Set Speed
Sets the print speed for subsequent moves. The speed applies from this point onward until overridden by another Set Speed block.
Block

Parameters
value (mm/min)- Print speed in mm/min. 1800 mm/min = 30 mm/s. Accepts math expressions — use normZ to vary speed with height.
How it works
Set Speed controls the feed rate (F value) in the generated G-code. It affects all extrusion moves after this block until another Set Speed is encountered.
Common speeds
| Speed | mm/min | Typical use |
|---|---|---|
| Slow | 600–1200 | First layers, fine detail |
| Normal | 1800–2400 | Standard printing |
| Fast | 3000–4800 | Simple geometry, tall prints |
