I see there that only RepRapFirmware supported boards (Duet,?) can make use of it. What's the point because Duet already has a web interface. I don't really get it. Can this be used with SBASE? Will we be able to use it for Arduino Mega and the likes? That is the plan?

If you do the math you find out that the risk is very small. Most users disable enstops after homing anyways.
I wonder if this is something to be really concerned about in a big way.

for the z axis to get more resolution you could rap the string around a few times like the core xz approach of Nicholas

It can be tough to print teeth that match GT2 belt teeth because of the fine detail/small spacing. I designed this belt clamp that uses the belt's own teeth to secure the belt, simply by folding the belt back on itself. It is very easy to print because you don't need to print any fine detail. With this design, even if you pull the belt so tight that the center peg breaks, the belt will remain in place.
The youmagine page has designs for single and double clamps that mount horizontally and vertically:
GT2 belt clamps
It would be pretty easy exercise to modify the design to allow it to both adjust tension and clamp the belt tightly.

@Dalius98: I am doing nothing new here but re-interpretting the classic two-stage (two-planes?) Core XY arrangement. Smartrap CoreXY also uses exactly this and Wild River 240 before them and countless others. The illusion is due to the orthogonal view in my CAD. Unless there is something all these printers miss I don't think there is anything different in my setup. All that matters in this case is that the belt segments that go from corners towards the Y carriage must be parallel by all means. This avoids the issue you are linking.

The pin doesn't need to be fixed at all- once the belt is under tension, it won't go anywhere. You do need to make sure that the slots for the belt (in front of the pins) just allows the 2 layers of interdigitated belt to fit. That is how the belt is prevented from slipping. I used a slot width of 2.2 mm based on the dimensions of GT2 belt, and it fits tightly and will not slip, period.

Will you be sliding the motor mounts to tension the belts?

Couldn't you tension the belts the same way as you've sketched, but by pushing them towards the center of the printer? There has to be some leftover space to do so... And you could use a smooth idler... Or why not use a toothed idler and just tension them like you wanted?
