Here are pictures of my latest case that uses the Ethernet SS. The ESS is really nice and it performs well with the G540. The G540 are awesome by them selves but the added features of the ESS make it even better. I have built a few now with 6 axis using a G540 and 2 G251. Other versions were 5 axis with a G251 and a separate connector for a VFD and one for the input and output pins.
