A freezer has been bought.

We found a CNC that has many elements we desire.

Its main issue is a bed that is too big. But it seems like it can be cut to size.

Mounting the camera on the same piece as the prostate frame would let the camera be focused on the slice at all times. We plan to use the same as used at MR Core Labs and in ARTS 1.0

We want several temperature sensors in our freezer to ensure the safety of the slices.

The temperature sensors costs ...

To make the Z-axis auto-calibrate, a smart Z-axis callibration tool should be bought and implemented as soon as possible. This makes operating the CNC a lot easier. 

The CNC shown above comes with a z-axis calibration tool.

The CNC shown above comes with end stops

This is to make fastening the clamping pins easier.
