	~~The gcode files from the dxf2gcode toolchain alone will not be effective for the torch table~~

	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, but '''one should be able to modify this'''.

	To run this correction script, download the coverter file - make it executable, and run it from command line. Here's Version 0.22 of vanngcode.php - [http://openpario.mime.oregonstate.edu/documents/1236] . This works based on correct understanding of G2 syntax. It also ignores arcs, and only pierces circles on their interior.

	~~php vanngcode.php <file.ngc>~~

	~~Where <file.ngc> is the name of the ngc file. The converter will eliminate Z coords and add preheating/piercing to circles.~~

	~~Also, now the interior offset can be set via the command line, e.g:~~

	~~php vanngcode.php input.ngc 0.3~~

	... would offset 0.3 inches into the circle before piercing. The default offset is .2 in inch units. For small holes, such as 1/4", the value should be decreased to 0.1, which will pierce just about in the middle.
