Our New $10 000 Router!

This video documents the Linus Tech Tips team building and testing a large four by four foot CNC router, aimed at handling tough cutting tasks with a high level of precision. The host presents the project as a deliberate shortcut to achieving advanced machining capabilities without years of trial and error, explaining that the machine will handle the difficult milling work traditionally done by hand. They walk through assembling the frame from extruded aluminum, noting its rigidity and modularity, and describe how the gantry, spindle, and linear rails are integrated for smooth operation. Throughout the build, the crew highlights the scale of the components, including a powerful 2.2 kilowatt spindle and a compact but capable 3.0 horsepower drive system, emphasizing how the system delivers high torque and fast cutting while maintaining control. The video then shifts to the electronics and control software, introducing Mach3 as the interface that runs G-code, and discussing the importance of proper parameter setup and safety interlocks before powering up. Finally, the team discusses ongoing upgrades and future capabilities, such as adding a dust collection system and a spoil board, and thanks CNC Router Parts for providing the machine while inviting audience ideas for future projects and naming the newly built router.
