I started EXACTLY at the place you are a number of years ago. End result: I ultimately rejected the home brew machine, and bought a commercial machine....after I had spent a huge amount of money learning what I didn't know prior to the start of the adventure.
My prediction: you will spend more money building your home machine and get poorer results than if you followed my suggestion. Let us know what you actually spend on your machine and how well it works out in the next 3 years.
So you learned a lot and that's a bad outcome? No details at all about the 'mistakes' I'm making that are presumably the same as yours, lots of assumptions about what I've paid. Maybe I'll be more successful than you? Would that make you sad? Maybe sharing the mistakes you made instead of 'solving' my problems with a ill informed hand wave would have been more constructive.
Now, if you are really wanting to just learn how to build machines, and just doing this project for the fun of it, then I TOTALLY encourage you to proceed...you will indeed learn a huge amount in the process. But, IMHO, you will still end up with an inferior solution to even a very old professional CNC machine. Ultimately what is your goal: learn a lot on a fun project, or have a working machine to build other stuff....
Read what I've actually said about the project and my goals. Why would someone build this if not partially for the learning experience itself? Have I ever implied that I expect this to have higher accuracy (or really be better on any performance metric) than a professional machine? No, I haven't. Better than a Shapeoko, sure, not an audacious goal I think we can all agree. It is being built to accommodate the many constraints I have, that I've documented and discussed, that a professional machine wouldn't be expected to meet.
Also, be a little careful about believing you are the only person on this forum that knows and understands Japan. I myself have spent a lot of time in Japan and know the culture and country well.
LOL, people on this forum are always projecting what I 'believe' so that it fits their narrative. I don't assume that I'm alone in my understanding, but I do question your understanding for making the original suggestion. If you know so much about Japan then you'd easily be able to back it up with facts and be able to document where I'm wrong. Show me the cheap industrial real estate listing in Shabuya-ku you found. Put me in contact with your best friend at Tepco who can get a 200A 3-phase drop to my place.
Otherwise, get with the program and be constructive or keep your misguided solutions to yourself.
