From the videos you posted for comparison, the BFF software handles better the 6DOF math.
As you can see the x-sim plugin, limits the motion of the opposite motors a little bit resulting in different angle, while you get the full range for all motors in BFF software to allows the combined surge and pitch motion to be correct.
So I think it has to do with the limiters in x-sim plugin.
"Perhaps the COG equation uses the Top Platform points instead the Base points for the calculations."
Or maybe the opposite. That's why the CoG is fixed.
In my opinion, the CoG should follow the DoF movements.
Is it logical for you?
Erasing all "gcenter" variables from the code doesn't correct this behavior. That's odd.
I think the COG should be recalculated every time based on the TOP platform location. Right now is calculated once at the start of the program using the BASE platform as reference.
It is hard task indeed, I'm not good in math either and thus the reason I could not get these equations fixed. I tried to get in contact with John years ago, but he didn't respond, I hope he is ok, I remember he had heart health issues.
dureiken: Hi there, it's really quiet here someone could help me for my 6 dof project ? thanks a lot

fimmy: How's the firmware going?

tronicgr: @fimmy I had to put it on hold to finalize the manufacturing of the new kickstarter controllers. I tested parts of it to ensure compliance with the new features and looks good so far. I'll get back to it soon for integration.

Theuns: Very nice design.I'm also busy with mine and changing it also to Linear Actuators with 220v Servo motors.I'm waiting for my new controllers from Thanos. If I may ask Do you have any Sketchup files of your design and willing to share it I Thanks Theuns

atayeu: Hey everyone! I'm reading up and gathering all of the intel I can find for my first motion platform. this is by far best information for creating one.

tmcnam: I must be crazy but I still can't find the blueprints to the platform by GA-Dawg. Any help would be appreciated. Thanks guys.

Trip Rodriguez: Sorry tmcnam, the shoutbox doesn't get much attention. Did you find the blueprints? They are at the VERY bottom of the extremely long first post. It says "attachments: 6DOF.zip
