	To address the proper piercing issue, [[Vann Miller]] has written a correction script. This script does 3 things. First, it takes out the z values generated by the [[DXF to G-code Converter]] (not needed in a 2-axis motion system at hand). Second, it starts a pierce by moving towards the center of a hole. Third, it rotates the torch around a small radius (.05") during preheating. The number of rotations is currently 8.
