Inverse Kinematics is really cool. Whenever you move your hand to a position, you're only thinking of your hand moving to that position, but there's an order of operations you dont even think about. For your hand to be in the right spot your forearm has to be in the right spot, and for your forearm to be in the right spot your upper arm has to be in the right spot. Your brain subconsciously calculates those movements. This enables very accurate motions, your hand can follow a smooth, deliberate arc towards your target

If only my 3d printer was so easy to control.

Clearly, you should drop it for a resin printer

Oh I'm planning on getting a resin printer in the future. It's just I'm renting right now, and have a toddler, so it's difficult to properly ventilate the fumes outside currently. Once I buy a house, that's going to be one of the first things I buy. Do you have any recommendations for something hassle free that I won't have to tweak for 6 months before it prints well?

And most people actually suck at it. Source: I do martial arts. Also, my Grandma taught me knitting same principle applies: If you start doing it with your fine motor skills, letting those influence your gross motor posture, you're going to cramp up in no time. Easy and relaxed does the job, move from the shoulders (or even belly), don't even move your fingers just keep them static knitting doesn't really require you to move them. Doesn't matter when all you're doing is opening a door or such but for repeated movements, or forceful ones, or ones that need to be stabilised against adverse forces (like a block) it becomes crucial.
