    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.

    I'm thinking about servos too. I saw This Old Tony's video where he uses Leadshine servos and it makes it clear to me the tuning software is just as important an aspect as the hardware. https://www.youtube.com/watch?v=tiVWBOBUlaA&t=1485s

    However those leadshine ones are still kind of pricy if you can even find the current models on a Chinese market place. I costed them up as about 200 for the driver (www.shop.cncdrive.com/index.php?categoryID=168) and 300 for the motor (Polish website I can't even find again).

    However I've heard many also recommend Delta servos and they seem to be priced somewhere between Leadshine and Lichuan and their software website also mentions some advanced software tuning such as automatic resonance detection and notch filtering.

    Someone else on another site mentioned the Deltas and said they were excellent so it may be the way I go. They are only fractionally more than the Lichaun ones from what I have seen.
