To clone: submodules avoid non-circular holes in footprints whenever possible; some fabs charge more for ovals - make power connection traces larger; MK uses .6mm this means from the side (HP hole_dist_side = hp_mm(1.5); // Hole for setscrew // Make sure bottom ends at z=0 KnobMajorRadius+RingWidth) * 3, 20], center=true); } // draw panel, subtract holes // v_wall(h=4, l=height-rail_clearance*2-thickness); // top point? // Pain Train alt tag, Alice Grove bigger img 4d8e233e93 Add CV in to pause the sequence. Probably can't do, or impractical: CV-controlled clock. Presumably the CV in to pause the clock.
