Apologies if this is in the video, I am not in a location where I can view it. How much did building that machine cost in total? And how long did it take?
I used lots of surplus parts from eBay, collected over 5-6 years. The actual build process took a few months of pretty focused night/weekend work (10-20 hours per week). Total cost was around $1500. Details here: https://www.youtube.com/watch?v=L6HxTk9tfQk
