Duet Software Framework

I have one of the new Duet 3 main boards connected to a raspberry pi v4. The boards seem to connect but when I try to update my config.g file an error Failed to create directory 0:/sys occurs. I attach the control server and we server log files and would be grateful for some help!

I'm not sure the files uploaded properly so am pasting the control server file.

please do ls -la /opt/dsf/sd and post?

@bearer thanks for your response. I'm attaching the output as requested plus ditto for the sys directory which for some reason shows the config.g file owned by root. I have also attached the config file which I am using to test with as the parser seems to complain about a duplicate P parameter which I haven't spotted so far.

Many thanks that worked

@pd also M550 should not be used at all right now. If you want to set the hostname, have a look here:

https://duet3d.dozuki.com/Wiki/SBC_Setup_for_Duet_3#Section_Changing_the_SBC_hostname

however it needs to be a valid network hostname so no spaces and no punctuation.

A Former User

As of 1.0.3.3 M550 controls the displayed name in DWC, but indeed it can only be set to the same name as the current hostname; however it defaults to "My Duet"

9/20/2019, 12:12:51 PM	M550 P"Duet3"
9/20/2019, 12:12:37 PM	M550 PDUET3
9/20/2019, 12:12:22 PM	M550 PTEST
Error: Machine name must consist of the same letters and digits as configured by the Linux hostname
9/20/2019, 12:12:14 PM	Connected to 10.10.0.195

T3P3Tony

@bearer yep, so best to leave it commented out until a future version when we can use DWC to set the hostname

pd

@T3P3Tony Yes apologies I should have mentioned that. The next error message I received said the name set by M550 had to be exactly the same as the host name. Is this a function of RRF 3 or the duet framework setup?

T3P3Tony

@pd its the way that printer names and hostnames are related right now. For now please comment out M550 and then set your hostname to whatever you want to be the network name and printer name.

@bearer weird - my does not it shows the hostname

After downloading the DuetPi.img to test, it comes up as "My Duet" with the hostname "duet3"

pi@duet3:/opt $ hostname
duet3

But the name in Duet Web Control does change to "duet3" after creating an empty config.g which seems odd that a value should have effectively two defaults at different stages of booting.

pi@duet3:/opt/dsf/sd/sys $ touch config.g

T3P3Tony

one is the default for the DWC application. the other is what DSF will set once it has booted.

A Former User

I get that, but I don't think many user will differentiate between having an empty config file and the defaults attached to DSF and a missing config file and the defaults attached to DWC.

T3P3Tony

@bearer well an empty config.g is not a state i would expect the system to be in except on initial setup. at which point, whatever is shown in DWC is not as important.
