Acceleration

Also known as: Print Acceleration

intermediate Slicer Settings ⚙️ Slicer Setting

How quickly the print head speeds up and slows down during movements.

Acceleration controls how quickly the print head changes speed. Higher values mean faster prints but can cause quality issues like ringing.

Typical Values

  • Conservative: 500-1000 mm/s²
  • Standard: 1000-3000 mm/s²
  • Fast: 3000-10000 mm/s²
  • Speed printers: 10000-20000+ mm/s²

Effects

Too High

  • Ringing/ghosting artifacts
  • Layer shifts
  • Motor skipping

Too Low

  • Unnecessarily slow prints
  • Doesn’t reach target speeds on short moves

Input Shaping

Modern firmware (Klipper) uses input shaping to allow very high acceleration without ringing artifacts.
