It also controls whether the head should be turned on and off and other things. You control a CNC machine using a G-code file, which has commands that tell the machine where to move the cutting head. The CNC can also engrave what the button does right next to the hole that it has created. This is a big advantage if you want to create some button holes in a panel.

Hobby CNC machines look a bit like 3D printers, with the ability to move in at least X, Y, and Z dimensions, but instead of extruding plastic to create things, they have many cutting bits that let you slice away material to expose the final object you want.Ī CNC can remove just a small amount of material, create holes right through something, or use a cutting head to engrave something on a panel. Instead of measuring this out and using a drill press, you can attach your control panel to the cutting area of a CNC and have the machine create it for you. At the simpler end of the spectrum, you might like to create a control panel with buttons at set distances from each other, or perhaps you also want a square hole for a display. The object can be as simple as a few holes in a panel for lights or as complex as a large engine.

A Computer Numerical Control ( CNC ) machine interprets a series of commands and creates a physical object for you.
