Is the STEPCRAFT CNC system able to engrave or cut through carbon fibers?
Yes, the STEPCRAFT CNC will cut carbon fiber very well and very accurately. However, due to the hazardous nature of the carbon dust, STEPCRAFT has a Milling Bath that can be used where you cut the Carbon in water and the water captures the dust not allowing it to become airborne. You can see the Milling Bath here: https://stepcraft.us/product/milling-bath-840/ (They are available in sizes for the 420, 600 and 840 machines)
