This is my project. https://easyeda.com/boxxofrobots/New_Project-5828cd40bdf748ee98de0c00a8528b95 I cannot seem to get this to complete no matter what. It's a pretty simple board and yet, even after relocating the parts dozens of times and even making it 4 layers, the autorouter seems to get tied up at the same place - laying out traces for a user contributed part, IC1. Can anyone tell me what I am doing wrong, or is there something wrong with the part spec? It has a schematic symbol and footprint, but the router simply refuses to get past laying out the surrounding circuitry. Often it gets hung up running the same trace over and over.
