dX = dA ( red belt ) dY = -dA + dB ( blue )

Now it seems right, but the kinematic is a mix of H-Bot and CoreXY.
dX = dA ( red belt ) dY = -dA + dB ( blue )
I don't know if it's worthadding extra length to the blue belt and get more stretch/ringing there, just to fight extruder tilt. ( which is neglectible when using linear rails and carriers)
edit: I just saw that both belts are equal length, so forget my above comment. It's even worse: both belts are extra long which is a big trade off IMHO.
Trying to figure out a belt system that has a cartesian configuration (unlike the h-bot and coreXY) so that there's no unbalanced forces being applied where you don't want them to (for example, rotational forces), but without having the motors move like in a traditional cartesian configurationQuote

What problem is being solved here?

Do these "unbalanced forces" cause problems?
With careful positioning of pulleys, a single-level corexy mechanism could be made free of "unbalanced forces", I think.
OTOH< if you want to try to come up with a new belt layout...
