Or not!? For 3000rpm I need 12MHz with the 1000ppr encoder.

3000 RPM with a 1000 PPR encoder (4000 quadrature counts/rev) is a 200 KHz count rate

(50 RPS * 4000)

Ohh, yes, I calculated in minutes. Anyway, I can use the ethernet type with a laptop as well.

You should be aware that laptops in general do not make good LinuxCNC hosts

This is because they very often have power management hardware/software that cannot be disabled
and that causes large latencies. Some Laptops may be OK or at least OK until you change the backlight brightness
or change from line to battery power etc etc
