3 for 3, nice!
New drives can also be controlled by step/dir and also have encoder outputs, and those can again be used in LinuxCNC.
And there are several boards from Mesa that can be used, not just 7i97, a lot of combos there so when you are ready to order stuff, ask here first as we have the Mesa Master with us here, always, in the form of PCW.

Yes.I assume the procedure is similar for newer drives if running analog?
Yes.I would tune the velocity/torque in the drive software, then tune position through Linuxcnc.
Yes.It looks like a few of the modern servo drives I've looked at have encoder outputs. Those will just run back into a Mesa card like the 7I97?

We have 3 phase power in houses, always, rated at 3x380V +-10% and can pull 16A at home from any plug, 32A in workshops/garages.
Lately the local provider started complaining if we pull over 15KW over long duration's, i do not blame them, we have 100A at our disposal.
To spite Americans (since i still refuse to go there despite being granted a Green Card 17 years ago), we can charge a Tesla at home with 22KW on any socket around the house, 60KW if we push it!
And that is with no permissions or requests or installing superchargers!
