Before I search through logs and video, does anyone know who cut this material on the laser? Based on the results it does not appear to be a laser-safe material, so we would like to identify the type and origin. At first glance it appears to be acrylic, but it does not behave as such.
As a reminder, only use approved materials on the lasers. If in doubt, make a forum post or email fablab@makeict.org.
