Adding restart/shutdown commands in OctoPrint’s menu.

In this case, I have replaced the Raspberry Pi with an OrangePi Zero. Usually, the host is replaced with a Raspberry Pi, connected to LAN or WLAN and running an Octoprint instance. Octoprint is an open-source project which is intended to allow 3D printing without a host (regular PC) connected to the printer. To have the WEB interface, the printer is connected to its own WEB server which has Octoprint running on a small OrangePi Zero Linux computer. WantedBy=sys-subsystem-net-devices-wlan0.I have started modifying my own 3D printer and one of the mods is a WEB interface. Create a Unit file with: rpi ~$ sudo systemctl -full -force edit the empty editor insert these statements, save them and quit the editor: Īfter=viceĮxecStart=/sbin/iw dev wlan0 set power_save %i I will give you here a bit more comfortable example for switching off or on power_save. To execute programs on boot up you can use a systemd Unit file. If you do not have an on-board WiFi and using an USB/WiFi dongle then you will not find brcmfmac because there is another driver loaded for the dongle. Update after getting information about used hardware: You will find it if you grep the journal for the driver: rpi ~$ journalctl | grep brcmfmac:Īpr 14 22:13:28 raspberrypi kernel: brcmfmac: F1 signature read 14 22:13:28 raspberrypi kernel: brcmfmac: brcmf_fw_map_chip_to_name: using brcm/brcmfmac43455-sdio.bin for chip 0x004345(17221) rev 0x000006Īpr 14 22:13:28 raspberrypi kernel: brcmfmac: brcmf_c_preinit_dcmds: Firmware version = wl0: 03:15:32 version 7.45.154 (r684107 CY) FWID 01-4fbe0b04Īpr 14 22:13:28 raspberrypi kernel: brcmfmac: brcmf_c_preinit_dcmds: CLM version = API: 12.2 Data: 9.10.105 Compiler: 1.29.4 ClmImport: 1.36.3 Creation: 18:56:28Īpr 17 09:01:27 raspberrypi kernel: brcmfmac: power management disabledĪs you see, it is power management disabled.

Now it is disabled by default with the WiFi driver brcmfmac. Power save mode was an issue years ago on older versions of Raspbian.
