Welcome back to Aurora Tech Channel. In my last video, I reviewed this Comgrow Robo CNC. Since the frame of this machine is quite rigid, I would like to upgrade the stock 60-watt spindle to an 800-watt one so it can make some aluminum parts. As the 800W spindle is much larger than the stock one, I have to re-design the spindle mount. I will show you how to do that in this video by using the measure, mirror, offset extrude and midplane tool. I will install this 800 watts spindle to the Comgrow Robo CNC in my next video, I will put it inside the CNC playlist of my channel, if you are interested to see how it works, please check out my channel next week.
