If you are using a laptop, ensure that you are plugged in or have enough battery life to complete your job. This allows users to do their design and CAM work in one place and do their CNC work in another. G-code can be transferred between computers just like any other file, such as via USB stick, email, or the cloud. Because the system requirements for most g-code senders are quite low (we’ve managed to run machines on AMD Athalon and Raspberry Pi’s), a less powerful computer can be used solely to send g-code and run their CNC machines. Some users may choose to use a spare or inexpensive computer to run their machine and use a higher performance computer for CAD and CAM design in a different location.
Each LongMill kit comes with a 1m USB cable, however, if you wish to extend the distance, a longer USB cable can be used (USB A to USB B). We recommend placing it in a location that is out of the way of dust. You can either use the file menu in the top left portion of the window or copy and past your g code into the g code window on the left. Still, having at least a superficial understanding of what the most common G-code instructions do goes a long way for troubleshooting why the machine behaves the way it does. One can perfectly use the Shapeoko without any understanding of the G-code syntax, or ever opening a generated G-code file. Having a computer located close to your CNC machine may expose it to dust. So the CAD/CAM tool generates G-code files. Here are some considerations on your computer setup. G-code is created as the output from sophisticated CAD/CAM (computer aided design/computer aided manufacturing) software. A computer must be plugged in via USB and operating while the LongMill is in operation.
