Thanks for the quick response. I made a couple of test leads and measured a good 3.3V between the 3.3V, TWD, and gnd. However when I measured TWC, twice, it registered only 136mV. The Duex5 has been swapped and although much longer than the provided ribbon cable, I had an old 50 pin SCSI cable which I tried with the same negative result. So I assume that would point to a problem with the Duet-wifi card.
Thanks

I'm building a Railcore II 300ZL kit from ProjectR3d and when I issued the M115 command using Repetier Host, the Duex5 was not listed. After checking the cables multiple times, disconnecting everything, etc., I requested an RMA. Received the replacement board today and installed it with the original ribbon cable as a new one was not sent. Still not recognized! ProjectR3d is sending a new cable but in the meantime, is there something special about the supplied ribbon cable or is it just standard 40 pin ribbon cable. I'm also not confident this will fix the issue so does anyone have any other ideas?
thanks

Just to clarify, if you want to separate the printer network from your home network, the third number (octet) does not necessarily have to be different...it depends on the subnet mask. If using a 24 bit mask (255.255.255.0) then the third number must be different but the ip address ranges can be subdivided using the mask so that a 192.168.1.0 network can be divided by using more than 24 bits in the mask. So with a 25 bit mask (255.255.255.128), it becomes one network with an address range from 192.168.1.1 - 192.168.1.126 and another with a range from 192.168.1.129 - 192.168.1.254.
