"For delta printers the situation is similar. It is necessary to have grid points defined that can be filled covering the entirety of DELTA_PRINTABLE_RADIUS, but there should also be a ‘border’ of valid mesh points that lie just outside the printable radius. This ensures that every grid cell within the printable radius will have all four of its corners defined.

So however bed size and printable radius are defined, make sure that your mesh grid is defined so that a full circle of ‘extra’ mesh points lie outside of the printable radius."

I need help with the above statement. How to I define a mesh bigger then my printable radius??
I cant understand how to do what it says above -> All parameters are tied to printable radius. So how do I make mesh bigger than printable radius. I can make the mesh inset for UBL 0, but that only makes mesh size equal to printable radius, not bigger. So how I get those editable points outside print area??

Please help, must be something simple I dont understand. The borders of the print area need help


I understand a have to define larger mesh, but where?, How? Which parameter?
