LaserScript: Test pattern

Using the following LaserScript you can test several power and speed settings at once. See LaserScript for more information.

var rectangleWidth 	= 3;
var rectangleHeight = 3;
var space 			= 1;
var numX			= 10;
var numY			= 10;
var startPower 		= 10;
var endPower 		= 100;
var startSpeed 		= 100;
var endSpeed 		= 10;

var speedStep	 	= (endSpeed-startSpeed)/(numY-1); // speed over y-axis
var powerStep 		= (endPower-startPower)/(numX-1); // power over x-axis
