-* The "​reprap"​ dialect, for 3D printing +* The "​reprap"​ dialect, for 3D printing ​(NOT NIST compliant) 
-* The "​grbl"​ dialect, for CNC milling+* The "​grbl"​ dialect, for CNC milling ​(Generally NIST compliant)
  
 The "​grbl"​ dialect is the closest to the "​normal"​ Gcode standard ( NIST ), and is adequate and useful for CNC milling. The "​grbl"​ dialect is the closest to the "​normal"​ Gcode standard ( NIST ), and is adequate and useful for CNC milling.

 However, more CNC oriented software can also be used to control lasers ( they are virtually similar to a CNC mill with a very thin tool and no Z axis ), this is the case for example of [[bcnc]]. However, more CNC oriented software can also be used to control lasers ( they are virtually similar to a CNC mill with a very thin tool and no Z axis ), this is the case for example of [[bcnc]].

 +Typical differences between 3d mode and CNC mode are:-
 +
 +1. Error messages are different
 +2. G28 goes to park position and is NOT home, $H homes in CNC mode
 +3. Many GCodes may be differently interpreted in CNC mode than in 3D mode, please check your gcode references (Linuxcnc has a good GCode reference, do not use the reprap gcode reference for CNC mode)
