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!
