EDDY Frequently Asked Questions

Note

Prompt: `Error during homing z: Eddy current sensor error`

Method 1:

For this error, go to the bottom of the printer.cfg configuration file and find reg_drive_current =. Adjust the value the arrow points to by either adding +1 or subtracting -1, then save and restart, followed by testing.
Tip: +1 or -1 does not mean you should directly type it in; instead, calculate the new value and replace the existing one. For example, if the original value is 15, enter 16 or 14 after calculation, not expressions like 15+1 or 15 -1.

Method 2:

If the issue persists, you need to increase the z_offset: value in the [probe_eddy_current fly_eddy_probe] section. Change the default value of 1.0 to 2.0 or 2.5, save, restart, then test.
Tip: Do not repeatedly configure the z_offset: value in [probe_eddy_current fly_eddy_probe], and do not exceed 3.
Note: The actual adjustment of z_offset: depends on your machine design. This is only a reference.

Method 3:

You can add a # before i2c_speed: 400000 in [probe_eddy_current fly_eddy_probe] to comment it out, save and restart, then test.
Tip: After commenting out and restarting, it is recommended to recalibrate.
If the homing works normally but the z_offset is greater than 2.0, you need to adjust the parameters in the eddypz.cfg file.

Due to certain reasons, EDYY does not process scan height settings in other sections such as [Horizontal_move_Z] or [bed_mesh].
