If you are still having ethernet issues this video shows you how to determine if the CNCPC ethernet port is working and then, if it is communicating with the Acorn CNC Controller. You can validate that your CNC PC's network address of 10.168.41.1 is configured properly. As well as to use Windows PING to test it and test communications with Acorn's fixed IP address of 10.168.41.2
If you are having problems, post which IP address (CNC PC or ACORN) you could not Ping in your post.
As always, BE SURE to follow Centroid's Windows 10 Setup video. Remember this is a motion controlling PC, not a gaming PC or to play Angry Birds on!

be sure to have windows setup properly.. https://centroidcncforum.com/viewtopic. ... s+10#p8872
no USB Ethernet adapters, use a shielded Ethernet cable, no anti virus software installed.
The Windows Ping Test is a great test to confirm basic Ethernet connection from the CNCPC to the
Centroid CNC controller card. It helps you quickly determine if there are any “big” connections issues between the CNCPC and the controller card. It however is not a definitive test. Just because the ping test reports good results does not mean the CNC system is free of communication errors. The ping test really just confirms at that moment that the two Ethernet ports are connected and communicating. CNCPC Communication errors can and do sometimes only occur when noise (electromagnetic energy) is introduced into the system or some software decides to interrupt the communication for some reason.
See Tech Bulletin #270 for detailed information on how to solve communication errors. https://www.centroidcnc.com/dealersuppo ... ds/270.pdf
