Testing CAM Programs with SVG Part II (Easel)

Since this is part II you can find the settings I’m using in part one. Today I’ll be using Easel which is the software that is expected to work with the Shapeoko 2 that was donated to Quelab by Inventables.

First Attempt with Easel

My first attempt at duplicating my MakerCAM process ended in failure. Instead of cutting out the square it engraved the entire area of the square.

Easel-fill

OpenSCAM of First Attempt

I only realized I did something terribly wrong when I went to check the tool paths in OpenSCAM … oops. OpenSCAM Easel-fill

Second Attempt with Easel

File => Import SVG
Move the square to the center of the screen. Impossible to do an outside profile operation with an edge outside of the cut area.
Select cut operation Outline
Select Units mm
Materials => Birch
Materials => Z: 5 mm
Machine => Advanced
Machine => Advanced => Generate g-code
Machine => Advanced => Export g-code

Easel-fill

OpenSCAM Distance View

Notice that the resulting SCAM does a large machine move to the center of the cut area. This must mean that Easel expects the Shapeoko 2 to be zeroed at the machine origin and the top of the material first. OpenSCAM Dryrun

OpenSCAM Close Up View

The close up of the actual cut paths looks very similar to the cuts from MakerCAM. OpenSCAM Dryrun

Resulting GCODE

Twice as long as MakerCAM for some reason.
