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.

• 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

• Printers with z_tilt or quad_gantry_level (QGL) functionality should perform multi-z leveling.

Tips:

• Set your xy offset according to the following images, and proceed to the next step xy offset calibration (Probe_Calibrate) method

Step 1 Calibration 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 coordinates Calculation method: divide the maximum value of the heated bed by 2, adjust it yourself
speed:300                    # Homing speed
z_hop:10                     # Height to lift before homing

• Click the macro command CALIBRATE_DD shown in the picture and execute it

• Control the z-axis tool head to touch the heated bed through the console, then continue operating according to the instructions

• Click the macro command CALIBRATE_EDDY shown in the picture and execute it

• Click the macro command CALIBRATE_EDDY shown in the picture and execute it

• Then the following UI interface will appear (if it does not appear, refresh the page)
• Adjust the Z—offset with A4 paper on the UI interface that pops up. Before adjusting the z—offset value, please refer to the Klipper documentation tutorial Paper test
• Find the appropriate value and click ACCEPT

• After completing the calibration, SAVE_CONFIG to save the parameters

info

• Completed the test homing
• If there is no normal homing
• Find the following file to modify the reference current value. For example, if it is 20, then +1 to test, if not, -1 to test. If it still does not work, recalibrate
• If modifying the current value still does not work, modify the z-offset value, which is default 1.0, change it to 2.0

Step 2: Temperature compensation

info

• Do not heat the heated bed, nozzle before doing temperature compensation

• Execute the macro command TEMP_COMPENSATION shown in the following picture and click to execute

1. After executing this operation, the UI will display a Z-axis adjustment box. Please use the manual Z-axis offset calibration (Paper Test) method mentioned above, clamp the paper between the nozzle and the bed, and then confirm the value.

2. 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.
3. If you are in a room with air conditioning or open windows, it is recommended to turn off the air conditioning or close the windows to ensure that Eddy's temperature rises, as wind can affect the temperature rise.
4. As Eddy's temperature increases, the system will automatically prompt you to perform a manual Z offset calibration every 3°C. The heated bed is very hot, be careful not to get burned!!!

5. Repeat the manual Z offset calibration (Paper Test) until the calibration is complete. If you find that Eddy's temperature no longer rises, you can use the following commands to end the calibration early.

• Additional gcode commands available during drift calibration include: TEMPERATURE_PROBE_NEXT
• TEMPERATURE_PROBE_NEXT is used to force EDDy to sample new data before reaching the target temperature 80℃ set for EDDy.
• TEMPERATURE_PROBE_COMPLETE is used to complete the calibration before EDDy reaches the set temperature 80℃.
• ABORT can be used to terminate the calibration and ignore the results.
• When the 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 achieve excellent first-layer printing results over a wide temperature range!

How to fine-tune z—offset

• Step 1: Use pursa/OrcaSlicer/cura/Bambu Studio to print a 200x200 height 0.2 square to fine-tune the z—offset
• Step 2: Enter fluidd or mainsail via the printer's IP address and find the dashboard Move control to adjust the z axis offset z_OFFset

• After completing the calibration, SAVE_CONFIG to save the parameters

The value has not changed

• Find the corresponding file in the picture and modify it inside

• After completing the calibration, SAVE_CONFIG to save the parameters

info

• After completing the above operations, if the bed scanning fails, change the z limit to virtual limit, and cover the original endstop_pin endstop_pin: probe:z_virtual_endstop
• If you have modified the z_offset value, you need to modify the horizontal_move_z=2 value in the eddypz.cfg file. Change 2 to the z_offset value you are currently using
