Cutting a balsa circle on a cnc router

Cutting a 1 inch diamter circle out of balsa wood using a table-top cnc router I built. This is similar to another video I posted but is using a shorter, smaller and sharper tool. The result is much better. I also increased the cutting speed a fair amount which is more impressive. The router itself is a dewalt laminate router and it is controlled by a custom 3 axis gantry. The gantry is driven with steppers all controlled from EMC2.
