25:17 Pros and Cons

Welcome back to Aurora Tech Channel. Today, I will be testing the Genmitsu 4040 Pro CNC router. In addition to the stock setup with a standard 75W spindle, I will be experimenting with two spindle upgrades. The first upgrade is a 300W spindle that can be directly dropped into this machine, and the second is a powerful wood router like the Makita RT0701, which has a horsepower of 1 ¼ or 800W. I'm so excited to see the cutting power and how well these upgrades work with this machine.

Let me give you an overview of the machine's features. The working area is 400x400mm, and the Zheight is 84mm, allowing for thicker materials. The machine frame is made of aluminum, and the X and Y axis use dual 16mm steel rods, making them super rigid. The Zaxis uses 10mm rods, and the frame has panels to protect the lead screws from debris. It uses standard Nema 17 stepper motors, and all of them have a jog wheel for manual axis movement. The machine comes with a 2piece MDF spoilboard with M6 threads all over for clamp mounting. It also includes a Zprobe for stock and tool height adjustment. The frame can be mounted on a workbench to ensure stability. The control board supports an offline controller and 4axis roller, but these are optional upgrades that need to be purchased separately. Overall, for the price of around $500, the hardware looks impressive. I would like to thank Genmitsu for sending me this machine to review, and with that, let's get started.
