Changes

This mainly depends on the language your printer speaks. Currently, MatterControl supports two languages for communicating with the printer; [http://reprap.org/wiki/G-code GCode] and [http://www.sailfishfirmware.com/doc/details-s3g-and-x3g.html S3G/X3G]. GCode is the standard language used by RepRaps and most other printers. S3G is a condensed language used by Makerbot and Flashforge. Most consumer 3D printers speak GCode.
