I have two projects so far, and both have net classes defined. Quilter ignores them and does what it wants. The first time it was fine, but the second project would result in a fire. Is there a way to make sure it respects net classes and constraints? It is also disregarding the inner copper layers.

Thank you for your help.

Hi there,

Thanks for reaching out. Could you send me the URL of the job you are referring to at justin@quilter.ai so I can take a look? There are setup parameters that cover some net classes & constraints as well as ways to maintain inner copper layers. I’d be happy to give you some ways to improve your output on your board.

Thanks,

Justin - Quilter
