HI David,
One last ditch effort with the NVEM.. Getting a crossover Ethernet cable tomorrow. If that doesn't do anything, then it's the 400ETH. Since this is my 1st CNC venture, I believe that the 10 inputs should suffice. I like the 12 volt input since I have the power supply already in the electronics bay. I found this (
https://www.ebay.com/itm/5-Axis-CNC-...53.m2749.l2649) breakout board on ebay which should do the trick for me to start. There are others, but from China which will take another month to get here.
I did look at the ESS, but liked the versatility of the 300/400 better. Both solutions are supporting the MACH4, but that doesn't appear to be as popular as the MACH3.
In any case, I'll let you know how things turnout.
Regards Jeff
