Services

Sources of Makerbase services

  • The files below have been collected (and repackaged) from the original Sovol KlipperScreen images
  • The MS1987/SOVOLMKDEB repository seem to be the source of the original packages
    (thanks to nubecoder for investigation)

makerbase-auto-fresh.service

  • Installs system updates
  • Files: makerbase-auto-fresh-files
  • Unofficial package: makerbase-auto-fresh-service.deb
  • Details:
    • if existing: install /root/system_deb/*.deb and reboot
    • if existing: install /root/bootsplash.armbian and reboot
    • if USB drive found:
      • ensure running automounter (mounts to ./printer_data/gcodes/USB)
      • move armbian-update.deb from automount to /home/mks, then install and reboot
  • Depends on makerbase-automount@.service
  • Might become useful once there is an unbricking-package like Sovol's armbian-update.deb

makerbase-automount@.service

makerbase-beep.service

  • Beeps if touchscreen is touched
  • Files: makerbase-beep-files
  • Unofficial package: makerbase-beep-service.deb
  • Details:
    • initializes GPIO#82 (beeper pin)
    • reads events from touchscreen (with vendor_product_id=*1a86*e5e3*)
    • beeps if touch-button got pressed
  • Useful

makerbase-byid.service

makerbase-net-mods.service

makerbase-soft-shutdown.service

  • looks disabled
  • does something with the "supper" capacitor
  • Files: makerbase-soft-shutdown-files
  • Unofficial package: makerbase-soft-shutdown-service.deb
  • Unsure, if it is useful:
    It writes "0" to gpio100 at boot time (whatever that does) and then syncs the filesystem every 2 seconds. The syncing might be of some use, if the device is not shut down before cutting the power.

makerbase-timezone-monitor.service

makerbase-wlan0.service

power loss recovery (plr)

Reverting

power loss recovery (plr)

  1. Make a backup of printer.cfg!
  2. Edit printer.cfg, find and remove the 3 paragraphs shown below.
  3. Test the new config: Do a normal print with normal end. And then cancel a print.
  4. If there are errors, revert to your backed-up printer.cfg
  5. If everything is fine, log in via ssh/putty and remove the unused files: "rm ~/plr.sh ~/clear_plr.sh ~/printer_data/config/plr.cfg"

#1: Somewhere at the beginning:

[include plr.cfg]

#2: At the start of "[gcode_macro CANCEL_PRINT]", after "gcode:":

    SAVE_VARIABLE VARIABLE=was_interrupted VALUE=False
    RUN_SHELL_COMMAND CMD=clear_plr
    clear_last_file
    G31

#3: Before the "SAVE_CONFIG" section:

[gcode_macro PRINT_START]
gcode:
    SAVE_VARIABLE VARIABLE=was_interrupted VALUE=True
[gcode_macro PRINT_END]
gcode:
    SAVE_VARIABLE VARIABLE=was_interrupted VALUE=False
    RUN_SHELL_COMMAND CMD=clear_plr
    clear_last_file
