Dialing in printer settings

Note

These notes apply to the Prusa i3 Mk3 printer. If you are using a different printer, please verify the hardware details are same. These pages may be a bit rough as I revise them and add new material. Please check back regularly for updates.

Dialing in printer settings

Most of these print in 15-30 minutes, so are far better suited for an afternoon of calibration.

I personally hate benchy, so have a miniature I print that ranges from 1-3 hours depending on settings. This is my confidence check when trying out new slicer profiles.

First layer calibration

See Live-Z calibration procedure.

Printer calibration

  • ECOR tower
  • Extruder calibration
  • PINDA
  • Temperature

Filament calibration

  • Linear advance
  • Calibration cubes
  • Extrusion multiplier
  • Temperature tower

Dimensional accuracy

A print of a humble 20mm cube is one of the best tools to test basic calibration:

  • Sliced with your normal slicer settings, it’s a good test for overall finish, comparing effects of layer height, z-seam alignment and overall dimensional accuracy.
  • Sliced with a single external perimeter set to exactly nozzle size, 0 infill and 0 top layers, it provides a good test of dimensional accuracy and extrusion width.
  • Platform stability
  • Belt tension

Contact and feedback

You can find me on the Prusa forums or Reddit where I lurk in many of the 3D printing-related subreddits.
