First real milled pcb board (almost)

Been busy tonight. I almost have the hang of this milling thing. My traces are still way too thin, so I need to work on the parameters. Some of it is because of run out, but most is just learning the parameters.

Using version 3.5.2.11 of pcb-gcode, here are my settings:

Etch Options
  • Etch top
  • Probe & auto level
  • Etch depth: -0.003
  • Isolation default: 0.005
  • Isolation maximum: 0.03
  • Isolation step size: 0.005
  • Etch tool size: 0.01
  • Spot drill holes depth: -0.011
  • X Y Rate: 9 in/m
  • Z Rate: 10 in/m (my machine maxes out at 3)
Leveller
  • Probe grid size: 0.25
  • Tool probe max: -0.1
  • Probe Traverse Height: 0.04
  • Probe depth: -0.02
  • Probe feed speed: 20 in/m
  • Probe Z speed: 2.36 in/m
General options
  • Gen top outlines
  • Spot drill holes depth -0.011
  • Isolation
    • Default: 0.005
    • Max: 0.03
    • Step size: 0.005
  • Etch tool size: 0.01
Machine:
  • Z High: 0.1
  • Z up: 0.05
  • Z down: -0.003
  • Drill depth: -0.032
  • X Y speed: 9 in/m
  • Z speed: 10 in/m
I created the board in Eagle. The traces are supposed to be 24mil thick. Here's a picture of the layout:

Here's the result:

The traces are really thin! Not sure what to change to get them thicker...

Any advice would be appreciated!
