@kbjpick hmm, yes, the ping response shows no connection. And you hadn’t turned off the Duet, so it’s IP address is still 192.168.2.3?

Do you have a spare Ethernet hub you can cable between the Duet and Mac? It’s possible the auto negotiation isn’t working between the two, and even a simple hub can force the right speed.

Ian Exposing all my ignorance here I know but, not sure what an ethernet Hub is? Google suggests one of these "TP-Link TL-SG105S 5-Port Desktop Gigabit Ethernet Switch/Hub, Ethernet Splitter, Plug & Play, no configuration required,' so have ordered it on Prime for delivery tomorrow. If this is not what you meant, please advise and I will order one. Ken

5-Port Desktop Gigabit Ethernet Switch

That should do it.

droftarts

@kbjpick have you checked the Mac can connect to your normal network, to test the adapter? Unplug the Ethernet cable from the Duet, and plug it into your network router. Then change the nerork settings for it from manual to dhcp and see if it assigned an IP address.

That hub looks fine, though I can’t guarantee it will resolve the problem.

Today's report. 5-Port Desktop Gigabit Ethernet Switch arrived albeit later than promised, and whilst working, it makes no difference to the communication between the Duet and the Mac, in that sending the command of ping 192.168.2.3 reports no response. I confirmed pre and post this activity that the address of the Duet WAS 192.168.2.3. I also connected the Mac to the router; changed the network settings from manual to DCHP and confirmed an IP address WAS assigned.

Following suggestion that .."next thing is to show a directory listing of the SD card" please see image of my Card in juxtaposition to the example provided - a simple observation is that there appears to be less files than the example?

Does the above provide any avenues for further investigation? Is it possible that whilst much of the Duet board is working, that the Ethernet 'module' is faulty? I have spent more time in connecting to a machine than the time taken to build it, but, I continue to welcome and appreciate your support in this. Ken

should really be an address in the same range as the duet if that is the ethernet connection intended to be dedicated to the Duet.

IP address 192.168.2.2
Netmask 255.255.255.0

(also please try to segment the different things you want to show, a jigsaw of windows is hard to follow)

droftarts

@bearer I think that was to show that the wired gigabit adapter worked correctly.

@kbjpick I'm sorry this isn't working correctly, I'm not sure exactly why it is not. Do you get any lights on the Duet Ethernet port when it's connected to the Mac?

As you can access the SD card, can you edit the config.g (in Text Edit is fine), change the network section to the following (change M552 line and add M553):

; Network
M552 P192.168.2.3 S1                           ; enable network and acquire dynamic address via DHCP
M553 P255.255.255.0                            ; subnet mask
M586 P0 S1                                     ; enable HTTP
M586 P1 S0                                     ; disable FTP
M586 P2 S0                                     ; disable Telnet

Then, at least, you won't have to change the IP address of the Duet every time. I don't think the addition of the M553 subnet mask is important, but you could try it out, and see if the Mac will connect with this set (after changing the Mac's IP address back to 192.168.2.2, of course).

M552 P192.168.2.3 S1 ; IP address

Except your Mac is using address 192.168.1.103

So change your Duet address to 192.168.1.3

kbjpick

@Phaedrux Forgive my naive question, but where do you see the MBP address is 192.168.1.103?

Phaedrux

In your image here

I typoed 104 to 103 though, sorry about that. But that's not really the important number anyway. It's the that the subnet needs to match.

192.168.1 versus 192.168.2

@kbjpick If the orange light on the Ethernet socket on the Duet is on, and the green one is flashing, I think the Ethernet module is working correctly. The Duet seems to be able to communicate with it, so I don't think it's faulty, and this is still most likely a configuration issue, or a hardware incompatibility.

Regarding your config.g. With the above, you said that, when you connect via USB, it's still reporting that the IP address is 192.168.1.14? There's nothing in the above config that specifies that, so it can't be using this config. Can you put the SD card from the Duet back in your Mac and check if you have two config.g files now? Macs often hide the file type (the bit after the '.', eg .txt) and I think it may have saved it as 'config.g.txt' (Text Edit does this if you change the formatting). You can show the file type by going, when in the Finder, to the menu top left of your screen and select Finder > Preferences (opens Finder Preferences) Advanced > Show all filename extensions, and make sure this option is ticked.

The other alternative is that you edited the config.g.bak backup file, but usually the SD card doesn't have this on it as shipped, and there's only a .bak file once you've edited config.g in Duet Web Control (DWC).

Once you have sorted that out, your config above should be okay, except remove these two lines from the end of the networking section:

M554 P192.168.1.255 ; Gateway
M553 P255.255.255.0 ; Netmask

If you have demounted the Duet and it's close enough to you router, perhaps you could plug it in and try connecting, as per instructions here: https://duet3d.dozuki.com/Guide/1.)+Getting+Connected+to+your+Duet/7#s20

It also occurs to me that you probably should have been disabling networking (M552 S0) before changing the IP address in the serial terminal connected to the Duet. Sorry if it's as simple as that!

192.168.1.# is what we're trying NOT to use for the Gigabit adaptor! That image was just to show that it did work with his existing network. The Gigabit adaptor and the Duet need to be in the 192.168.2.# range, for a direct point-to-point Ethernet connection, separate from his existing network.

@droftarts Ah! In that case, just ignore me.

With invaluable assistance from this Forum, in particular @droftarts for which many thanks – I finally have a communication established between my MBP and the Workbee Duet board! Still some way to go in setting it up and calibrating it but…!

I selected Ethernet as the connection method, in belief that with suspect WIFI availability in my garden located workshop, the use of a direct cabled connection would be more robust. However, the 2017 MBP lacks a direct Ethernet port, so I elected to use an USB to Ethernet Fast Ethernet connector. The initial issue was a compounding of my ignorance of the MBP Network Address system and poorly worded instructions (IMHO), together with an uncertainty whether the connections, both USB and Ethernet were working as intended or the Duet board was faulty i.e. when it doesn’t behave per the written instruction – which element is at fault -me, or the ‘bits’?

Notwithstanding, over the next week and with the help of the Forum as above, progress was made in educating me as to the mysteries of Network Addresses. The breakthrough was in discovering how to configure the address for the Ethernet adapter AND finding how to edit the as-delivered SD card config.g file. My son-in-law and a Windows machine provided an easier way to configure the Duet SD card config.g file and then I was able to connect the MBP to prove that either of the computers would jog the Workbee.

@droftarts suggested I post the config.g file which whilst no doubt containing some redundant lines/instructions, DOES work for me and may prove of assistance to those of a similar level of inexperience as myself!
