Duet2 Wifi+Duex5 and SBC

@taconite My fault. I was mixing up RPi pin numbering schemes. I meant GPIO 25 which is physical pin 22. So that's actually correct on your end already.
Too tired right now for good ideas, sorry.
Re ground connection: it's totally sufficient to connect any one of the ground pins of RPi's GPIO header to ground of your PSU. While testing I even powered the Duet from one of the USB ports of the RPi. Worked fine. Only when I eventually applied 24V VIN to the Duet it was that I required this extra connection for stable communication.

@wilriker alright! Than get a good night of sleep
I would really appreciate if you could come back tomorrow with some fresh ideas
hahaMaybe with an idea how i could diagnose a possible error. To narrow it down why it is not connecting.
-
logging in via ssh to see why dcs isn't starting would be a a good start, see
systemctl status duetcontrolserver.serviceand/orjournalctl -xeu duetcontrolserver.servicefor details.To troubeshoot the spi stuff maybe search for "loopback" to see an old thread troubleshooting a faulty raspberry pi

Feb 05 17:24:04 duet3 DuetControlServer[4086]: [fatal] Could not connect to Duet (Timeout while waiting for transfer ready pin)
this suggest the trf_rdy pin isn't wired/working correctly.
(also please put three backticks (
```) over and under long text like that to preserve formatting next time, or use the code formatting button on the toolbar (between strikeout and link)) -
So I rechecked the wiring and the board itself - didn't find any issues. Reflashed the SBC firmware to the Duet and it seems that now I get a connection even though it is not really stable. BTW the Duex5 is not connected right now

I can reach it over the network and I uploaded a valid config but its not responsive at all
-
Can you provide a photo of the wiring between the Duet and the Pi?
-
Verify RRF and DSF versions are compatible, if they are, odds are the connection is the issue given the checksum/crc issues.
How is the common ground between the duet and sbc?
Have you tried lowering the SPI frequency? (Edit there is a json config file under /opt/dsf on the sbc
-
@bearer
I got DuetPI (With GUI form here):
https://duet3d.dozuki.com/Wiki/SBC_Setup_for_Duet_3
RRF is 3.2.0I will provide Pictures of the common ground and the wiring in a minute. (maybe I should increase the gauge of the common ground)
No I didn't change the SPI speed but I could try to
@dc42
EDIT: The black single cable is the common ground
-
The little pcb has a pad labeled gnd1, this also carries a common ground from the duet to the sbc?
and the shield is grounded at both ends? if the shield is the ground connection thats not optimal either, ground the shield at one end and use a conductor for signal ground
the cable also seems a bit long in the tooth, reducing the spi frequency might help if the length is the issue.
/opt/dsf/conf/config.confand reduce the"SpiFrequency": 8000000,to maybe 2mhz or even less -
Yes the GND1 of the little PCB from @deadwood83 has a connection to the GND of the Duet and the SBC
So what I did:
- Removed the Shield from one side
- connected the GND1 pin of the little PCB with an extra cable to the GND of the SBC
- reduced the spifrequency to 2 MHz.
--> same thing as before
What do you mean with "bit long in the tooth"
-
The Duet to Pi cable is way too long. Also, as it is a round cable, it will have higher capacitance and more crosstalk than a ribbon cable would. You should replace it by a short (150mm or less) ribbon cable.
-
Changed to a short ribbon cable - nothing changed - still "no header" fault message
-
maybe I should try the duetpi-lite?
-
@dc42 Sorry for bothering you again. Do you any other ideas?
-
Sorry for not getting back to you earlier. DuetPi-lite won't make a difference.
Can you please run
DuetControlServerfrom command-line with-l debugto usedebuglog level and post the output? Former output posted here did not contain enough information.Manuel
