• 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

• Mounts all storage devices/partitions under /home/mks/printer_data/gcodes/USB/
• Files: makerbase-automount-files
• Unofficial package: makerbase-automount-service.deb
• Useful for those who want to have USB-drives automatically mounted as gcode storage

• 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

• Updates serial: from section [mcu] in home/mks/printer_data/config/printer.cfg
• Files: makerbase-byid-files
• Unofficial package: makerbase-byid-service.deb
• Probably useless, the name of the serial connection doesn't change

• copies /boot/wpa_supplicant-wlan0.conf (if existing) into /etc/wpa_supplicant/
• Files: makerbase-net-mods-files
• Unofficial package: makerbase-net-mods-service.deb
• Probably useless, you can configure wifi on the screen

• looks disabled
• does something with the “supper” capacitor
• Files: makerbase-soft-shutdown-files
• Unofficial package: makerbase-soft-shutdown-service.deb
• Useless

• Fetches time via NTP every 3 seconds (spamming syslog)
• Update timezone to that from /home/mks/target_timezone.txt
• Files: makerbase-timezone-monitor-files
• Unofficial package: makerbase-timezone-monitor-service.deb
• requires /home/mks/target_timezone.txt
• Probably useless, works fine without

• configures wpa_supplicant
• Files: makerbase-wlan0-files
• Unofficial package: makerbase-wlan0-service.deb
• Probably useless, works fine without

• resumes print after power failure
• origin: https://github.com/The--Captain/plr-klipper
• Used files:
  • ~/printer_data/config/plr.cfg
  • ~/plr.sh
  • ~/clear_plr.sh
• Unofficial package: plr-klipper.deb
• Included in Sovol's default printer.cfg, thus it's recommended

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
