The software was designed to interface with their Phlatprinter, but it now also supports standard gantry machines. I'm not sure what the difference would be in Gcode? Still seems Y would be Y and X would be X and Z would be Z.
Not sure why they are patent pending on the Phlatprinter. It all seems like it was prior art. Doesn't craftsman make a shop bot that moves the product back and forth?http://www.phlatboyz.com/Phlatprinter-3-Kit_p_9.html
An interesting variation could use a laser instead of the mill.
