Fresh start with linuxCNC and Ethercat

Hey !
I'm building a cnc mill with a german FS4GM epoxy granite gantry and a Spinogy X22 spindle. It's a small but rigid setup that I'd Iike to control with 400W servos, LinuxCNC and EtherCat.
Since I only ordered the mechanical parts+spindle, I still can avoid some problems (ie latency issues) by choosing the right things on the electronic/control/computer side. Hence this newbie message : 
What servo/drivers/computer/other things-I-still-don't-know-about would you go if you had to get them again ?

Cheers,
Flo

If you already have an extra PC, try using that.

It might need an ethernet card (or two)

LinuxCNC seems to run quite well on old PCs.

Set the CPU governor to performance and make sure you have enough RAM.

You want 0 possibility of any swapping to disk.

The FS4GM gantry with the Spinogy spindle should give you a very rigid platform. Since you’re still in the planning stage, it’s smart to think about the control side early.

Definitely an Intel network card for EtherCAT.
For one of the Qt interfaces I would not select the slowest computer around.
