Hi All: I have a wide outdoor deck stair to build with a platform. I can use 2x12 PT 8' long that will fit nicely on my 4x8 PRS Bot. I will be cutting between 8 and 10 stringers, and thought the job would be easy to do with the bot over conventional circular saw and handsaw technique. I have Aspire software, and could use some good pointers on creating the file. Any and all advise is greatly appreciated. Thanks Joe
