I have a cast-iron frame, 4mm ball screws, 170lbs of steel, 350lbs of granite, $25k worth of servos and $10k worth of spindles and turning that into a precision sub-micron CNC machine is a journey. I'm pissed that the $140 worth of steel cost me $370 because of scarcity but the $25k worth of servos cost me $2200 because they get used a lot on screenprinting equipment so they're readily available used.

(not shown: shit-tons of wires and cables)

Takes a lot of time tho

Have to keep reminding myself that I'm doing two things: (1) building a giant moat between "what I can do" and "what everyone else can do" (2) Building a $250k CNC machine through almost pure sweat equity.

Sister's family was in town. Lived through that. Sister-in-law's family is next week. May survive that. Air conditioning will be in in six weeks and I'll be the dog in the hat at the table with the cup.

The LCD on my 3d printer literally died from heat. Guessing the garage hit 120, 130. So did the CPU for the Jumbotron - we measured 111 there and it lives in a black box above a parking lot. New LCD is $27. New Jumbotron is $70k.
