Today I’ll be using JSCut Like the previous two CAM programs this one is also free and browser based. Months ago JSCut was the first CAM program I tried to use and all of the options didn’t mean anything to me and I gave up almost immediately. JSCut seems to have more options available than MakerCAM or Easel, but maybe that is just because they are always visible.

JSCut Steps

  1. Operations => Select px per inch
  2. Tool => Units (mm)
  3. Tool => Pass Depth (1.5)
  4. Open SVG => local file
  5. Material => Units (mm)
  6. Material => Thickness (5)
  7. Edit ToolPaths => Select Square
  8. Create Operation => Outside
  9. Create Operation => Deep (5)
  10. Operations => Generate
  11. Save GCode JSCut steps

OpenSCAM

Looks good, although by default the tool begins not at the origin. JSCut OpenSCAM

Resulting GCODE

Four times as long as Easel and 8 times as long as MakerCAM!
