Stepperonline A6 - How to properly Tune them?

Hi there,
a friend convinced me to go the Ethercat way. I got A6-400W-Ethercat Servos.
I followed the "How to use A6 Servomotors Software" guide by OMC but after the "Auto-Tuning" my Servos or better to Say the Couplers are still movable by Hand. If i increase the gein when Tuning, it starts to play airhorn.

Could someone maybe advise me How to properly get started?

If it ain't broke, don't fix it.

You mean, that you didn`t tune your Servos at all?
In my world a Servo need to be tuned connected to the machine and the load it has to work with to work properly and performant.

I'd be wary of any auto-tuning software.

It might work, but could also be placebo.

Im in the same boat, going to need to tune my a6 servos soon. did you get the tuning software to work? I havnt messed with it much but I couldn't get my win10 desktop to talk to the servo drive. I will have to fire up my laptop, as my desktop now has win11. Im kinda hoping there is an easy way to send parameters to the drives through the linuxcnc computer through the ethercat. I will say I have messed with a Haas VF11 mill, and I was able to move its big y axis ball screw by hand a few degrees. I dont think you can really get rid of all the "mushyness" in a servo.
