Recommended feeds for PCB tools

Posted on March 16, 2018.

Addressing the questions about what feeds to use when milling the boards, we decided to throw together a little table with feed recommendations for the tools Cirqoid uses to mill and drill PCB laminate. These are the values that worked well for us. Happy milling!
