Hello guys, I need help, the autorouter doesnt work, my board is not demanding (a total of 249 connections). I used mostly JLC components, I have no copper zones, no solid areas. I also tried to remove the mounting holes, I have no errors in the DRC. I use a local autorouter, I tried other connectors but nothing helps, manual connection does not smell much to me. What is recommended? nejdze.jpg

Tgere is not enough information in your screenshot.

Can you make your project public?

Remove the duplicate board outline and the Auto-Router will work just fine.

Regards.

Hey! I think I've got it! You have 2 board outlines on top of each other and it seems to bug the autorouter.
Enable only the Board outline layer, then select all over the outline, you will see 8 selected objects. Hit delete, you'll delete the unneeded outline and the other one won't be deleted because it's locked. Then you can do the autorouting.

Also, some autorouter settings may need to be altered.
One thing that helps the tool a lot is to not allow it to route the GND net, add a GND plane on top and bottom where you can, the add GND stitching vias.

Also the routing settings seem a bit too crazy:

Track width and clearance could be lowered, maybe you have some special nets where the track width needs to be bigger or smaller. You can set that up too.

Here's a part of what it routed:

Happy routing!
