I've been trying different drivers in your PiAlign software and have a question about Lo Cutoff with regards to port dimensions. When I enter different values for Lo Cut the port size does not change. Am I doing something wrong? Or is this normal?

I am building a PI Cornerhorn for my brother. He's been hounding me for the last few months to build him one. I promised him after the job hunt is over. Well I was finally offered a decent job, so no more excuses.

Thanks,
Jeff
