MAKE (in HDPE)

After all of my experiments with recycling various HDPE scraps, I finally got around to milling a piece on the Shapeoko at BAMspace.

Milling on the Shapeoko

The piece I used was close to 0.5″ thick. I added a thin piece of MDF beneath the piece so I wouldn’t chew up our nice looking hold-down surface…

The milling took quite a while. The first attempt with a different piece did not work out well, partly due to too high of feed rate, and partly due to a piece getting stuck after being cut out. (I can see the appeal of a vacuum table!)

GRBL Controller

We use GRBL Controller on one of my old Linux laptops to control the Shapeoko.

Did I mention the milling took a long time? It was about 14 passes at 0.04″ per pass to cut through. I used a 1/8″ bit.

The end results were nice. A little rough, but some sanding and a few hits with a blow touch should clean things up just fine.
