	After testing some sample materials, these values were selected based on giving the best visual impression. That includes minimal charring and smoking, best accuracy, and are ultimately entirely subjective. Use these as starting points for your experiments.

			===M68 Command===
			The M68 command is used by LinuxCNC to specify an analog output. Our laser is configured to use the E0 output and the Q parameter to modulate the laser power when cutting in automatic mode. Based on previous testing a Q value less than 0.12 are insufficient to even brown paper at most speeds. Values greater than 0.6 will cause the laser to exceed its maximum current. For than reason, this parameter is internally limited to 0.6. Putting in larger values will not have any effect.

			Samples:
			*M68 E0 Q0.125 - This would represent a very low power beam. Speeds would have to be very low to mark anything other than paper.
			*M68 E0 Q0.6 - This is the maximum laser power. At low speeds this will cut through most materials on our approved materials list.

			The F parameter specifies the feed rate for all following moves. This would be the linear movement speed of the lens carriage. The speed effects the amount of cutting that the laser beam does to the material that it moves over. At a given laser power, a slower speed will cut deeper or burn more, and a faster speed will cut shallower or burn less.

The Inkscape Plugin uses S10000 as the default on all cases. However, it is possible to create interesting effects by setting it to a low enough value that it perforates instead of creating a continuous cut.
