Eddy Usage

info

• Ensure your printer is not leaking electricity before use
• If there was a previous configuration for eddy, please delete it
• When installing Eddy, the coil should be above the nozzle and 0.6-0.8cm away from the nozzle
• Do not open the heated bed during testing
• Delete the probe configuration in the configuration before use

Notes

• Machines with multiple Z-axes need to be manually leveled once

Wiring Diagram

• Install with the brand facing the heated bed

• If the display shows as below, enter your host computer password

• If the display shows as below, select input and enter the corresponding number of your printer, choose between Chinese and English, then press Enter
• Select 3z to ensure printer.cfg has the z_tilt configuration or select 4z to ensure printer.cfg has the quad_gantry_level configuration, select 3z for independent dual Z Configuration reference

• If the image shows, you need to enter Y and press Enter

• If you are using sb2040-v3-PROV3, enter y and press Enter

• If the display shows as below, it is successful

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

First calibration of EDDY

info

Divided into two small steps

• First step
• Check if your homing macro is safe_z_home. If it is 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 using A4 paper on the UI interface that pops up. Before adjusting the z—offset value, check 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 current value. For example, if it is 20, then try +1, if not, try -1. If it still doesn't work, recalibrate
• If modifying the current value still doesn't work, modify the z-offset value, which is default 1.0, change it to 2.0

Second step: Temperature compensation

info

• Do not heat the bed or nozzle before performing 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, insert a piece of paper between the nozzle and the bed, and confirm the value.

2. After accepting the value, the bed temperature will automatically be adjusted to 80°C, and the nozzle temperature 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 temperature rise.
4. As Eddy's temperature rises, the system will automatically prompt you to perform a manual Z offset calibration every 3°C. The bed temperature is very high, be careful to avoid burns!!!

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 set target temperature of 80℃.
• TEMPERATURE_PROBE_COMPLETE is used to complete the calibration before EDDy reaches the set temperature of 80℃.
• ABORT can be used to terminate the calibration and ignore the results.
• When the calibration is completed, 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 effects over a wide temperature range!

How to fine-tune z—offset

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

• After calibration, SAVE_CONFIG to save the parameters

The value has not changed

• Find the corresponding file in the picture and modify it

• After 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, override 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 current z_offset value you have
