My Homemade CNC machine.

My CNC Machine is made from various office machines, aluminum stock and was designed for machining foam. It had a sewing machine motor until an early version of Turbocnc v4 drove the z axis down into the table. I stopped the project and quickly designed a motor mount for the dremel. The sewing machine motor was grinding and smoking as it cut out the new motor mount. It quit at the very end leaving me with a small amount of hand finishing and only one chance to cast it right. I put sprues and runners all over that thing, very excessive but it worked.

Picture of the machine and foam after a 14 hr run. This piece had many alignment flaws. I couldn't find any problems with the machine so I slowed it down and ran another one. Still had flaws but less pronounced. Then I changed the post processor from radius to IJK values, ran another at full speed and it turned out perfect.

This is a time lapse video captured at 1 fps. The machine is working on a surface contour toolpath. My goal is to make my next machine this fast.

Also time lapse but sped up 4 times. No way I could make the machine go this fast.

Turbocnc by DAK Engineering is highly recommended.
