Knomi v2 vs Eddy Coil conflict

I checked the datasheet, and ldc1612 can be returned to sleep mode.

question about Klipper! tell me please
is there a code in the ldc1612 library to go into sleep mode when turned on?
at the end of the measurements I see that there is! I’m interested in the beginning
when the printer is turned on, there is a command to sleep on Eddy

[nefelim4ag]

I strongly suggest you read the datasheet to ldc1612, which as far as I am aware used in eddy before you implement the external switch.

there is a command to sleep on Eddy

I strongly suggest reading the datasheet. I stated above, that it should be in sleep mode until the first command arrives.

Nonetheless, you are free to place sleep command where you want.

you are a very interesting person!) you communicate with me as if I were an expert in reading codes!
I have already said many times that I do not understand the code as well as you!
if you directly indicated which section of code and where exactly to add then I would try!
even if we add Eddie’s code at startup, will the controller immediately send it when the power is turned on or will it wait for Klipper to load???

[borysne]

So let’s start checking
according to the datasheet Ldc1612
Power consumption:
– 35 μA Low Power Sleep Mode
– 200 nA Shutdown Mode
we’ll check the current consumption and we can roughly understand what mode Eddie is in when turned on

the difference between active mode mode is 3mA)))
my multimeter probably won’t measure this)
let’s try)

[borysne]

these are the current values ​​shown during the operation of the table scanning sensor.
otherwise the consumption is almost 0.02mA
so the sensor is in sleep mode!
@nefelim4ag’s idea to write additional sleep in the code will not give any result!
so the only way to make it all work is to turn off the 5v power supply to Eddy when it is not working!!!

[borysne]

and finally!
connected the Eddy power supply to the FAN1 fan connector on the SB2240 board. connected the hotend blower fan to the 4WFan connector. i ordered a 4pin fan then I’ll replace it!
reassign pins in the configuration, do not forget to select voltage jumpers!!! Eddy 5v. 4WFAN - voltage of your fan
In this configuration, everything works fine.

create your own macros associated with Eddy and add the Eddy pin enable at the beginning and at the end! for example

[output_pin Eddy_power]
pin: "Your pin"

[gcode_macro RAPID_SCAN]
gcode:
   SET_PIN PIN=Eddy_power VALUE=1       ###  Eddy power ON
   {% if "xyz" not in printer.toolhead.homed_axes %}
   G28
 {% endif %}
  G90 # Abs positioning
  G1 X{ printer.toolhead.axis_maximum.x/2 } Y{ printer.toolhead.axis_maximum.y/2 } F6000
  BED_MESH_CALIBRATE METHOD=scan SCAN_MODE=rapid
  SET_PIN PIN=Eddy_power VALUE=0        ###  Eddy power OFF

[borysne]

A bit inconvenient! you can’t start it with this button!
No access to this macro! It would be ideal to add to the Probe library so that everything related to Table Measurements and Probe would initially include the Eddie pin! Then you don’t need your own macros! But my knowledge is not enough yet and there is no one to tell me! Later I will figure out how to edit inside the Klipper library and share with you!
