Guides

• Bed adhesion: what actually works
  Glue sticks, hairspray, rafts, brims and expensive surfaces — an honest ranking of what fixes prints coming loose, starting with the free fix that solves most cases.
• Do you need a filament dryer?
  Wet filament is real and ruins prints, but a dedicated dryer is not the only answer. How to tell if moisture is your problem, and what to do about it.
• Filament storage: dry boxes, vacuum bags and desiccant
  Keeping filament dry is cheaper than drying it out. What actually works, what desiccant to use, and why the little sachet in the bag is already spent.
• First layer calibration, properly
  Nearly every adhesion problem and half of all print failures start in the first layer. How to set Z offset by eye, and what a good first layer actually looks like.
