I am sorry but I will require this ticket to be more descriptive as I have no idea what this is supposed to achieve

I was wondering if this feature is really needed for cartesian printers? I thought that the belts are tentioned by the two blocks in the back. Maybe I misunderstood the CAD drawing.

In any configuration each belt has a tip that goes into a tensioning block and another tip that is held statically to the carriage. In CoreXY systems one of the tips is held by the block in the back and the other tip is held in the front. In Carterian systems the static tip is held by that groove and the other tip by the block

Having 2 tensioner blocks in a single belt would be redundant at best

Did I make it clearer? If you have any doubt you can reach out on discord

Understood.
