Short enough yes. Just remember to keep your eyes shut or better yet
buy proper goggles. Doesn't come with the fibre by the looks of
things, I wonder how much they are, at least that allows for a very
light gantry system and some hope of speed. I'm not sure even 17W of
915nm is going to be enough for any real building speed for the very
fact that plastics do not absorb it as much, it certainly will not be
equivalent to a CO2 of the same power.
