    Is there any way i would be
    @Thanos Is there anyway I would be able to purchase the necessary hardware to do my own conversion?

    Well now! Your spec sheet helped me out a whole lot. We have successfully controlled our vegafu setup dynamically!! Where did you source your Vegafu SMC from?

    Here's the hiccups we ran into, and it may be unique to our model but maybe it can help you out.
    -our source port had to be UDP 8410 otherwise it wouldn't respond.
    -our Vegafu had a static IP of 192.168.15.201:7408 (UDP)
    -by studying existing functionality, we built a test app that was rate limited to 50ms intervals with no more than a 2.7% delta


    Also, @Thanos that spec sheet has a 6DOF mode in it as well as 3DOF mode.

    Essentially what you want to do is is look at Example 1 in your spec sheet. check out the highlighted boxes.
    1301 -absolute time mode
    0001 - 6DOF mode ( if this is 0, it's in 3DOF mode)
    00000000 - This part is not highlighted, but it's the 4 hex values right before the first 0000c350 value. This is the time value. It's in milliseconds (converted to hex). In Absolute time mode, the vegafu goes to the position as fast as possible. You must constantly increment this as it's used for error checking. (i.e. if you sent it something with a time code of 50, and then it receives a time code of 25, it's going to ignore it)
    0000c350 - this is the position on the cylinder you want to move to. In this case, 25mm (based on the math in the paragraph above).

    If it wasn't clear, you're sending this via UDP network packets to the SMC.

    Is there any progress with Vegafu and possibly connecting it to Simtools? If not, what is the current best practice to control Dorna M1 that is compatible with Simtools?

    I am considering buying a chinese 3DOF simulator with Vegafu and it's likely to have Dorna setup too.

    Its more likely to use a AMC controller like this one connected to the Dorna servos: https://www.tindie.com/products/Tronicgr/amc-aasd15a-servo-motion-controller/

    ...than simtools supporting Vegafu...

    Do you have documentation for the Dorna EPS M1 drive? I have a 6DOF using the same Vegafu controller and EPS servo driver. Already bought Thanos controller but I am getting an error on one of my driver ops. E28. Anyone?

    Looks like motor stall issue. See recommend actions:

    Also did you set the M1 parameters as in the github? Make sure the DB25 cables to 44pin, are also correct.

    all this great stuff and using a G29? i hope you have an upgrade in the future. i have read or heard that a G29 makes you faster on the corner.
