Customizable Temperature Calibration Tower

thingiverse

I took the source project by kerog777 and modified the python file to work with the new Cura version (3.0 and up I believe). I figured I'd just release my own set of instructions for this as well. This comes with an STL file to test temperature from 240 down to 195, but if you want to modify that range, you can edit the included OpenSCAD file and adjust the "BottomTemperature", "TowerHeight", "HeightIncrement", and "TemperatureIncrement" variables, and then render them down to another STL file. Once you have an STL file of your choosing, you must add the included python file "VaryTempWithHeight.py" in to Cura's post processing scripts folders. These can be found in the folder that Cura exists in once it is installed. For me it was in "C:\Program Files\Ultimaker Cura 3.0\plugins\PostProcessingPlugin\scripts\". Once the script is in there, you must restart Cura (if it was already open). Now once you have Cura open, load in your STL file. Set the temperature to the high temperature that you have set in your model, as the script will not set the temperature at the very beginning. In the menu bar go to "Extensions -> Post Processing -> Modify G-Code". Clicking on that will open up a new window for post processing scripts. Click on the "Add a script" button and choose "Vary Temp With Height". This will show you some variables on the right side of the box. Make sure you set them the same way you set the OpenSCAD file that rendered your STL file. In the case of the example STL file it would be 240 Start Temperature, 5 Temperature Increment, and 10 Height Increment. Click on close, and Save your G-Code to file. Now when this prints, the printer will change temperatures at every 10 mm's. If you want to double check your G-Code to make sure the extra commands were inserted, you can open the G-Code up in Notepad and look for the word "CUSTOM". If It is there, then the script worked. If you have any questions, please don't hesitate to ask. Note: I didn't print the test STL file in this, but I have supplied a picture of one I printed with slightly different values. p.s. Credit goes to kerog777 for the OpenSCAD file, as well as the original idea and python script.
