This tutorial demonstrates the necessary on-site preparations for CNC milling, up to warming up the spindle and assembling tools, in the context of aiming to utilize the CNC router in the KTH Architecture school Workshop. Succeeding steps are demonstrated in the next video. This tutorial serves as a thorough introduction to beginners, and lacks in brevity, which might be frustrating for experienced users. Please also note that the audio captured is at times very noisy, due to being recorded in a sometimes extremely noisy environment – efforts at denoising it only got rid of the lower frequencies, and the higher frequencies left alone was even more painful to the ear, so it has been left undenoised.

Timestamps:
0:00 Entering the CNC room
0:20 Make a quick tool inventory, to verify that the intended router bits are present
2:10 Make sure that the compressed air valve is open, and that the pressure is at 100 PSI
3:03 Verify adequate levels of the spindle's coolant fluid and the vacuum machine's oil
3:43 Preparing for the warm-up operation, and introduction to tools and tool holders
8:37 Making sure that you have the necessary amount of sets of chucks, nuts, collets and router bits free for you to assemble, as well as disassembling a tool
13:55 Starting the CNC machine
14:55 Verifying the integrity of the spindle's chuck
18:02 Homing the machine (finding the machine's hard home)
19:43 Final preparations before the warm-up operation (e.g. moving the computer table outside of the glass doors)
23:39 Executing the warm-up operation
24:49 Moving/copying the toolpath files to the synchronized directory (C:\dnc_files\)
28:17 Assembling your tools, including cleaning dusty parts
37:52 Placing tools in the tool holders
41:01 Repeating the assembly procedure for the other two tools

This tutorial aims to increase student awareness of the versatility of the digital tools available for use within the context of the architectural education offered by KTH. As such, it might not be generally applicable, but on the other hand, if even one student is helped by it with fulfilling deliverables requirements, the purpose of this tutorial is satisfactorily achieved. There might be inaccuracies in this tutorial video – if you identify any significant one, please tell us in the comments.
