hi,
(1) i am just trying the cnc driver. i setup port 8 (where my arduino is connected) but the software is telling me "unable to open port (win error code: 2)".
(2) i wired my arduino the way it says in _init.pde what is strange is that the stepper motors all go on "wake up" and get hot after a while. maybe i am an idiot but in the _init.pde it says pins 14-19 correspond to analog 0-5 so i connected pin 18 to A4 ( where it says analog in). i guess this is bullshit - can you tell me where the pins 14-19 are? i am sorry for asking stupid questions but i maybe an idiot 
please help!
