Here you will find several ways to log into the KlipperScreen.

• Allows access even in bootloader stage
• Requirements:
  • USB-C cable
  • Terminal software (e.g. putty)
• Instructions:
  • Power on the KlipperScreen
  • Find the com-port in the device manager:
    • On the PC press the “Windows”-key together with the “R” key.
    • In the newly opened window, enter “devmgmt.msc”. This opens the device manager.
    • Look for the section with “COM & LPT” and expand it.
    • Now connect the USB-C cable to the KlipperScreen and the PC.
    • A new entry should pop up “USB-SERIAL CH340 (COM*)” (the “*” can be any number)
    • The name in brackets is what you have to enter in putty (e.g. “COM3”)
  • Download and start putty
  • Configure the com-port in putty:
    • Select “Serial” (quite at the top, below “Connection type:”)
    • Enter the name of the com-port (e.g. “COM3”, check the previous step for the correct name)
    • Set “Speed” to “1500000” (that's 5 zeroes after the “15”)
    • Select “Open”
    • This should open a terminal window
  • In the terminal window press Enter, a new line should appear: mkspi login:
  • Enter the name and the password:
    • The default name is mks
    • The default password is makerbase
  • Congrats, you are logged in.

• Instructions for entering bootloader:
  • If possible, first try to get the serial connection working as shown above. Entering the bootloader is a bit more difficult and time-critical, so it's good if you already familiarized with that and know, that you have a working serial setup.
  • Enter correct power off state:
    • The KlipperScreen has to be shut-down, but still connected to the power. (If it has no power, the com-port will not exist, and you won't be able to connect to it fast enough to intercept the boot process.)
    • Clean ways to get the KlipperScreen into power-off mode are e.g. a) using the shutdown buttons on the screen of the KlipperScreen b) performing a sudo poweroff or sudo halt when logged in via serial or SSH
    • A more unclean way is keeping the small power-button on the side pressed for about 10 seconds.
    • In the correct powered off state, the LEDs at the top are off. But you can see a blue LED inside the case when watching through the airholes.
  • Intercept the bootloader:
    • Connect the USB-C cable, start putty and connect to the com-port as shown above
    • Activate the terminal window and keep the spacebar pressed until told otherwise
    • Press the small powerbutton on the side of the KlipperScreen for about 1-2 seconds
    • There should appear a line reading Hit any key to stop autoboot: 0.
    • When you see the spaces arriving on the screen, you stop pressing the spacebar.
  • Voilà, you're in the bootloader menu, do what you've been told to do there ;) E.g.:
    • Enter run bootcmd_usb0 to enter from USB-drive
    • Enter boot to continue normal booting
    • Enter help for a list of supported commands.

• Requirements:
  • USB-keyboard
  • Working display on the KlipperScreen
• Instructions:
  • Plug in a normal USB-keyboard into any of the KlipperScreen's USB-ports. Rather use a simple keyboard, i.e. not a wireless one and not one that requires special drivers, etc.
  • Have the KlipperScreen powered up
  • Switch to text-mode:
    • At the same time, press the keys “STRG” + “ALT” + “F1” (repeat, if that doesn't work immediately)
    • On success, you will see a lot of text lines (rotated to landscape view).
  • Log in:
    • HINT: The keyboard uses US-keylayout! Keep that in mind esp. if you changed your password. E.g. german keyboards have the “y” and “z” keys switched.
    • Enter the username: mks
    • Enter the password: makerbase
  • The last line is barely visible because of the black frame. Once you are logged in, you can enter clear to clear the screen and put the cursor in the top row, so you can see, what you type.

• Requirements:
  • Terminal software (e.g. putty)
  • KlipperScreen needs working network access (wifi, ethernet)
