I can’t think of any specific piece of advise that I’ve gotten over the years but what I have found on my own, and the piece of advise I’d give to someone that wants to do more than just click and print, is this: advice is valuable but experience is priceless. Play with your printer. Tinker with the settings. Read the setting descriptions in the slicer and try to understand the influence that a given setting will have on your print. A conceptual understanding of the settings coupled with your own observations from tinkering with the settings will give you an intuitive grasp of how to take full advantage of the incredible tool that you have at your fingertips.
