DIY CNC Fusion 360 CAM posts processor

This is modified fork of https://github.com/martindb/mpcnc_posts_processor

CAM posts processor for use with Fusion 360 and MPCNC with RAMPS or any 3-axis DIY CNC. Supported firmwares:

Marlin 2.0
Repetier firmware 1.0.3 (not tested. gcode is same as for Marlin)
GRBL 1.1
RepRap firmware (Duet3d)

Some design points:

Setup operation types: Milling, Water/Laser/Plasma
Support MM and Inches units (but all properties MUST be set in MM)
XY and Z independent travel speeds. Rapids are done with G0.
Arcs support on XY plane (Marlin/Repetier/RepRap) or all panes (Grbl)
Tested with LCD display and SD card (built in tool change require printing from SD and LCD to restart)
Support for 3 different laser power using "cutting modes" (through, etch, vaporize)
Support 2 coolant channels. You may attach relays to control external devices - as example air jet valve.
Customizable level of verbosity of comments
Support line numbers
Support GRBL laser mode (be noted that you probably to have enabled laser mode $32=1)
