Marlin Junction Deviation Calibration toolkit for Cura

thingiverse

THIS THING IS TOO PRELIMINARY TO BE USED AT THIS POINT! AS I GET INTO THE DETAILS AND MAKE IMPROVED TEST MODELS THAT WILL GIVE MORE CLEAR AND CONCLUSIVE RESULTS, I WILL UPDATE THIS THING... TILL THEN, FEEL FREE TO EXPERIMENT WITH WHAT IS PUBLISHED HERE AND SHARE YOUR EXPERIENCES! **NOTE: This tool is only useful when you have activated junction deviation in your firmware (#define JUNCTION_DEVIATION available in both bugfix-1.1.x and bugfix-2.0.x branches)** In order to successfully use junction deviation on current Marlin releases, it needs calibration and finetuning of this setting. I found it tedious doing multiple prints with different settings for junction deviation, so I created a model and Cura postprocessing script to help doing a test print for calibration using various values for junction deviation in a single model. The value will change over the course of the print, showing the effects of the values selected split over a series of sections (20 layers for each junction deviation value) on top of each other. Please read full instructions below before using! If you used this tool, please leave me a comment on your experience of using it and your results, so I can make improvements if needed.
