Milling

Now that's a good reason to justify having bought this little mini mill. I need if for my electronics hobby :-)

The PCB is FR4 material, so I use carbide bits.

Milling off 0.3mm and getting it all wrong... I misaligned the PCB and I didn't mill at 0°. The 2nd attempt was successful using brackets and a different setup. Please note that a new hardware version of this device has been released, therefore these images will most likely not apply to it.

For easy access to serial / programming headers. Please note that a new hardware version of this device has been released, therefore these images will most likely not apply to it.

Not the most efficient way to get the length right. And apparently the end-mill will remember this job. Time to get new ones. I'm down to my last 3mm one. All others (the smaller ones) are already dead.
