Equipment Details
Zorro is a wire cutter that we built during the machine building class of 2022. It is an aluminum extruded frame with 3D printed and laser cut parts. It is driven by Nema motors and uses a modified version of the URUMBU mechanical drive design. The electronics hardware is an Arduino CNC shield with a GRBL control firmware. Zorro’s specifications are included below.
