revert qidi software

this script is for the max3/plus3/smart3. it will revert your klipper and moonraker to working versions from qidi's repository, and it will install the latest working version of fluidd

using a terminal client such as putty for windows, Terminal on macos or linux, or an app like shelly or terminus on your phone, ssh into your printer: ssh mks@printer.ip.address replacing 'printer.ip.address' with your printers ip address. the username is 'mks' and the password is 'makerbase' (for ssh and sudo) any time you are prompted for a password (unless you changed it)

if you get an ssl certificate error downloading the script, or if you have to reinstall klipper/moonraker (steps 4-5), you need to make sure your date and time is correct. ssh into your printer and run date. if the date is incorrect, find your time zone here: https://en.m.wikipedia.org/wiki/List_of_tz_database_time_zones (it should be in the format America/Chicago), then run sudo timedatectl set-timezone [your_timezone] ; sudo timedatectl set-ntp 1 replacing [your_timezone] with your actual timezone. run date again and make sure its correct. if its not, follow the steps here to fix it before proceeding: https://wiki.qidi3d.com/en/Memo/System-Time-Modification

download and run the recovery script

1. run cd ~ ; wget --no-check-certificate https://raw.githubusercontent.com/billkenney/revert_qidi_software/main/revert.sh ; chmod +x revert.sh ; ./revert.sh

2. the script shouldn't take long, maybe around a minute depending on your internet connection. once its done, turn your printer off and on and you should be good to go

3. after rebooting your printer, if its not working, run sudo service klipper status and make sure it does not say 'failed', 'exited', service not found, or any other error code. also run sudo service moonraker status and make sure it does not say 'failed', 'exited', service not found, or any other error code

if klipper or moonraker is not working after running the script

4. if klipper is not working properly after running the script, run chmod +x /home/mks/klipper/scripts/install-debian.sh ; /home/mks/klipper/scripts/install-debian.sh. after the install is finished, check to make sure the service is working properly sudo service klipper status

5. if moonraker is not working properly, run chmod +x /home/mks/moonraker/scripts/install-moonraker.sh ; /home/mks/moonraker/scripts/install-moonraker.sh. after the install is finished, check to make sure the service is working properly sudo service moonraker status

if the printer or screen are still not working, reinstall the firmware, or write a recovery image to the emmc

6. follow the steps here to reinstall the firmware: https://github.com/billkenney/qidi_3series_recovery/blob/main/README.md

7. if it still doesn't work, you may need a new emmc, contact qidi support about this. if you already have an emmc adapter, follow these instructions to write the recovery image to your emmc: https://wiki.qidi3d.com/en/Memo/flash-emmc. update the firmware after booting with the newly flashed image (step 6)

write the xindi recovery image to your existing emmc without an adapter

8. someone posted that you can write the xindi image to a flash drive, plug it into the motherboard, and it will boot from the flash drive instead of the emmc. if you are able to do this, you can write the xindi image to your emmc without an adapter. first copy the xindi image file to a second flash drive and plug that into your printer, ssh into the printer, and check the path to the second flash drive with sudo lsblk, mount it, and write the image to your emmc module. first check that '/dev/mmcblk0' or '/dev/mmcblk1' is in the list of hard drives, this is your emmc. the second flash drive will probably be '/dev/sdb1', in which case you run sudo umount /dev/sdb1 ; sudo mount /dev/sdb1 /mnt. check to make sure the xindi image is there: ls /mnt, this should return 'xindi-20230309.img'. if the image is there, run sudo dd if=/mnt/xindi-20230309.img of=/dev/mmcblk0 bs=32M status=progress. replace '/dev/mmcblk0' with the path to your emmc

you need to update your firmware and install the correct printer.cfg after writing the xindi image to your emmc. follow these steps to reinstall the firmware and update the printer.cfg: https://github.com/billkenney/qidi_3series_recovery
