command). The printer hang forever.
All axis are homes with stall detection.

Firmware flashing now seams to work well.

Sometimes homing is working now. I will try a print later

30.9.2020, 08:31:36	Warning: Lost connection to Duet (Timeout while waiting for transfer ready pin)

This is what I get when trying to start a print. It happens when the first move is requested

Tried it a few times. Always the same issue

wilriker

@smoki3 Thanks for reporting back the current state. I hope to get back to this sooner than later but I need to rearrange my hardware chaos on my desk.

arhi

arrived ... few days over 2 weeks, looks like I'm going to be using this jlcpcbp in future I'm satisfied with the results. @oliof one packed for you will be sent tomorrow so you can test, my hand is still in bad shape so not sure I'll be able to solder the headers these days so you might get to test it before me

paneldue connector is in the way so is the probe connector, they are high so the normal headers won't work if I do not remove those two connectors... this is bad, but for the test it will be ok as I do not need the paneldue with sbc and I can live without probing for the test but next iteration should solve this, for now I'll just use the "Double length" pinheaders so I can test it.

The board is also covering the piece of the expansion port but since duet+sbc don't work with duex if I understood correctly that;s also not a big deal but I might make a cutout for that too

arhi

got the 7yo to help me solder this, one handed soldering is a ^#^#%*)^#@ .. 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 ..

good thing is with these long headers I can easily attach probes to sniff signals if required

arhi

so far, not working

Clearly I need to remove networking stuff from the config but I doubt that's a too big of a deal, dunno if I need to add something for the SBC ?

I didn't edit any config, only thing I did is increase SPI buffer to 8k on the pi

will hook up the scope in a bit

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

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

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