Yes i know it's a dumb and brave build. (using blueprints too

) But i have a question, At my school we have this machine that you make a design on the computer, and then the macine cuts it according to the design, Is it safe for plasti card (1.5mm thick), It doesn't use a laser.
Oh and i need some tips, If anyone wants to see the blueprints (not made by me) just ask and ill post it.
Thanks
