Duet2 Wifi+Duex5 and SBC
-
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
Duet 3 6HC (v0.6) with RPi 4B on a custom Cartesian
with probably always latest firmware/DWC (incl. betas or self-compiled)

With what command line exacly? Sorry I am a bit of a noob with RPi and Shell

@taconite What I meant was a command-line shell, i.e. login via SSH or in case you have keyboard and screen connected to the RPi open a shell there (in UI look for Terminal or Shell). Basically the location where you also ran
systemctl status ...orjournalctl.Manuel

systemctl status ...orjournalctl.I guess we had a misunderstanding. I understood you that the command line needs to be in SSH or on the pi command itself. I was wondering about the command that I should issue

@taconite Sorry, I haven't been clear. So a more step-by-step instruction set.
First make sure to stop the duetcontrolserver service:sudo systemctl stop duetcontrolserverthen run DuetControlServer manually with debug logging enabled:
sudo su - dsf -c "/opt/dsf/bin/DuetControlServer -l debug"This will output everything directly to the console with logging in debug level.
-
This is the output

@taconite I never tested how good it works with the Wifi Module still present. In theory that should work but I only ever tested with a Duet 2 Ethernet with Ethernet module removed. So it's possible that there is an issue with that.

mh okay I thought I read in this topic ((https://forum.duet3d.com/topic/17203/duet-2-ethernet-and-sbc)) that s.o. made it work with the wifi module still present. BTW the LED of the wifi module is not flashing and I installed the duet wifi server fw that came with 3.2 before I moved to the SBC duet FW
