Production Tips

  1. First layer calibration: Run Prusa’s built-in V2Calibration gcode for automatic first-layer optimization
  2. Sheet management: Alternate between two PEI sheets — one cooling while the other prints
  3. OctoPrint integration: Remote monitoring and print queuing for batch production
  4. Filament sensor: Enable the filament runout sensor for unattended printing

Individual results depend on your printer, environment and application.
