Thanks for moving this post Iving,

I knew this was a silly question and its probly not even appropriate for this forum but as i'm in the early stages of getting all the stuff to build my own cnc machine i've got stepper motors on my mind, so when my friend who is organising a festival in portugal approched me about rigging up some sort of fire display the first thing that came to mind was gas torches controlled by stepper motors

i'm sure i could use mach3 to run some motors for some random affects but if i could get the steppers to move in time to the music i would be 'the man'
