Hi Juanjo, Once you get into a machine with servos, limit switches and a servo'ed spindle the size of the machine doesn't make much difference. Hopefully, your servo amps expect plus and minus 10 V as a drive signal. I don't have specifics but there are people running large machines on emc2. As per previous discussions on this list if you have backlash on your ballscrews then tuning the servo's is more difficult than when the encoders are on the ballscrew.
