I'm new to Mach3.  I have a Taig machine with Gecko 540.  My Mach3 read Gcode z1 and Zaxis travel 10 mm instead of 1mm.
It also does the same for X and Y axis.  What have I don't wrong?  I tried to use scale it 0.1 solved problem but when I tried to upload Gcode then the scale is off 1.00 again. 

Is the drive are set to microstep

If you done the calculation for Mach3 for microstep (1:10) and the driver are set to single step (1:1), you'll get that result.
