Calibration Cube 40x40x40

thingiverse

I'm just starting out and I'm sure experienced 3D makers will find this elementary. For a newcomer, getting my first machine to do what it's supposed to (or at least what I want it to) has been a total game-changer thanks to this calibration tool. Everything finally fits perfectly now. I've made a new one that prints faster and uses way less filament. The x&z arc should come out smooth, 40mm from corner to edge as you pass your calipers over the crescent with the opposite corner as a pivot. Plus, you get all three axes measurable separately. The inside of the bottom square should be 36mm X and Y if your settings are spot on. It only takes six grams of PLA to check your settings. This is a super handy way to see if your steps per mm are calibrated correctly. Then apply a basic fraction equation to adjust the steps per mm on your system if your cube doesn't come out 40x40x40 as intended. (X Steps Per mm of Print * 40)/(Printed X mm)=(New X Steps Per mm) (Y Steps Per mm of Print * 40)/(Printed Y mm)=(New Y Steps Per mm) (Z Steps Per mm of Print * 40)/(Printed Z mm)=(New Z Steps Per mm)
