Okay so an interesting quirk of my #3dprinter (if you can call it that) is that the fans are adjustable up and down. Since I have no way to CFD the design quickly, I've never really known where they should point or be installed to. I have just guessed and tried locations. Are they too high (ineffectual and cools the heat block/nozzle)? Too low (cools the part, at risk of snagging or dragging on the print)? Tough to say! And an idea just hit me. I have a thermal camera! It's not perfect but I can crank everything up to temp and dial in the range of the thermal camera to see the effects of cooling on the block/nozzle. And it should be way way faster than modeling and doing #cfd on this design. I don't know if the active heater will be a problem but I think it SHOULD work! Right? #nerd #someLikeItHot #noNoTooHot
