Sanitycheck my plan: ethercat + stepperonline A6

Update:
I've got a draft electronics panel with all the ethercat stuff working with linuxCNC, including the servos which i'm able to jog around, which is a great start! it'll be a while until they are mounted physically on the machine, but i want to get started better understanding the process of tuning them, specially since i'm basically blocked from continuing with the physical part of the build until a few more things arrive.
I was able to get the stepperonline software running on a windows 10 vm within qemu and perform the inertia autotune part( which i'll obviously have to do again when they are really mounted ). I understand after that comes a manual part in which you tune the gain along with other stuff, basically testing movements and see what minimizes the error, but i've no idea about how this is done concretely, like what steps in which pieces of software, and specially how it is done for the 2 motors that share an axis.

How did you manage to connect to the drives?I’ve installed the software, but I can’t get a connection

I didn't do anything too special compared with this guide  other than selecting "USB_CDC" for communication and then scanning on the available "Serial Port" options until the driver showed up. If yours doesn't, try a different cable.

Do you use a USB to RS232 adapter cable? Not all of them work properly. This one does

According to the description, a standard USB cable is required.
After installing the software, the USB-to-serial driver apparently needs to be installed.
There are several in the program folder, but which one is the correct one?

Forget my post about the adapter cable. I mixed up the servo types.

You need a USB-C cable with data transfer. Some can only charge.

I know the kind of driver you're talking about, but this was literally a freshly installed windows 10, and all i did was install the stepperonline software and forward the usb device to it and was able to find it in the scanner. i didn't install anything else.
