PCB milling
I use FlatCAM version 8.99 to generate gcode from Gerber files. I've had some good results with the following settings. The settings are a bit conservative so you might be able to speed some things up.
Gerber object:
- Tool dia: 0.01 (0.1 is also ok, I had to use this for a specific board layout)
- Passes: 1
- Pass overlap: 0
Geometry object:
- Cut Z: -0.0030
- Travel Z: 0.7
- End Move Z: 1.0
- Feedrate XY: 8.0
- Feedrate Z: 10.0
- PostProcessor: grbl_11
Drilling:
- Cut Z: -1.8
- Travel Z: 0.7
- End move: 1.0
- Feedrate Z: 200
For the cutout I've used the Cutout tool.
I've used the Makita router with a 30 degree 0.1 v-bit (3.175 mm with a little collet) with a speed of approx. 15.000 rpm.
The result looks like this:
As you can see the drill holes have a little offset. This is due to the tool change. It's better to store the zero xy position from the trace operation. Then do a full homing cycle and after that return to the stored position.
