Eddy Coil vs Knomi v2 big problem #67

I doubt that it has much to do with the magnetic or electrical field. It is more likely that the 5V power supply is struggling to keep up with the Eddy Coil and the KNOMI at the same time. When you say that you are turning off the power of the Eddy do you mean that you are unplugging it? |
5v power supply. This is the first thing I checked! Everything is fine with
it! KNOMI consumes an average of 5v. 0.2A
I pulled out the knomi and connected it via USB from a laptop, and brought
it closer to the eddy, the Wi-Fi signal was immediately lost! And one more
piece of news! Today I reflashed the firmware on all the boards and it got
better! But the signal is still lost!

… hi, I have a very rare compatibility problem! Most likely, no one will
help me solve it, but I will write this! My equipment: Voron 2.4 board
Manta-M8P v2 + CB1, head Stealthburner with EBB 2240, Eddy Coil , Knomi v2
Eddy coil is connected to the i2c port on the MP8 v2 board Knomi v2 is
connected as usual via wi-fi Eddy coil is configured, works fine, scans and
levels the table! """The essence of the problem: i turn on the 3d printer,
while the Klipper is loading, the Knomi v2 loses wi-fi, as soon as i turn
off the power of the Eddy coil, the Knomi v2 starts working as it
should!""" I have already tried everything! I changed the Knomi v2 wifi
antenna, connected separate 5v. tried different firmware Knomi v2. I did a
bunch of experiments! As soon as the Knomi v2 is inside the 3D printer, the
Wi-Fi connection is immediately lost! I suspect that the problem is in the
large magnetic field!!! it is also interesting that the CB1 board has no
problems with wi-fi! the CB1 board is under the table, maybe that's why!
"""Sometimes an error appears MCU shutdown: i2c timeout !!!""" Gentlemen,
do you have any thoughts???
