Eddy Usage

info
  • If you have previously configured the eddy settings, please delete them.
  • When installing Eddy, the coil should be above the nozzle and 0.6-0.8cm away from the nozzle.
  • Do not turn on the heated bed during testing.
  • Before use, delete the probe configuration in the settings.
Notice
  • For multi-Z axis machines, manual leveling needs to be done once properly.

Wiring Diagram​

  • Install the trademark facing the heated bed.

Usage Instructions​

  • Log in to the terminal via SSH tool using the IP address, and execute the script. Download the required SSH tool MobaXTerm tool

Please use the following command for international users.

Below is the start of the installation of the eddy automated script.​

  • Open the downloaded SSH tool, enter the following command and press Enter, then click copy.
rm -rf ./Eddy-Automated-Configuration-Script
git clone https://github.com/xishangyue/Eddy-Automated-Configuration-Script.git
sudo chmod +x ./Eddy-Automated-Configuration-Script/eddy1.sh
./Eddy-Automated-Configuration-Script/eddy1.sh
  • In the fluidd web page's moonraker.conf configuration file, add the following configuration for easier updates later.
[update_manager Eddy-Automated-Configuration-Script]
type: git_repo
channel: dev
path: ~/Eddy-Automated-Configuration-Script
origin: https://github.com/xishangyue/Eddy-Automated-Configuration-Script.git
primary_branch: main
install_script: eddy1.sh
managed_services: klipper
  • If you have updated, use the SSH tool to execute the following commands.
sudo chmod +x ./Eddy-Automated-Configuration-Script/eddy1.sh
./Eddy-Automated-Configuration-Script/eddy1.sh
  • Execute it and if shown as in the figure, input your host machine password.
  • If shown as in the figure, input the corresponding number for your printer, there are Chinese and English options, press Enter after inputting.
  • Choose 3z to ensure that the printer.cfg has the z_tilt configuration or choose 4z to ensure that the printer.cfg has the quad_gantry_level configuration. For independent dual Z-axis, select 3z. Configuration reference
  • If shown as in the figure, you need to input Y and press Enter.
  • If you are using sht36_v3, input N and press Enter.
  • If shown as in the figure, it means success.
info
  • For printers with z_tilt or quad_gantry_level (QGL) features, remember to perform multi-Z leveling.

Tips:​

Step 1: Calibrate EDDY​

info

Divided into two small steps.

  • Step 1
  • Check if your homing macro is safe_z_home. If configured, proceed to the next step.
[safe_z_home]                
home_xy_position:150,150     # XY center point coordinates, calculated by dividing the maximum bed size by 2 and adjust accordingly
speed:300                    # Homing speed
z_hop:10                     # Lift height before homing

  • Click the macro command CALIBRATE_DD shown in the image and execute it.

  • Use the console to move the Z-axis toolhead to touch the heated bed, then continue with the prompts.

  • Click the macro command CALIBRATE_EDDY shown in the image and execute it.

  • Click the macro command CALIBRATE_EDDY shown in the image and execute it.
  • Then the following UI interface will appear.
  • Adjust the Z-offset value using an A4 paper in the popped-up UI interface. Before adjusting, refer to the Klipper documentation tutorial Paper Test.
  • Once the appropriate value is found, click ACCEPT.
  • After calibration, save the parameters with SAVE_CONFIG.
info
  • The test homing is complete.
  • If it does not return home normally,
  • Modify the reference current value by referring to the files below.

Step 2: Temperature Compensation​

info
  • Do not heat the heated bed or nozzle before performing temperature compensation.
  • Execute the macro command TEMP_COMPENSATION shown in the image and click to run.
  1. After executing this operation, the UI will display a Z-axis adjustment box. Use the manual Z-axis Offset Calibration (Paper Test) method mentioned above, insert a piece of paper between the nozzle and the bed, and confirm the value.
  1. After accepting the value, the heated bed temperature will automatically be set to 80°C, and the nozzle temperature will be set to 250°C.
  2. If you are in a room with air conditioning or open windows, to ensure the temperature rise of Eddy, it is recommended to turn off the air conditioning or windows as wind may affect the temperature increase.
  3. As the Eddy temperature rises, the system will automatically prompt you to manually calibrate the Z-offset every 3°C. Be cautious of burns as the heated bed temperature is very high!
  1. Repeat the manual Z-offset calibration (Paper Test) until calibration is complete. If you find that the Eddy temperature no longer rises, you can use the following relevant commands to end calibration early.
  • During drift calibration, additional available G-code commands include: TEMPERATURE_PROBE_NEXT
  • TEMPERATURE_PROBE_NEXT - Used to force Eddy to sample new data before reaching the target temperature of 80°C for EDDy.
  • TEMPERATURE_PROBE_COMPLETE - Used to complete calibration before Eddy reaches the set temperature of 80°C.
  • ABORT - Can be used to terminate calibration and ignore the results.
  • When calibration is complete, use SAVE_CONFIG to save the temperature offset settings!
  • In summary, compared to most other programs, the above calibration process is more challenging and time-consuming. It may require practice and multiple attempts to provide excellent first-layer printing results over a wide range of temperatures!

How to Fine-Tune Z-Offset​

  • Step 1: Use pursa/OrcaSlicer/cura/Bambu Studio to slice a 200x200mm square with a height of 0.2mm to print and fine-tune the z-offset.
  • Step 2: Access fluidd or mainsail via the printer's IP address to find the dashboard Movement Control, where you can fine-tune the Z-axis offset z_OFFSET.
  • After calibration, save the parameters with SAVE_CONFIG.

No Changes in Values​

  • Find the corresponding file in the image and modify it inside.
  • After calibration, save the parameters with SAVE_CONFIG.
info
  • After completing the above operations, if the sweeping bed fails, please change the Z limit to a virtual limit and overwrite the original endstop_pin endstop_pin: probe:z_virtual_endstop.
