Hi, new to the forums and new to laser cutting.  We bought the XToolS1 with the 40W laser.  My students are now saying it can't cut clear plexiglass.  We are a robotics team and bought the laser for this purpose, as we are limited in the materials we can use.  Any guidance would be much appreciated!  Can we buy a CO2 laser to attach if that is what is required to cut clear poly?  Thanks!
