What's stressful about it? At some point I want to build a hobby cnc.
There are numerous variables of things you have to watch and be aware of (tool wear, part flexing/distortion, taper, harmonics/chatter, thermal expansion coefficients of your material, et cetera), especially when maintaining tight tolerances such as +/- .0002 (5 microns), which I encounter pretty much daily. These issues become more critical when cutting hard, or fairly exotic materials such as F15 kovar, invar 45, 17-4 PH SS, PEEK, polyamide-imide(Torlon), PTFE (Teflon), and titanium. Keep in mind the boss wants the endless stream of jobs done NOW, so I have to use my time sparingly and wisely.
If you plan on making a hobby CNC, you have no worries, as you have all the time in the world to experiment and learn. I love machining, and would like to have my own lathe or mill, so I could tool around with it at home and possibly do small jobs. Don't let me scare you away from it!
