You _probably_ don't need to take the tachos to LinuxCNC.
Typically the tachos connect only to the servo drives to feed back velocity, and the analogue voltage input from the controller sends a velocity command based on position feedback from the glass scales.
The Leinien FM1 looks like a lovely little thing.
An all-in-one solution from Mesa would be:

But there might be cheaper options (for example 6i24 + 7i33TA) but the 7i97T ethernet option will work with just about any supported computer, including the Raspberry Pi.
Other options exist. EtherCAT, Pico PPMC for example.
One of the LinuxCNC developers lives in Münster, I think.
