A method for ordering parts for a machine being serviced within an e-commerce environment transmits diagnostic data from a local computing device at the machine to a host computing device via a network. The proposed scheme utilizes new algorithms that introduce randomness using a physical value for authentication. When the system is rebooted, it is determined whether to drive the system based on an additional cutoff voltage, if the flag is set. Additionally, the safety apparatus includes a safety device moveable between a locking position and a non-locking position.
