Hello Clara, first I am a big fan of your videos. You said that the fact of having laser beam perpendicular to the shiny materials may damage the laser source, I have a laser source mounted on a robot arm so I can change the angle, so am I safe when I cut with angle? and at what angle should I cut? and if I understand correctly the main problem is in piercing, so is it optimum to pierce on an angle and then return to perpendicular or only a little angle?
