Printing Guidelines

  • Ensure the track top faces towards the print bed
  • Utilize a textured sheet for better adhesion
  • Suitable printing materials: PLA or PETG
  • Use light supports or no supports
  • Consider adding “elephant ears” (small circular tabs) at the ends to prevent lifting and improve first-layer adhesion and heating the bed more than usual.
