Cura Lift Head at Z for PETG Print Gap Plugin

thingiverse

They say that PETG prefers to "settle in" and not be "crushed down" like other materials. After the first layer, you should elevate the print head slightly so there's a gap between the nozzle and the printed piece. This add-on will enable you to do it in Cura. To use it: Place it in your <cura 3x>/plugins/PostProcessingPlugin/scripts directory. You'll need to restart Cura. Go to the Extensions menu, then Post-Processing and Modify G Code. There, you'll be able to select the add-on. The height should be set higher than your first layer height but lower than your second. This code was adapted from BQ_PauseAtHeight.py plugin. Thingiverse requires a valid STL or design file for submission, so I uploaded a test shape that I use to test new materials. Have fun! I've tested this on Cura 3.0.3.
