The "Simulation" tab on an Acramatic 2100 controller is typically for graphical program simulation.
here's the detail.
Visualizing G-Code: It allows you to run your G-code program virtually on the controller's screen, showing the tool path and the resulting part shape.
Collision Detection (Basic): While not as advanced as external CAM software simulations, it helps you visually check for obvious collisions, rapid moves into clamps, or other major programming errors before you run the program on the actual machine.
Verifying Tool Paths: You can see if your tool is going where you intend it to go and if the cuts are being made correctly according to your program.
Saving Time and Material: By catching errors in simulation, you avoid costly crashes, broken tools, and scrapped parts on the machine itself.
Proofing Programs: It's a quick way to "proof" a program, especially if it was written manually or imported from a new CAM post-processor.
Think of it as an onboard sanity check for your G-code. It's a valuable feature, especially for complex parts or when you're trying out new programming strategies.
