Hello,
i had to split my Project in two PCBs. Both Boards get connected via the 12p Header. The Circuit is not fully complete but i wanted to rout it to check the estimated pricing via the Gerber File.
When i start the auto Router it only routs one PCB.
What is wrong with the Boards?
Many thanks in advance!
