hi, I have a very rare compatibility problem
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???
klippy log were!
