Samples: 3 x 22

Mill bit broke on sample 2 of 0.4 mm/s

Fracture probably happened during pass transition at 01:24:25.

Seems samples need more spaceing, since tissue is softer. Current spacing is 1 mm.

All samples at 0.3mm/s did not completely detach from the slice.

Mill bit broke on sample 8 on first pass

 - The right side of the slice becomes raised at 20:40 - 20:45 because of too little support from the arms. This caused the first pass of sample 8 to be too deep.

The cut quality seems higher on 1.1 mm/s than 1.7. Even though the mill bit did not break i would recommend max speed at 1.3 mm/s.

The "pipes" in the lungs are much harder than the rest of the lung, which caused the slice to break. Increased vibrations can be seen on each pass over these areas.

Had to switch to a different type of mill. same specs, but entire mill bit is ~2mm longer

Mill bit broke at second line of 0.2mm/s

Arteriene i lunger blir for vanskelig å forholde seg til, så vi vil heretter prøve å unngå de i framtidig testing.

Popping does not work on lung tissue, tissue too soft.

Forgot to compensate for startheight in previous testings, will therefore return to 68.
