Robot Portraits

Robot portraits are made by taking a photo of a person or object and processing it into a line drawing to be drawn with the Shapeoko CNC Machine using a pen/sharpie adapter.

Carbide Create Setup

• Set the material to be as thin as possible
• Set the retraction to be as small as possible
• Use the contour path tool
• Use the Sharpie 400 Custom endmill, which is set to the maximum feed rate (roughly 393 in/min)
• Make sure that the bottom of cut is set to the bottom of the material (very thin)

Notes

Here are some examples of the same drawing being draw at different feed rates.
