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?

This post is deleted!

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.

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)

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?

started simulation (2%)

@bearer said in Duet 2 Ethernet and SBC:

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.
