Jose Chambrot just posted a picture of a quad copter part he milled this weekend out of HDPE using ChiliPeppr. Pretty sweet. He’s got a modified Shapeoko 1m x 1m running TinyG.
Very nice. This link gives more information comparing between aluminum 6061 and HDPE. For quadcopter, this is very good. It’s no carbon-fiber but it is easier milled.
Looks Great!
