Calibration Tools

If you are using the Ultimaker Cura installed at Makersmiths the Calibration Shapes plugin by 5axes is installed.

Printing a Temperature Tower

Printing a temperature tower helps you find the right temperature to use for printing for a specific spool

You can use one of the temperature towers from the Part for Calibration plugin or you can find one on your favorite model site.

Temperature towers tend to test more than one thing, typically temperature, overhang, and bridging.  In this model, you can see red under the bridges and on the overhangs.  A properly tuned printer and filament should be able to handle those with no supports.

On the left side of the model you will see temperature numbers starting at 220 and decreasing by 5 on each new segment until reaching 180.  This is the typical range for PLA.  There are other temperature towers for other materials.


Slice your tower and go to preview mode



Using the slider on the right side of the screen, find the point at which the first section of the tower ends and the second section begins.  Make note of the layer number


Now, select Extensions > Post Processing > Modify G-Code


Click  "Add a script" and select "TempFanTower"


In the "Change Layer" box type in the level you found for the change.

Starting Temperature - What temperature to start the process at (your first section)

Temperature Increment - How much to change the temperature with each iteration.  Number can be positive or negative

Change Layer - How many layers to remain at that temperature before changing

Change Layer Offset - This defines the base of your print.  For this number of layers, the print will be at the temperature defined in the print settings under Material.

Activate Fan Tower - This is for testing the effect of different fan speeds.  Do not check this box for a normal temperature tower test


Click Close when finished


Reslice your model to incorporate the script into the G-code.



Save your code to a file and then print on your chosen printer.

After you save your G-Code file, go back to the Extensions > Post Processing > Modify G-Code menu and delete the TempFanTower script.

Leave the Create Thumbnail and Display Layer scripts

Printing a Calibration Cube

Calibration cubes are used to help fine tune the motors for the X, Y, & Z axes to deliver accurate and precise prints.

You can use the Calibration Cube from the Part for Calibration plugin or you can find one on your favorite model site.
