Precision Calibration - CHIA

First publication!
Precision torture test for BOTH printer AND slicers.
Print with slowest speed and 50% infill AND AGAIN at 5/10% infill
X carriage features 10mm cubes stepping down 5mm
Y axis features 0.5mm stepdowns upwards
Downward Y is 0.2mm stepdown and a 0.5mm inset.

WHAT TO LOOK FOR:

1. MASSIVELY IMPORTANT that if you're on ABS you allow your model to COOL before measurement
2. Trim model CAREFULLY, undercut if you need to in order to preserve the face
3. Look for edges being "square" and not rounded off, scalloped or distorted.
4. Differences between 5/10% and 50% infill will give insight as to how the material cools and "contracts"
5. Always observe perpendicular to the surface being measured with your calipers - observe dips or sags.

TAKE 3 PANADOL/ACETOMENOFEN and call me in the morning! Welcome to the headache of reprap!
