Section 1: Overview of Functions

When you navigate to sim.pocketncpentamachine.com you will see the screen shown in Figure 1. First, a brief overview of the functionalities of the components of the Simulator outlined in colored boxes in Figure 1, moving counterclockwise from the upper left hand corner of the figure below:

The goal of the simulator is to be a helpful tool while debugging G code programs and learning to machine in general, but there are some important caveats when using the Simulator. For starters, since it is implemented independently of the software that actually runs on the Pocket NC, there is a chance that the behavior shown in the simulator will differ from the real behavior of the machine. We’ve made every effort to make you aware of situations where behaviors can differ between the simulator and a real machine by warning you when a specific G code that is used in your program isn’t implemented in the simulator. While we strive for the simulator to match the behavior of the real machine, bugs can and do occur, so precautions should always be taken when machining and you should never leave a program running on a real machine unattended, even if it checks out on the simulator. We hope you find the simulator helpful, and appreciate any feedback you may have.
