This GIST is all about flighttracking and sharing data with other sites as adsbexchange, flightradar, flighaware, planefinder etc.
Things you need to install, to track planes and stats:
;End GCode | |
M104 S0 ;extruder heater off | |
M140 S0 ;heated bed heater off (if you have it) | |
G91 ;relative positioning | |
G1 E-1 F300 ;retract the filament a bit before lifting the nozzle, to release some of the pressure | |
G1 Z+0.5 E-5 X-20 Y-20 F{travel_speed} ;move Z up a bit and retract filament even more | |
G28 X0 Y0 ;move X/Y to min endstops, so the head is out of the way | |
M84 ;steppers off |
% This is a modified version of matlab's building rref which calculates | |
% row-reduced echelon form in gf(2). Useful for linear codes. | |
% Tolerance was removed because yolo, and because all values | |
% should only be 0 or 1. @benathon | |
function [A] = g2rref(A) | |
%G2RREF Reduced row echelon form in gf(2). | |
% R = RREF(A) produces the reduced row echelon form of A in gf(2). | |
