Hi,
this is the link to the $2800 Mach4 Ethercat solution, it includes a Vital Systems Ethercat board, Mach4 license and 3 x 750W Ethercat servos for $2895:

To be honest I don't think this is the best Ethercat solution, I mean all you are doing is replacing a Step/Dir board like an ESS with a Vital Systems Ethercat board.
This link is more what I had in mind. Kingstar and Interval Zero have collaborated to prouduce a realtime core for a Windows machine which therefore requires no external board whatever.
This kit includes a refurbished PC (inc monitor), Mach4 license, RTX64 runtime license and three Ethercat 23 size closed loop steppers for $1958. Given the hardware content and the licence suite its probably
not bad value.

As you know I'm not a fan of closed loop steppers otherwise I would have considered this myself for my new build. Ethercat has advantages but for hobby machines its a wash....and therefore stuck with Step/Dir.
