Development continues on RC2. This version features the new locking mechanism, with tracking adjustment, more powerful motors, a transport locking mechanism, better cable and connector management

The machine was shown at the CHAMPS trade show in Las Vegas. Marcel used it on a large solid piece. As the piece reached about 6" dia and 5 in length, the machine struggled.
