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!

The MBP Network page, with the USB/Ethernet Adapter identified itself as ‘AX88x72A’ and I selected the ‘Configure IPv4:” to “Manually’
IP address 192.168.2.2 and Subnet Mask to ‘255.255.255.0’
The M552 P192 168.2.3 S1 line entered via the use of the MBP TextEdit app in the config.g file points to the solution for the successful connection! Remember to Save It to the SD Card!
Learnt a lot – know how little I know @kbjpick
the result of the ping 192.168.2.3 command. Even to my uneducated eye it appears something is awry? Ken
