Recommended Safety Equipment

  • Beware of Pinch Points.
  • The heated bed gets hot.
  • The nozzle gets hot too.

Prior to each use


  • X and Y belts are taut
  • Filament loaded properly
  • Print surface prepped: (PET with ABS solution for ABS printing/Bare glass for PLA/Garolite or cellulose based material for Nylon)
  • Home all axes prior to using the manual movement controls

After each use


  • Clean bed of any left over filament.
  • If using personal filament reload the space filament and prime the nozzle by bringing it to temp and verifying extrusion.
  • Home all axes
  • Power off the printer using the power switch on the left hand side of the printer (for now)


Please leave a donation for any printer use. Filament costs on average $50 a kg (2.2lb) with shipping. Please leave a dollar or two for each hour the print takes. You can donate by giving cash to a board member, with paypal or with purchasing filament. Make a donation now. Please purchase reels for ease of use and stability. Coiled filament will work but can be a pain.
