Restart DuetControlServer (SBC)
-
My understanding is that the DCS will be waiting for the Duet to show up and connect when it becomes available.
What firmware versions?
-
I'm running the latest 3.2.2 and SBC fully updated. With the pi already running for a while, I've turned on the printer and even after 10 minutes it still has status of Off and of course the DWC won't send any messages in that state.
-
Can you enable some additional logging?

Here's when starting the DCS debug with Duet 3 off:

and retesting it's working properly. After doing a reboot of pi it's back to doing the same thing. -
Double check your cable between pi and duet.
Can you post your config.g?

Do you have anything in daemon.g?

Yes I do.

Just as an FYI I renamed daemon.g and tried it that way and it didn't work.
-
Was it working before at any point? Did anything recently change?
Could you try a fresh image of Duet pi and updating again?
https://pkg.duet3d.com/DuetPi-lite.zip
https://pkg.duet3d.com/DuetPi.zip
Can you check what firmware is installed on the Duet via USB?
-
Reseated the ribbon cable...no difference.
No, it's never connected (duet status: Off) when the pi has been running before the Duet has power. Just to be clear: when duet is powered and I reboot the Pi or restart the duetcontrolservice it will connect.
Duet 3 firmware is 3.2.2 (read via usb)
Redid the DuetPi image to SD card (image verified). Had the duet off and booted the pi to go through the first time initialization. Turned the duet on and it connected. Turned the duet off and waited a little bit and turned it back on and it didn't connect. Turned off duet and rebooted Pi, turned on the duet and it connected.
It looks like it will do it the first time the pi is rebooted but not after that. Also did the apt upgrades after the above, also no change.
-
Is it possible that after the first time it waits to connect and then the duet is off that it doesn't check/wait again?
-
DSF does indeed wait for the Duet 3 to up and ready. In your case it looks like the might be dodgy connection between the Duet and the Pi which could cause the warnings from your log (all 0x00 or 0xFF could mean a timing issue on the TfrRdy pin).
Can you post the output of M122 when connected over USB to the Duet (with the Pi attached)?
-
With Pi attached and running and Duet off.

If you get that message it basically means that systemd will no longer restart the duetcontrolserver service.
The systemd documentation is a little tricky to follow but this message is generated if the service needs to be restarted more than a certain number of times over a period of time. In this case I think the defaults are 5 times in 10 seconds. I think this can happen if the Duet is turned off and the transfer ready pin floats high.
Given that the main purpose of the SBC is to talk to the Duet I'm not sure it really makes sense to disable the service in this way. If you are happy making changes to the rPi config files (worse case you just reinstall everything), you can tell systemd not to disable a service in this situation by adding the following line:
StartLimitIntervalSec=0to the [unit] part of the service control file. In this case that file is:
/etc/systemd/system/multi-user.target.wants/duetcontrolserver.serviceif you modify to look like this:
[Unit] Description=Duet Control Server StartLimitIntervalSec=0 [Service] ExecStart=/opt/dsf/bin/DuetControlServer TimeoutStopSec=60 Restart=always Type=notify User=dsf Group=dsf UMask=0002 CapabilityBoundingSet=CAP_SYS_PTRACE CAP_DAC_READ_SEARCH CAP_SYS_TIME AmbientCapabilities=CAP_SYS_PTRACE CAP_DAC_READ_SEARCH CAP_SYS_TIME [Install] WantedBy=sysinit.targetThen the action that disables the service should be turned off. Note that after making the change you should run the following commands:
pi@duet3:~ $ sudo systemctl daemon-reload pi@duet3:~ $ sudo systemctl restart duetcontrolserverMay be a good idea to make a copy of the file before you edit it.
I've seen the service be disabled when updating firmware on the STM32/LPC port of RRF (that I look after). In that case flashing new firmware is different to the Duet and the firmware restart takes longer which can sometimes trigger systemd to disable the control server. Making the above change seems to fix that problem for me. It would be interesting to see if it helps with your problem.

@BeosDoc said in Restart DuetControlServer (SBC):
Reseated the ribbon cable...no difference.
Do you have another ribbon cable to test with or possibly make some jumper cables?
@gloomyandy said in Restart DuetControlServer (SBC):
StartLimitIntervalSec=0
I've asked christian to take a look at this. Regardless, the Duet and Pi should be making a connection so the retry shouldn't come into play. Seems like either a bad cable or damaged pins.

I don't have that file in /etc/systemd/system/multi-user.target.wants
I did find it in /etc/systemd/system/sysinit.target.wants/
Mine at that location is currently:
[Unit] Description=Duet Control Server [Service] ExecStart=/opt/dsf/bin/DuetControlServer TimeoutStopSec=15 Restart=always Type=notify User=dsf Group=dsf UMask=0002 CapabilityBoundingSet=CAP_SYS_PTRACE CAP_DAC_READ_SEARCH CAP_SYS_TIME AmbientCapabilities=CAP_SYS_PTRACE CAP_DAC_READ_SEARCH CAP_SYS_TIME [Install] WantedBy=sysinit.target
