Recurring 4k7 (hoihu) errors, by impact

  1. 1On a real RP2040 board, six supply symbols stood in one column with a +1V1 stem running along a +3V3 stem, which read like a short. The in-app agent answered that fixing it needs symbol moves this run does not allow, and tried nothing. The fix changes both the drawing logic and what the agent is told about automatic symbols.ECAD · Agent failure · 1 report74
  2. 2The board tool wrote pick-and-place rotations in its own footprint frame while JLCPCB counts rotation from its own library footprint, so for SOIC-8, DFN, SOT-23 and WS2812B pin 1 sits in a different corner and JLCPCB engineers hand-corrected every such part.ECAD · Agent failure · 1 report74
  3. 34k7 schematic Issues list had 40 of 42 entries on spiral2 about how wires were drawn. Drawing findings now drop out of the Issues list and counts so the agent and the user see what is wrong with the circuit.ECAD · Agent failure · 1 report66
  4. 4JLCPCB could not place two SMD electrolytics: pads were chip-style strips as tall as the can, and one part was a 6.3 mm can on pads for an 8 mm one, and the stock check had flagged both by package name but similar-looking names made it easy to dismiss.ECAD · Agent failure · 1 report66
  5. 5Two empty schematic sheets took a page each, and nothing could delete them. On Oct 27 the in-app agent moved everything back to Main and asked the user to remove the sheets in the app, which could not do it either.ECAD · Agent failure · 1 report66
