Sorry, the green light on the board remains on throughout, comms or no comms.
The blue light on the board is on only whilst connected to the software.
This is a UC300ETH, btw, not an AXBB.

Thanks. I have just re-RTFM and found:
The green LED in the RJ45 connector is the 'Link' Led which lights when there is an active
connection to the computer or switch/router. If the green LED is off when the LAN cable is
connected to the computer and the AXBB-E board is powered then there is a physical
connection problem, the cable might be broken or has the wrong pinout.
The orange LED is the 'Activity' LED which lights when packets being received or
transmitted by the device.
And the green light goes off on mine. My parcel is due before 11am tomorrow so I will have another look as I can't say I have seen an orange light BUT probably not looked at it when it has connencted. I have also now got another spare hub to try.Last edited by ngwagwa; 23-04-2020 at 09:18 PM.

So out of stepper I have 6 wires 2 pairs each with a resistance of 2.4 and two purple wires with a resistance 0.4. The 2 pairs are connected to the drivers and i have (so far) been unable to trace the purple inside the cabinet but they are not connected together and there is no connection between the 2 puple and the other 2 pairs.

That's the configuration on my X Axis (I found out thanks to JAZZNC and Doddy) it was originally wired A+ to COM and B+ to COM so we changed it as per your diagram.
Thinking the Y and Z axis would be the same I was examining the wires on the Z axis (typo earlier) but all I could find were two pairs with a resistance of 2.4 and the 2 purple with a resistance of 0.4,

Many thanks to everyone especially Doddy and JAZZCNC for all the assistance given and my Denford Router is now much improved with a new 65V power supply, digital drivers, AXBB motion controller with UCCNC at the front end. Along the way I have been introduced and educated in many of the intricacies of CNC control that prior to this were black magic. I am now cutting metal and have only one more piece of the black art to come to grips with which I have posted in the UCCNC section of the Machine Control Software section.
