Commands

Type these in the Mainsail or Fluidd console, or put them in your slicer's G-code. Run the ones that move the printer only when it is not printing, except AUTO_EJECT in the end G-code.

Everyday

Command	What it does
AUTO_EJECT	Cool the bed, push the parts off, check the bed with the probe. Put it in the slicer's end G-code
AUTO_EJECT HEIGHT=[max_layer_z]	The same, with the print height from the slicer, so flat prints are recognised and left alone
AUTO_EJECT HOME=1	Home safely around the parts first if the printer is not homed (after the end macro turned the motors off, a restart or a power cut), then eject
AUTO_EJECT DRY=1	Trace the path 2 cm above the bed without pushing, cooling or probing
AUTO_EJECT_CLEAR	You took the parts off by hand: forget them, the bed is clear. While the bed cools with the printer free, it also stops the eject; the job queue waits for AUTO_EJECT_CONTINUE
AUTO_EJECT_PUSH_NOW	While the bed cools with the printer free (cool_background), push the parts off now instead of waiting (how)
AUTO_EJECT_BIN_EMPTY	You emptied the parts box: count from zero again (the parts box)
AUTO_EJECT_NOTIFY_TEST	Send a test notification to your phone, through the app's notification service and the notify notifier, whichever are set up (notifications.md)
AUTO_EJECT_CONTINUE	You took flat prints off by hand: close the dialog and start the job queue again

Setup

Command	What it does
AUTO_EJECT_SETUP	The guided setup, in dialogs (setup-wizard.md)
AUTO_EJECT_CALIBRATE	Measure the blade again with a nozzle probe (Voron Tap), for example after moving it
AUTO_EJECT_SET KEY=cool_temp VALUE=35	Change one setting and keep it after a restart (configuration.md)
AUTO_EJECT_SET KEY=cool_temp RESET=1	Go back to the value in auto_eject_settings.cfg
AUTO_EJECT_SET KEY=enabled VALUE=off	Switch auto-eject off: each print's parts stay on the bed and the queue waits. VALUE=on switches it back on (configuration.md)
AUTO_EJECT_SETUP STEP=reset	Forget every value saved by the setup and AUTO_EJECT_SET

In the slicer's start G-code

Command	What it does
AUTO_EJECT_GUARD	First line of the start G-code: stops the print if parts from an earlier print may still be on the bed (recovery.md). With DEMON, AUTO_EJECT_GUARD FROM=DEMON in its _CUSTOM_PRE_START hook (integration.md)
EJECT_PURGE	After your start macro: purge a tall blob the blade can push off, instead of a thin line (integration.md)
EJECT_PURGE X=200 Y=60	The same, at a fixed spot

Options for one run

These can be combined, for example AUTO_EJECT HOME=1 COOL=0.

Option	What it does
STRATEGY=columns, objects or full_width	Use another path strategy this time (strategies.md)
COOL=0	Do not wait for the bed to cool
VERIFY=0	Do not check the bed with the probe afterwards
SOURCE=saved	Eject the parts remembered from before a restart (used with HOME=1)
HEIGHT=12.4	The print's height in mm
