Which controller board is best to use with LinuxCNC? I have a 3-axis router. DM542 stepper drivers and Nema 23HS9430B motors

If you can justify it, Mesa 7i96S.
For very cheap use an old PC with a parallel port, or a new-ish PC with a parallel port add on card.
Both versions are extremely reliable, proven by many machines in daily use.
Depending on requirements, parallel port might limit the maximum speed, still very usable always.
