The first thing I realized was that to make my machines for genetics and other projects, 3D printing will no longer suffice because I will be needing much heating & cooling elements exposed to more extreme temperatures than a plastic filament material like PLA or ABS cannot endure.
But with a CNC, I could make use of light metals in my manufacturing process.
Also, those machines always made me feel marvel, so no tough choice here. I wanted CNC for a long time now and this will come in handy now.
Of course, budget-wise I need to be clever about it, so I invested some time in learning about it and realized early on, that my Arduino skills will transfer. So I ordered electronics and a frame of CNC separately and will assemble everything on my own.
Here is the timelapse of the whole process:
