PCB Milling using FlatCAM

I want to mill my PCB using G code file . for that i use FLATCAM and generate Gcode file. i tried to import in easel but facing following error. any one help me to find solution or tutorial.

Invalid G-code

Line 6: G00 Z0.1500
The file contains invalid G-code syntax.
You must use one of our official post-processors in order to import external gcode.

One of these posts might help…


I am using FLATCAM new to this. so any one help to clearly define complete procedure to make acceptable GCode file. as Easel have no import link for FLATCAM.
