Klipper Configuration files for Gigabot 3D-Printers

Gigabot Touchscreen

The Gigabot Touchscreen is built ontop of FullPageOS This CustomPiOS is a Raspbian image that displays a chromium webpage in full screen mode.

This repository is used to install additional OS dependencies and repositories to install the Klipper software stack ontop of FullPageOS.

Easy Install From Release Image

Download the latest release package in releases and follow the instructions in the attached pdf.

Manual Installation

  1. Flash a SD card with FullPageOS using the Raspberry Pi Imager (Other specific purpose OS)
  2. Input the flashed image into a raspberry pi, and ssh into the pi
  3. Run git clone --branch main https://github.com/Mitchell-Mashburn/klipper_config
  4. Run sudo ./src/system_config/install.sh. Wait for the installation to finish
  5. Run sudo apt update
  6. Run sudo apt upgrade

Flashing Firmware

  1. Navigate to the kiauh folder cd kiauh
  2. run ./kiauh.sh
  3. option 4 - advanced
  4. build + flash
  5. due/duet2, Sam3x8e - q to exit, save changes
  6. regular flashing method
  7. USB

More Details

As stated above, there are many Fullpageos_modifications specific to getting the raspberry pi to display its interface on the HMTech Display.

apt-get Dependencies ontop of FullpageOS:

xinput ripgrep nmap

Other system level configurations are as

Disable Scrollbar

Add --enable-features=OverlayScrollbar to starting chromium script, ~/scripts/start_chromium_browser

Disable Cursor

Append xserver-command=X -nocursor to /usr/share/lightdm/lightdm.conf.d/01_debian.conf

Add Keyboard Extension to Chromium

Copy .config to home directory of pi

Enable full kms graphics driver

Append dtoverlay=vc4-kms-v3d to /boot/config.txt

Adjust screen resolution permenantly

Upload xrandr/ script file, and add lightdm.conf to /etc/lightdm/lightdm.conf Move lightdm.conf to /etc/lightdm/

Allow for screen rotations

Install xinput with sudo apt install xinput enable full kms driver, and run ~/scripts/rotate.sh left

Disable boot text

Upload cmdline.txt to /boot/

Troubleshooting

Get lightdm service status journalctl -u lightdm.service

Recording with autoexpect

autoexpect -p ./kiauh/kiauh.sh

Building an Image

Below is the guide on creating a customized image of the OS to flash as bootable media.

1. Shrinking partion on Raspberry Pi

  1. Put the SD you want to copy into a card reader and connect to a usb port on the pi.
  2. Use a standard raspbian OS on a different SD and boot into it.
  3. Install gparted on the raspberry pi sudo apt-get install gparted -y
  4. Launch gparted from the raspbian OS GUI, in system tools.
  5. Select the external SD from the pull down menu in the upper right corner.
  6. Unmount the rootfs partition if it is mounted (a key icon next to it) by right clicking it and selecting unmount. If it is grayed out, then it is not mounted.
  7. Right click rootfs and select resize/move.
  8. Select the new size for the partition. Resize to atleast the minimum or slightly larger.
  9. Click the green check mark at the top and click apply to proceed.
  10. Shutdown the pi.
  11. Now insert the SD you want to copy in to boot from.

2. Creating the Disk Image

  1. Have a formatted USB or similiar media to copy the image onto and insert into the pi.
  2. Check the mount point of your USB by running lsblk
  3. You should see something like sda1 with a mountpoint on /media/pi/usb.
  4. If you see that there is no mountpoint try rebooting with the USB connected and check again.
  5. If there is still no mountpoint, then mount it manually by running sudo mkdir /dev/myusb to create a directory then sudo mount /dev/sda1 /dev/myusb to mount it.
  6. Using dd, copy all the data to an img file similiar to this: sudo dd if=/dev/mmcblk0 of=[mount point]/copy.img bs=1M count=6500 status=progress
  7. bs=1M means using megabytes and count=6500 * 1M = 6.5 GB of data it will copy. It's always good to copy more data that you use by a few hundred megabytes.

3. Compressing the image

  1. Install pishrink.sh and copy it to the /usr/local/bin by running:
  2. wget https://raw.githubusercontent.com/Drewsif/PiShrink/master/pishrink.sh
  3. sudo chmod +x pishrink.sh
  4. sudo mv pishrink.sh /usr/local/bin
  5. Navigate to the USB drives root directory cd /dev/myusb
  6. Use pishrink with the -z parameter to compress your image sudo pishrink.sh -z copy.img

Happy Printing! :)
