delta printers / negative offsets

[tmbdev]

It's hard to generate G-code for delta printers with the current system. It would be nice to at least have the option of having negative offsets to fit a square test pattern into the center of a delta printer.

Ideal, of course, would be adding a circular/polar coordinate pattern for round print beds, with flow rates corresponding to different angles and temperatures corresponding to different radii.

yes it would be really handy, for now I'm using standard flow values ​​taken from the internet for the hotend I have on my delta, but I'd like to have more accurate and precise ones for each type of filament I use

+1, it'd be great to have that.
