Other setup
* Absolute- A series of numerical positions that are calculated from a fixed point of origin.
* Clearance Plane- A plane designated for safe tool travel in between cutting functions.
* End point-The point where an arc ends
* Incremental- A series of numerical positions that is referenced from a previous position and is independent of absolute origin.
* IPM-A unit of velocity used to determine feed rate. (inches per minute)
* Origin- The fixed, central point in the Cartesian coordinate system. The origin has a numerical value of zero.
* Start point- The point where an arc begins.
* $120=1 - Set X acceleration to 1mm/s^2
* $120=1000 - Set X acceleration to 1m/s^2

== Gcode Data ==
=== From Drawing Inkscape ===
Use default extension - Gcodetools - path to Gcode
* Note - move path to 0,0 point in inkscape
* Note - mirror drawing in case the machine don't understand.
Use extention - J Tech Photoics, laser cutter
* http://jtechphotonics.com/
* No need to change any settings.

== Gbrl servo ==
* Command is: M03 S60, S - range from 0~255 for angle
* Github - https://github.com/robottini/grbl-servo

== GBRL Setup ==
* GBRL firmware support commands via serial port
* Enter $$ to see current GBRL setup, list here for example:
$0=10 (step pulse, usec) step pulse

$2=0 (step port invert mask:00000000) set 0 to close it
$3=11 (dir port invert mask:00000110) invert axis direction
$4=0 (step enable invert, bool)
$5=0 (limit pins invert, bool)
$6=0 (probe pin invert, bool)
$10=3 (status report mask:00000011)
$11=0.010 (junction deviation, mm)
$12=0.002 (arc tolerance, mm)
$13=0 (report inches, bool)
