Don't waste your precious time and filament printing a so called “calibration cube”!
This quick print provides clues for all the important features and settings:
- Extrusion width
- E-steps / rotation distance (X, Y, Z)
- Bridging
- Cooling
- Overhangs
- Speed / accelleration
- First layer / bed adhesion
- Retraction (stringing test, seam test)
- Preassure advance / linear advance
Print Settings
The settings for a standard 0.4 mm nozzle:
- No Infill, No top layers
- 1 perimeter
- 0.2 mm layer hight
- 3 bottom layers
- Disable “Ensure vertical shell thickness” (PrusaSlicer)
- No brim or supports

Some quick tipps:
- Extrusion width
Check if the thickness of one of the outside walls at the top matches the setting in your silcer - E-steps / rotation distance (X, Y, Z)
If the outside dimensions are not 20 mm but way off, correct the settings for the affected axis - Bridging / cooling
If the bridging perimeters in the top center are drooping/sagging, check cooling an bridging settings in your slicer - 45° overhangs
If the perimeters in this section are drooping/sagging, check the part cooling and cooling settings in your slicer - Speed / accelleration
ringing, bulged corners - you may want to reduce speed and/or accelleration (also see Preassure advance / linear advance) - First layer / bed adhesion
If there are problems with the print adhering to the bed, check if
- the bed is level and parallel to the x-axis
- the bed is clean - no dirt or grease
- the bed temperature is correct
If the print is wider at the bottom (first few layers) than at the top, check your z-offset and first layer settings - Retraction (stringing test)
If you experience stringing, check your retraction and cooling settings - Preassure advance / linear advance
If large seam gaps or bulged corners appear, consider tuning your printer firmware settings for preassure advance (Marlin) / linear advance (Klipper)
