App updates, notes from the cut-and-print wall, and the things worth making.
100 mm at a 10 mm target = 11 fingers of 9.09 mm; the lid play carries a source (boxes.py's 0.05 ร T) โ and the test box before the good sheet.
Learn ๐ชLinks that bend by twisting: wยทcos ฮธ + Tยทsin ฮธ each, 23 links for a 90ยฐ bend in 3 mm sheet โ and the test strip before the panel.

Learn ๐ชClean bed, level plate, the right squish, a slower pass, dry filament โ five words and the print starts telling the truth.
Safety ๐ชChlorine fumes, cyanide fumes, resin fumes โ the materials that never go under the beam, and the E = Wยท(p/100)ยทN/v rule that shows fire first.
Learn ๐ชThe beam takes K/2 from each edge; ten squares measured at 198.4 mm give a 0.16 mm kerf โ and the printed gauge picks the clearance.
Learn ๐ช0.1 mm = 254 DPI, the BT.601 luma weights, four dither kernels by name, and the presets that admit they're estimates.
Learn ๐ชAn ID card is the ruler (85.60 ร 53.98 mm); four corners build the map; the photo's error is named in plain words.
