Has anyone here got experience of tuning any of the AC Servos from China. I am considering getting some, specifically the Lichuan A4 type as per the pic below. I downloaded their software and eventually managed to get it loaded on an old XP computer (couldn't get to work on W10 even in compatibility) The software however looks to be just an easy means of setting parameters and there doesn't seem to be much in the way of tuning compatibility built in, in other words it is just a computerised method of enter parameters rather than using the drives buttons.

I am a bit wary of buying the drives/motors in case they are a nightmare to tune.
