Hello! I made a software for Cura that allows you to combine different G-code files into one. It might come handy if you want to test different settings on your printer on one print (like test towers). With G-code Combiner you can choose which files will be used on which layers of the print. I also added a function to use custom g-code before files and after executing them. Cura has option to change settings on layer basis with support blocker but not for all settings available in the slicer. Feel free to share your thoughts about my software and please report issues if they occur so I can fix them. Here's a link to G-code Combiner: https://github.com/rara64/gcombiner Thanks!
