Test part for multi measurement for calibration.

Obsolet since V1.6.0 (removed from the plugin menu)

MultiCube Test

OpenScad MultiCube Test Model

MultiCube Test

Licence for the standard calibration cube: CC BY-SA 3.0, I don't know who have used for the first time this model as test part. One 'similar' and remixes object can be found on thingiverse. But if the idea is the same, it's not exactly the same design and in this case no geometry have been added to test bridging conditions.

Printing Conditions

 - Nozzle Size : 0.4
 - Layer Height : 0.2
 - Initial Layer Height : 0.2
 - Line Width : 0.4
 - Wall Line Count : 3
 - Top/Bottom Thickness : 0.8 mm
 - Infill Density : 8%
 - Fill Gaps Between Walls (Only for release of Cura previous to V5) : Nowhere

Printing Time = 1h30 mn

Dimensional accuracy

Use a caliper to measure the dimensions of each block and the depth of each level.

If the dimensional inaccuracy scale with the different part of the cube, then it's the steps/mm of your steppers that needs some adjustments.

Note: if it's the case, you should also adjust the flow, and maybe redo some calibrations if the change is important.

If it doesn't scale, you can correct it by adjusting your Horizontal Expansion.

Base Layer Height

If your base layer is too low, then that will affect the first few layers of your print. by measuring the first level height you will be able to quantify the Z offset you must add to your bed leveling.
