With today’s advancements in computing hardware, most users will have no issues using their old or new computers and laptops to run their CNC machines. Generally, as long as your computer is newer than 5 years old, you should have no issues running a g-code sender like UGSPlatform to run your machine. This page discusses hardware requirements and considerations to make for running your CNC machine.
Your system requirements may change depending on
These are the minimum system requirements we believe will provide the best experience with your CNC machine. These requirements will suffice for sending g-code and controlling your machine. However, please refer to system requirements for CAD and CAM software you may use.
Operating system: Windows 7/8/10, MacOS, Linux.
CPU: Intel or AMD processors 2Ghz
Ports: USB 1.0
Memory: 200Mb of hard drive space.
An internet connection is not needed to run and operate your machine. However, you will need an internet connection at least one time to download the required software to operate your machine. Some programs such as CAMLab and Easel require an internet connection to work, but you can do design and g-code creation from one computer and use a separate computer to run the machine. If you require a setup to work completely offline, programs such as Vectric V-carve and Carbide Create offer the ability to design and generate g-code without an internet connection.
A computer must be plugged in via USB and operating while the LongMill is in operation. Here are some considerations on your computer setup.
Having a computer located close to your CNC machine may expose it to dust. We recommend placing it in a location that is out of the way of dust. 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).
Dual computer setup
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. 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. G-code can be transferred between computers just like any other file, such as via USB stick, email, or the cloud. This allows users to do their design and CAM work in one place and do their CNC work in another.
Some jobs can take multiple hours. If you are using a laptop, ensure that you are plugged in or have enough battery life to complete your job.
System requirements for design, CAD, and CAM software can vary widely depending on the complexity of the software. For example, Solidworks, a full-fledged, industrial CAD software recommends at least 16GB of RAM. On the other hand, cloud-based programs such as Onshape and CAMLab only require access to the internet and can even run on a smartphone.
For users that are just starting out, our recommended basic system requirements should provide enough brunt to handle most software. If you are using more advanced programs, please consult the documentation for the software that you plan to use.
Computer/tech-savvy users can run a g-code sender using a Raspberry Pi. A Raspberry Pi is a low cost, single-board computer that can be used as a dedicated computer to send g-code and operate the machine. Some benefits include
There are many different ways to set this up, and more information can be found online. While many users have successfully set their machine up with a Raspberry Pi, it can be complicated and may create new technical issues.
