New bed test for wide area height map.

thingiverse

This is designed to let you fine-tune bed heights on a delta printer as it loops through the design. Make sure to test with plenty of perimeters for several passes. Scale down to fit your print area, which should be within a 200mm diameter. As specified in the attached OpenSCAD file: ma = 52; // This is the radius where petals deviate from. lobes = 9; // Number of petals lobrad = 45; function lr(a) = sin(a * lobes) * lobrad; // Changes radius to form petals function x(a) = (ma + lr(a)) * sin(a); function y(a) = (ma + lr(a)) * cos(a); points = [ for (a = [0 : 1 : 359]) [x(a), y(a)] ]; linear_extrude(height=2){difference(){offset(r=3){polygon(points);}} polygon(points);}
