I have 2 ender 3s, and they were awesome. I learned so much about engineering, gcode, and flashing firmware. I spent so much time fine tuning print parameters and installing mods, and I was able to get decent prints. I moved and picked up a bambu P1S, during a black Friday sale a few years ago. My enders are still packed and my P1S has just worked, giving me prints quality and consistency I only could have dreamed of using my enders. Now, I just need a project to recycle my enders parts into.
Long story short, use teaching tech ender 3 calibration guide, dry your filament, and install auto bed leveling probe that will account for warped build plates. https://teachingtechyt.github.io/calibration.html











Unfortunately you don’t really have a choice. Organic and GMO free doesn’t mean herbicide free, and plants with natural tolerance to herbicides either have genes to detoxify or sequester them in their cell walls. If the sequester them, then you get to eat nice bioaccumulation of herbicide. Glyphosate itself is pretty safe mechanistically, however everyone forgets about the adjuvants its formulation.
