Fans panel

Cooling control

Where More → Fans Controls 5

Two controllable fans (Part cooling + Chamber) get big interactive cards with ± buttons and preset pills. The row below shows the firmware-managed fans (Hotend fan, Controller fan, Pi cooling, MCU) read-only — you can see they're alive but can't accidentally fight the firmware.

Fans panel showing a Part Cooling card (75% running, presets 25/50/75/100) and a Chamber Fan card (off, 39°C / off target) on the top. Below them, a status row with four read-only firmware fans: Hotend Fan 100%, Controller Fan 62%, Raspberry Pi 42°/40%, MCU 38°.

Part Cooling card

Layer-cooling fan speed.

Set the part-cooling fan as a percent. ± steps in 10%, or tap a preset pill (Off / 25 / 50 / 75 / 100). Green border = fan is running. The slicer's commanded value at print start is the starting point; you can override it from here or from Fine Tune during a print.

2

Chamber Fan card

Enclosure heat target.

Sets the chamber fan's target temperature in °C — the fan modulates speed to hold the enclosure at that temperature. ± steps in 5°C. 'Off' means no target — the fan is idle. Useful for ASA / ABS to keep the chamber warm.

± controls

Adjust current value.

Big tap targets. For part cooling: −10% / +10%. For chamber: −5°C / +5°C. Hold to repeat-fire for fast adjustments.

Preset pills (Part Cooling)

One-tap speeds.

Off / 25 / 50 / 75 / 100 — quick jumps to common values. The currently-selected preset is shown in green. Tap any to set immediately.

5

Status row

Auto-managed firmware fans.

Hotend fan (heater-driven, keeps the heatbreak cool), Controller fan (mainboard cooling), Raspberry Pi (SBC cooling, shown with temperature + fan speed), and MCU (the toolhead board's local temperature). All read-only — the firmware manages them based on temperature.

Good to know

  • Part cooling is also adjustable live during a print from Fine Tune — values here vs. there are the same setting.
  • Chamber fan target is set in °C (not %); the fan modulates its own speed to hold the enclosure at that temperature.
  • If the Hotend or Controller fan shows 0% while the printer is hot, something's wrong — those fans should always run when the heater is on. Open a support ticket from the Info panel.
