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 done.

• 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

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