LW3 speed optimization tests

@cprezzi
Can you post the gcode you used for this?
I will compare the results on our setup.

Does there appear to be any roughness in the engraving sections (ie, not when its skipping white pixels)?

@Domenic_Di_Giorgio ​ This was Grbl. I think you are using Smoothieware?

@cprezzi Yes, we use Smoothie.
