Can we DIY an Industrial grade CNC?

The next episode in the CNC adventure: https://youtu.be/zTQJpwYjUeg?list=PL95ElZTgRGGtT0P3tldoWugwNVCTGtErC This video: Making a big 'industrial performance' CNC router, that will hopefully mill metals. This CNC machine needs to earn its place in the workshop, so the plan is to make something that can cut 8 x 4 ft sheets and flatten big chainsaw milled slabs, as well as machine aluminum and steel parts. Making the unorthodox gantry video: https://youtu.be/obR-l7qVhQY Casting the z-axis video: https://youtu.be/Jh4MVzn61dg Making the z spindle plate https://youtu.be/l0d9gyGMwyw The washing machine speed control circuit video is here: https://youtu.be/xI6CF2nYf_g More videos on the CNC on our other channel FE4SuperNerds - https://www.youtube.com/channel/UCSgDIVbcssx_urdEGNwp9qw If you would like to play with the 3D model of this machine you can get it if you buy us a coffee here: https://ko-fi.com/floweringelbow/shop Metalized epoxy guide: https://ko-fi.com/s/bb8cbd72e1 The spindle motor in the video is a 240V single phase Jianken JGL-100mm 3.2kw 24000rpm BT30 ATC. It has ceramic bearings and thus far seems very very nice. We chose a 4 pole one, which has somewhat more torque at lower rpm than the 2 pole, but requires an 800Hz VFD. We will do a whole video on the spindle in the future. You can find them here: https://jianken.en.alibaba.com/ and if you do buy from them, message them and mention 'Flowering Elbow' to get yourself a discount!
