Simulation

Overview

Usually the best simulation is done within the CAM Software such as HSMExpress. It’s also possible to simulate outside of cam via a couple of methods to see how the milling head will follow the path while milling

Chillipepr

Chillipepr has its own simulator that can be used to get a preview of the G-Code path within the browser window.

Something to be aware of is that Chillipepr has problems with curves in the simulator, it seems to just follow a diagonal line across the arc. When it comes to actual milling though this isn’t a problem as the firmware of the CNC will perform the arc correctly and send feedback to Chillipepr as to its current location.


Camotics

One app you can download and use to simulate the G-Code is Camotics. This can be used to give you a simulation of what the part will look like once milled.
