Previously, I made a few videos on upgrading the 3018 CNC, which is the cheapest CNC machine in the world. I put a 500w spindle on it and it can cut aluminum slowly with a quite acceptable result.
Since the structure of the CNC 3018 is not rigid, especially as the X-axis moves a lot when working on metal, I want to get another mini desktop machine with a more rigid frame. I recently found this Comgrow Robo CNC engraver. It came with an aluminum frame, larger diameter 12mm linear rods on both the X and Y axes, 6 limit switches, a Z-probe, an emergency stop button, and an offline controller.
Today, I am going to assemble and review this Comgrow Robo Mini CNC Router …
I am happy with this machine, for beginners to buy their first budget desktop CNC router, I would recommend this Comgrow Robo CNC over the cheapest CNC3018. I have purchased another 800-watt spindle and may make more videos for the spindle upgrade and make some aluminum parts with this machine. If you are interested please check out these links:
