You may have your screen installed and tested before kleeperscreen installation
¶ Installation
cd ~/
git clone https://github.com/KlipperScreen/KlipperScreen.git
./KlipperScreen/scripts/KlipperScreen-install.sh
This script will install the necessary packages, create a Python virtual environment at ~/.KlipperScreen-env, and install a systemd service file.
¶ Moonraker Configuration
- Ensure that the IP of the device is a trusted client in
moonraker.conf
[authorization]
trusted_clients:
127.0.0.1
Alternatively, add the Moonraker API key to KlipperScreen.conf
- To use the update manager feature of Moonraker for KlipperScreen, add the following block to
moonraker.conf
[update_manager KlipperScreen]
type: git_repo
path: ~/KlipperScreen

¶ Flash patched U2C firware to make canbus flashing with katapult work for other devices
U2C does not need to be flashed with katapult or klipper to work as canbus bridge
¶ Boot U2C in DFU mode blue led ON
- Disconnect USB cable
- Press BOOT button while connecting usb cable to RPI
- Release BOOT button
¶ Flashing firmware

- Download Flashmagic (bootloader flasher) https://www.flashmagictool.com/download.html
- Power the board via USB or 12V / 24V
- Connect the USB TTL adapter to a Windows PC (potentially you need to install the FTDI VCP Drivers)
- Contact the USB TTL adapter as shown in the picture (cyan arrows)
** RX of the adapter to TX on the board
** TX of the adapter to RX on the board
** GND to GND
- Contact the SMD resistor (R28) to GND of the board (dark blue arrows), e.g. to the middle pin of an endstop (here the female to male jumper cable comes in handy). This will contact the ISP mode pin P2.10
- Reset the board while holding the contact (Nr. 4)
- Shortly after releasing the Reset button also remove the ISP connection (Nr. 4)
- Start Flashmagic
** Chose the katapult.bin file
** Set the correct COM port for your USB to TTL adapter (look it up in the windows device manager)
** Set the correct chip type
** Set Erase to Entire device
** Press start
- Wait until finished, then reset the board

¶ Macros for ease of use
[delayed_gcode DISABLEFILAMENTSENSOR] ; This will disable the SFS 1 second after klipper starts
initial_duration: 1
gcode:
SET_FILAMENT_SENSOR SENSOR=encoder_sensor ENABLE=0 ; Put your filament sensor's name after SENSOR
[gcode_macro SFS_ENABLE] ; Add this to PRINT_START
description: Enable smart filament sensor
gcode:
M117 ENABLING the Smart Filament Sensor

SET_FILAMENT_SENSOR SENSOR=encoder_sensor ENABLE=0 ; Put your filament sensor's name after SENSOR
In this configuration filament sensor is disabled by default.
- Don't forget to enable it at print '''START''', '''RESUME'''
- Don't forget to disable it at print '''END''', '''CANCEL''', '''PAUSE'''
¶ Calibration process
¶ Check accelerometer is working
In klipper interface (where you input gcode)
ACCELEROMETER_QUERY
Must return something like that
Recv: // adxl345 values (x, y, z): 470.719200, 941.438400, 9728.196800
¶ Test X axis resonance
In klipper interface (where you input gcode)
'''!!!! Watch your printer vibrations can be really strong !!!!'''
TEST_RESONANCES AXIS=X
¶ Test Y axis resonance
In klipper interface (where you input gcode)
'''!!!! Watch your printer vibrations can be really strong !!!!'''
TEST_RESONANCES AXIS=Y
¶ Compute input shaper parameters
Previous steps will generate 2 CSV files (/tmp/resonances_x_.csv and /tmp/resonances_y_.csv). These files can be processed with the stand-alone script on a Raspberry Pi. This script is intended to be run with a single CSV file for each axis measured, although it can be used with multiple CSV files if you desire to average the results. Averaging results can be useful, for example, if resonance tests were done at multiple test points. Delete the extra CSV files if you do not desire to average them.
In klipper ssh command line
~/klipper/scripts/calibrate_shaper.py /tmp/resonances_x_*.csv -o /tmp/shaper_calibrate_x.png
~/klipper/scripts/calibrate_shaper.py /tmp/resonances_y_*.csv -o /tmp/shaper_calibrate_y.png
This will output somthing like that
Fitted shaper 'zv' frequency = 116.4 Hz (vibrations = 32.8%, smoothing ~= 0.017)
To avoid too much smoothing with 'zv', suggested max_accel <= 52800 mm/sec^2
Fitted shaper 'mzv' frequency = 73.4 Hz (vibrations = 12.2%, smoothing ~= 0.040)
To avoid too much smoothing with 'mzv', suggested max_accel <= 15900 mm/sec^2
Fitted shaper 'ei' frequency = 100.0 Hz (vibrations = 14.3%, smoothing ~= 0.034)
To avoid too much smoothing with 'ei', suggested max_accel <= 18600 mm/sec^2
Fitted shaper '2hump_ei' frequency = 88.4 Hz (vibrations = 5.7%, smoothing ~= 0.069)
To avoid too much smoothing with '2hump_ei', suggested max_accel <= 8700 mm/sec^2
Fitted shaper '3hump_ei' frequency = 82.2 Hz (vibrations = 0.5%, smoothing ~= 0.121)
To avoid too much smoothing with '3hump_ei', suggested max_accel <= 4900 mm/sec^2
Recommended shaper is 3hump_ei @ 82.2 Hz
Fitted shaper 'zv' frequency = 39.0 Hz (vibrations = 17.9%, smoothing ~= 0.105)
To avoid too much smoothing with 'zv', suggested max_accel <= 5900 mm/sec^2
Fitted shaper 'mzv' frequency = 32.4 Hz (vibrations = 3.0%, smoothing ~= 0.194)
To avoid too much smoothing with 'mzv', suggested max_accel <= 3100 mm/sec^2
Fitted shaper 'ei' frequency = 38.6 Hz (vibrations = 1.4%, smoothing ~= 0.216)
To avoid too much smoothing with 'ei', suggested max_accel <= 2800 mm/sec^2
Fitted shaper '2hump_ei' frequency = 42.8 Hz (vibrations = 0.0%, smoothing ~= 0.295)
To avoid too much smoothing with '2hump_ei', suggested max_accel <= 1900 mm/sec^2
Fitted shaper '3hump_ei' frequency = 52.4 Hz (vibrations = 0.0%, smoothing ~= 0.298)
To avoid too much smoothing with '3hump_ei', suggested max_accel <= 1900 mm/sec^2
Recommended shaper is ei @ 38.6 Hz
The only 2 lines that will be needed are
# For x axis
Recommended shaper is 3hump_ei @ 82.2 Hz
# For y axis
Recommended shaper is ei @ 38.6 Hz
Now you can append your parameters in printer config file
[input_shaper]
shaper_freq_x: 82.2
shaper_type_x: 3hump_ei
shaper_freq_y: 38.6
shaper_type_y: ei
You can also adjust your max_accel with the minimum values suggested by the shaper choices
¶ Z axis Calibration
-
Home axis with '''G28'''
-
Change '''position_min: 0''' to '''position_min: -5''' in '''printer.cfg''' for '''stepper_z'''
-
Go to middle plate with macro '''probe middle plate'''
-
In console type '''PROBE_CALIBRATE'''
-
Get a paper and move your extruder close to the paper with instructions: '''TESTZ Z=-.1''' '''TESTZ Z=+.1''' '''TESTZ Z=+1''' '''TESTZ Z=-1''' or using the buttons
-
When good, type '''ACCEPT'''
-
Don't forget to save with '''SAVE_CONFIG'''
-
Change '''position_min: -5''' to '''position_min: 0''' in '''printer.cfg''' for '''stepper_z'''
-
