Does Anyone Know if the K1 Max can turn itself off after printing?

You can use a wifi power plug such as TPlink. You will have to root your K1 and install moonraker to set a macro to control the tplink plug.

in moonraker.conf add

[power printer]

type: tplink_smartplug

address: 192.168.0.172 'insert the IP address of the tplink plug

restart_klipper_when_powered: True

restart_delay: 3

port: 9999

in gcode_macro_cfg ADD

[gcode_macro POWER_OFF_PRINTER]
gcode:

{action_call_remote_method(“set_device_power”,
device=“printer”,
state=“off”)}

[delayed_gcode delayed_printer_off]
initial_duration: 0.

gcode:
POWER_OFF_PRINTER

Modify END_PRINT macro: Add last line.

[gcode_macro END_PRINT]
