The Anilim Motors I have used 10000ppr encoders with Tacho but single-ended. They connect to the rotor with a 1/4" shaft which screws into the end of the rotor, the encoder then clamps to the shaft fastened with a grub screw, they sit on little slotted spring steel upstands which fasten to the motor plate and allow it to be adjusted.
I've replaced the encoders with differential 2500ppr quadrature encoders but these came with 6mm hole so removed the pin and turned them down on lathe. Simple and easy upgrade.

No I believe you can only wire Limits in series which go to L+ and L-, the home switches go to the X0, Y0, Z0 inputs.
