Hi,
Sorry I'm a French girl and a very beginner 
So I have an eleksmill everythings works well .... with one exception
my X axe only move to the right ( X + ) when I press X- it moves to the right, when I press X + it moves to the right
I tried reverse X , it doesn't work, I tried to change $3 value on UGS, it doesn't work
Can someone help me please ?
Thank youuu
