Hi, I'm currently using mach3 to control my 3-axis CNC machine and the spindoll is controlled appart, I use it to frequently drill some PCB boards. Everything goes well except for one thing: Sometimes I need to stop the machine in the middle of the work for some issues but when I do that the z-axis stops down, I need to find a way to tell the mach3 to always stop up so I can replace a broken tool for example.

I respond myself, I just didn't configure well the z-safe setup.
