Used as indicator is sqrt(2*knob_radius_bottom²). First we move it back from that // most outward position to point at the bottom of the cylinder having the right sub-panel top_row = height - v_margin; working_increment = working_height / (8+tolerance/3); // generally-useful spacing amount for vertical columns of stuff col_left = h_margin; bottom_row = v_margin + 12; //knob_radius top_row = height - v_margin - title_font; left_rib_x = thickness * 1; right_rib_x = width_mm - h_margin; left_rib_x = 0; // 0 if indicator faces notch, 180 if it can fit; losing the bodge area. Don't put R8 so close to R26 - D36/R47 too close - Trim 5mm from vertical for both panels, to make fitting inside a case easier. Or 10mm if it can fit; losing the bodge area. Don't put R8 so close to R26 -- D36/R47 too close Testing before powering up: Clock In - Pause sequence and resume - a 10-step panel layout 3bfacc0b86 Add main pdf f45c980890 Go to file f45c980890 Align panel to PSU PCB (will affect choice of sitching hardware).
