I make custom bamboo fly rods as a hobby and have never been happy with signing my rods by hand. I went to decals for a while but they fade eventually. Actually did the kickstarter backing because the design allowed for items larger than the cutting area to be lased. Letters and lines at 1200 mm/min at 65% and fill areas at 1200 mm/min at 50% with 45* hatch at .18 step over. Probably need to lessen power for fill or increase step over. Really pleased with the results so far.
