CNC Routing.
After my purchase of the 3d printer I decided I needed more. Something of higher expense! Something of more power, dust and noise! I then turned to my wallet and found that hobby-grade machines on the market were too expensive for my state of poverity, and I wanted to dip my toes into the water at a beginner's price range.
Looking online and having no idea what I was doing, I built The Router-Inator 1000 (Yes, I spelled "Inator" wrong in the photo). She's made of 3/4" plywood, glue and screws. The accuracy comes from 1205 Ball Screws and Linear Rails. The motors are Nema 23's with cheap TB6600 stepper drivers powering the 4 motors. All of this is connected to an Arduino running grbl1.1 receiving commands from my laptop running UGS.
This machine has added another level to my toolbox of capability. No longer does it take 20+ hours to produce a large part like it would with a 3d printer. With some programming and angry router noises, this machine turns solid materials into accurate dust. Where the strength and the size of a part matters, the "CNC-Inator" reports to the job.
