19. Filament calibration
Revotech filaments come with ready, tested settings. Calibrate your own filament in Orca Slicer (the Calibration menu). Start with dry filament and a suitable temperature, run the tests in this order and save each result in the filament profile.
- Temperature – Calibration → Temperature: a temperature tower. Pick the segment with the best bridges, overhangs and surface, without strings.
- Flow rate – Pass 1, optionally Pass 2. Pick the smoothest block. New flow = current × (100 + correction) / 100.
- Pressure advance – line method (fast) or tower (more accurate). Pick the line with the most even width. Typical for direct drive: PLA 0.02–0.06, PETG 0.04–0.10, TPU 0.08–0.30. Each material has its own value.
- Retraction – the smallest value at which strings disappear. If strings stay despite large retraction, dry the filament and lower the temperature by 5°C.
- Max flowrate – read where the surface starts to break down and enter 10–20% less. The neXtG UHF hotend passes up to about 45 mm³/s (0.8–1.2 nozzles).
Input shaper (frame vibration) is set by Revotech service at handover – no need to repeat it. Want a ready profile for your material? We will set it up for you.
