Nice! The ferror might be larger when machining, though. Since we're talking about following error, one question has been puzzling me for some time. Say, we have some (pretty advanced) servo drives like Yaskawa or similar, with analog and step/dir input, so we can connect them either way (to 7i76 or 7i77). What is the best way to minimise ferror - use LinuxCNC pid with analog control or servo drive's internal pid with step/dir? I guess some cheaper Chinese servos can be tuned better with LinuxCNC, but what about more advanced servo drives like Sigma 5 or 7?
