Thanks andy for your recomendation. I'm reading about pico and mesa systems
for driving servo motors.
I'm curious about the 8i20 card. Does this card handle the PID
calculations? Or the card only reads the pwm signals from the mesa I/O
card?, so I need to use the HAL PID component and use it to

That card does hardly any calculations at all. It takes current and
phase angle information from EMC2/linuxCNC via a serial link.

Andy thanks for your explaination about the 8i20 card. So, this card used
with LinuxCNC and hostmot2 will work well to drive a servo for accurate
positioning. Right?
I saw that you wrote the difference between an AC brushless and DC brushed
motor if I'm not wrong. But the main doubt that I have

It _should_. I can't say for certain that it

Thank you Les and Robert for your answers. So, the best option is brushed
DC motors
Brushless are good too, if they come with drives. There are also
generic EMC2-compatible brushless drives from Pico and Mesa.

Hello to everybody on this list.
I've been working for almost two years with LinuxCNC software (the old EMC
hehe) and steppers driving an old Schaudt cam/lobe grinding machine. Now
it's time to improve the system and change the steppers for something with
more speed, specially for the Z axis.
i have tryed this also u can get close u will not get Servo
performance/position resolutions but u can get close.. hence why they
say servo like on VFDs spec sheets
and it does make a big diff what level of VFD you use also some are alot
better at this than others..
Yaskawa do some very
