Use XYZ Calibration Cube to Detect 3D Printing Issues and Tune Your 3D Printer

Calibration cube is an easy object to print and can be used widely to detect various problems in 3D printing and to tune your 3D printer.

As we can see in above picture, elephant foot is happening on the first layer of the right print of the XYZ calibration cube. Then we can go to elephant foot 3D printing trouble shooting guide and tune your 3D printer to solve the problem

The 20mm XYZ calibration cube is a classic design for tuning your 3D printer. Sometimes when we find a problem in our 3D prints, it’s difficult for us to pinpoint the problem out. But if we print the XYZ calibration cube, we can quick detect problems and narrow down to exact axles, such as a Z wobbling, bottom layer bulging, loose belt, or any other problems.

Below are some common symptoms happen when we print the calibration cube and methods to tune your 3D printer.

1. 3D Printing Ghosting / Ringing

3D printing ghosting or ringing is often caused by vibration. And vibration might be caused by loose belt, fast printing or unstable base. Thus the solutions are tightening the belts of your 3D printer, slowing down printing speed and placing your 3D printer at a solid table.

2. Z Wobbling

Z wobbling is the layers not aligned well with the neighboring layers above and below and form layer bands.

Methods to cope with z wobbling:

  1. Correctly align the Z axis
  2. Use half or full step layer heights
  3. Enable a consistent bed temperature
  4. Stabilize Z axis rods
  5. Stabilize bearings and rails in other axis/print bed

3. Bottom Layer Bulging

Bottom layer bulging is commonly named as elephant foot 3D printing. The bottom layer of your print extrudes like an elephant foot.

Solutions for elephant foot 3D printing:

  1. Level your 3D printer and adjust nozzle height from the bed
  2. Lower bed temperature to increase bottom layer cooling speed
  3. Always print with a raft
  4. Add chamfers to some specific models

4. XYZ steps per millimeter adjusting

The steps per millimeter number can affect print accuracy on each axle of 3D printing. By measuring the size of a printed 20mm XYZ calibration cube, we can decide how to adjust these numbers.

As we can see in above image, the number is 19.74mm, a little lower than 20mm. So we can adjust the steps per millimeter number up accordingly on the corresponding axis. If the measured number is higher than 20mm, then we do the opposite.

Print a 20mm XYZ calibration cube is quite helpful for adjusting your 3D printer to perform well in daily printing. We strongly recommend you to have try on it if you find any printing issues while using an Anet 3D printer.
