Subtraction – Week #2 SKILL BUILDER: Other Mill

This week we got to know the Other mill, which is a really small CNC machine. It’s using 1/8 inch bit and smaller, and really good in cutting small parts from different materials, including metal, Plywood, Aluminum,  PCB boards and more.. I started with cutting some pieces of wood and aluminum. I used 1/8″ bit and plywood.

I cleaned the bed and the machine itself before I started.

After placing the material, I calibrated the bed (Homing) and also oriented the bit.

I decided to go with a small refresher tree shape. I divided the work to three different files : tree outline, rounded cut through hole, and rounded rect engraving. I manually placed them in place because I didn’t have any marks to align to. I should do it next time.

This is what happened in my first tryout when I didn’t divided the layers:

And this is the result after I made the cutting in 2 different operations:

After the second round, I went back to the machine and this time with Aluminum. I measures the material and gave the engraving and the cutting new numbers.

The machine ended the operation a bit far from the edge of the material but I was was able to take it out.
