Sorry for the English, I'm Brazilian and I don't speak almost anything. I have a problem that I don't know how to solve, I'm new to GRBL and my problem is the following. The program recognizes the machine, I give the + command on the Y and it moves, I give the - command on the Y and it moves in the same direction as the +, I reversed the X/Y cables and the same thing happens but with the Y, no I know what to do. I use Arduino nano + Laseraxecncc.mini
