Article note: There are details I would quibble about (I can claim experience, I've had 3-ish machines myself and helped others with several more) - only discussing grbl derivatives for machine control, no bldc spindles, no discussion of coolants/blowers, etc. - but it is, generally speaking, a really nice intro that covers most of what someone should be thinking about if they want a baby CNC machine.
