Parameters
value (%)- Fan speed 0-100%. 0 turns fan off. Accepts math expressions.
How it works
Set Fan controls the part cooling fan in the generated G-code. At 0%, the fan is turned off (M107). For values 1-100%, the block outputs M106 S{0-255} where the S value is scaled from the percentage.
G-code output
| Value | G-code | Behavior |
|---|---|---|
| 0% | M107 | Fan off |
| 1-100% | M106 S{0-255} | Fan at scaled speed |
