Editing Plot Points

The plotpoints x and y need to be modified in order to output the correct size.   

Import the 1"x1" inch box into Stonecut. 1by1square.eps
Press Ctrl + Shift + P in StoneCut tand the Driver Editor will open.  
You can find it as "%plotpointx%" and "%plotpointy%", under the "Name" column, seen on the right hand side of the driver editor.    Change the values to 0.1 and click File > Save (CTRL + S command to save) and test it again.  
Send the 1"x1" box to the cutter and measure it.  Your cutter is now dialed in.
