router bits are advertised to allow you to set up the first bit and all others will automatically adjust to make the correct parts. That didn't work for me. Might be my mistake but every bit should have been erased when I used it. An expensive bit set would have been worth the price if only the first bit needed tuning, but that wasn't the case for me. I even used their tuning tool and had to run several test patterns and tweak after each one. Trial and error was able to set it up correctly. The bits cut really well and after a lot of trial and error and time to set up resulted in a clean lid with the cabinet door panel.
