Touchscreen

Everything is reached from the home screen, and every page has a back button to it. There is no menu tree to get lost in.

Home

Live readings, and six buttons to the pages above. Temperature, humidity, air quality and filament weight are all here.

Sensor readings keep updating in the background whichever page you are on, so the safety responses and the log do not depend on where you left the screen.

Fan Control

Control	Does
Filter AUTO	Fan follows air quality
Filter MANUAL and slider	You set the speed
Cooling AUTO	Fan follows temperature
Cooling MANUAL and slider	You set the speed
Extra fan	On and off. Speed comes from `extraFanSpeed`
OPEN and CLOSE	Moves the duct flap

Auto and manual are mutually exclusive per fan. Moving a slider switches that fan to manual, and pressing AUTO clears manual. The two fans are independent, so one can be automatic while the other is not.

The OPEN and CLOSE button is the only servo control. There used to be a position slider on the Output Control page, and it is now dead on purpose. Set the two end positions with servoOpenAngle and servoCloseAngle in data.clu instead.

The flap position is remembered across power cycles. Safety overrides can move it, as covered in Safety Systems.

Spool Holders

Four spools per page, with arrows to page through your library. Tick one box on the left column and one on the right, for the two holders.

Two buttons take you out of this page:

Calibrate, for load cell calibration, the one you do once
Custom spool, for registering a new brand

The weight shown is net filament weight, meaning the measured weight minus the selected spool’s empty weight. With nothing on the holder it reads as a negative number, specifically the negative of the tare weight. That is correct.

Sensors

Raw sensor readings, plus the logging controls:

Logging on and off
Interval, which cycles through 5 min, 10 min and 60 min
Format, which deletes log.csv and starts fresh

This page is the right place to watch raw gas and smoke values before changing an alarm threshold.

Lighting

Colour and brightness for the WS2812B strip, seven preset buttons, and the LED bar switch.

Brightness is a multiplier on the colour, so a dim red and a bright red are the same preset at different brightness values.

The strip turns red when the smoke or gas alarm triggers, overriding whatever you have set. It goes back to your colour once the sensors read clear.

Output Control

LED bar, which is the same switch as on the Lighting page
Relay, for the solid state relay output
Auto servo, for automatic flap control
Servo power, which affects auto mode only

The servo position slider on this page does nothing. See the note under Fan Control.

Settings

Control	Notes
Brightness	Floored at `minBrightness`, which is 15 by default, so the screen never goes fully dark
Standby	Minutes of no touch before the screen switches off
Set baseline	Currently has no effect. It stores a temperature and gas reference that nothing reads yet
Mute	Silences the buzzer only
Alarm LED	Turns off the red alarm lighting only
Reset usage counter	Clears the filter runtime counter
Restart	Reboots the mainboard
Configuration	Runs the first setup again
Support	Contact information

Mute and the alarm LED toggle do not touch the fan cutoff or the flap. Silencing a nuisance alarm can never disable the actual safety response. See Safety.

Standby

After the standby time with no touch, the screen switches off. Your settings are saved to the mainboard’s memory at that moment, which is a useful side effect: letting the screen sleep before you unplug is a good habit.

Touching the screen wakes it.
