CNC Machining Endcaps for the Curiosity Rover Replica! In a previous Wednesday Widget, we machined the UHF Antenna on the Tormach 770 and Slant Pro. Beatty Robotics tried 3D printing the endcaps before deciding they wanted them machined! How do we tackle this as a job shop job? A one-and-done approach is the best way to go. We use the super glue technique (YES, AGAIN) and our Haas Vf2ss to complete the job. They turned out great!
