Hello ! I engaged CNC not so long and faced with the fact that the program provides a signal format step / dir, and I does not found that I needed for my controller, but it is for arduino mega 2560 mach3を使ってみた - 北の国から電子工作（仮） Can I change the code for arduino UNO?
I am a novice, it is difficult for me
