---------   Gcode Basic Summary ---------
The LCAM supports the following Gcode commands. The Gcode is basic
Fanuc compatible and has been tested on a 21MB fanuc control.

G00  Linear Rapid
G01  Linear Feed
G02  Arc 
G03  Arc
G90  Set absolute

It Supports the following Mcodes
M06 T (followed by tool number)
M30 End of program


G00 followed by xyz coordinates is the Rapid move with the tool up
Here is an example program.
(The comment shouldn't be in the real file)

EG:                                         Comment 
G90                    ; specifies absolute coordinates
G00Z0.75               ; raises the Z axis to .75 above the work
G00X1.00Y2.125         ; moves the machine to (xy)   1 , 2.125
G01Z-0.25              ; drop the Z axis into the work .25"
G01X4.0                ; move the X axis  only to 4.0
G01Y3.5                ; moves the Y axis to 3.5
G00X1.0Y1.00Z-0.5      ; 3d move of x,y,z
M30                    ; end of program

Notes:
- The G00 and G01 are Modal which means that you don't need to specify an 
  xy or z position if the machine is already there.  You can use xy and 
  z in each line , but the file gets bigger.
- G02 and G03 arn't modal and require the complete line X,Y,I,J
- In circular (G2,G3) XY are absolute and I,J are relative to the center.
- There should only be 1 Gcode per line. 
  If there is more than one then only the last gcode is used.
- Use absolute coordinates (G90)  only, not relative 

Tool change

T2     ; Tool change to tool 2 This will do a Layer change in Lcam to Layer 2
