Hallow Calibration Cube

The Hallow Calibration Cube is a basic Calibration test designed to measure the accuracy and extrusion rate of FDM printers. This simple test takes less than an hour to print and under 10 grams of material.

For video information on this calibration test check out our youtube video on the hallow cube.

Settings
The ideal settings for this print allow for a base level assessment that lacks bias. Using the settings to the left can be great for testing out the machine’s accuracy and/or new materials to ensure that they are extruding correctly. If you want to be ambitious you can test new print settings to get dynamic material properties while ensuring that extrusion remains constant with the tuned settings.

Inspection:
In order to assess this model, you will need to use a vernier/micrometer to check;
Wall thickness (2mm ±.1) x 4 walls
Internal Space (23mm±.1) x 2 walls
Overall Height (25mm ±.15) x 4 corners
Internal Height (23 mm ±.15) x 2 spots
If you have checked all of these details and they are within tolerance than your machine is well calibrated for this material and you can feel confident printing. If not then we will need to determine the cause.
Wall thickness is not consistent:
Along 1 Axis: This typically shows that one of your axis is out of calibration.
Tighten the Axis Belt and run test again
If there is a consistent issue after tightening the belt, then the motor steps will need to be refined in the EEPROM.
All 4 sides
This is typically a sign of under-extruding/ over extruding of the material.
Check your slicer
Ensure that the extrusion rate is set to 100%
Filament diameter is set at the proper size for the filament you are using (yes if your filament is average 1.78mm instead of 1.75 this can cause over extrusion)
Perform an extrusion measurement test
Mark 100 mm past the tensioning bar
Mark 110mm past the tensioning bar
Feed 100mm through the controller
Measure the material remaining/missing
Repeat a-d 3 times to ensure accuracy and take the average of the answer
(Current Steps x 100)/New Length
1 Wall is different
Level the bed
Height is not consistent/correct
Corners are all the same but too high or too low
This means that the Z axis is not calibrated properly.
Perform the test 3 times
Average the difference in height over the 3 tests
Get the current Z step value out of the EEPROM
(Test Distance (25mm)×Stepper Motor Value from EEPROM)/(Average Height of the Cube)
Change the Z EEPROM Value to match the answer
2 Corners are different (on an angle)
Level the bed (I know everyone knows this, but I have to put it)
Single Z Drive
Figure out direction of the slant
Adjust the Z axis tensioning nut (check with your manufacturer) to straighten out the Z axis movement
Double Z Drive
One Port – Two Motors
Check the tensioning nut on the Z Axis Ballscrew and ensure one side is not loose, repeat test.
Check the Z Coupler to ensure it is holding tight to the motor and the ballscrew.
Check with your supplier as there is a definite issue that is machine specific
Two Port – Two Motors
Check the tensioning nut on the Z Axis Ballscrew and ensure one side is not loose, repeat test.
Check the Z Coupler to ensure it is holding tight to the motor and the ballscrew.
Check the EEPROM to see if there is a separate value for both Z ballscrew
If there is recalibrate using the steps from 2a.
