MCU 'EBBCan' shutdown: Invalid oid type - Seems linked to realtime level

[feral42]

This happens when I try to enable realtime leveling.
I follow the instructions to enable and test:

G28
BDSENSOR_SET REAL_TIME_HEIGHT=0.3
G1 Z0.3

as soon as the nozzle gets to the 0.3 mark it crashes with:

Klipper reports: SHUTDOWN

MCU 'EBBCan' shutdown: Invalid oid type
Once the underlying issue is corrected, use the
"FIRMWARE_RESTART" command to reset the firmware, reload the
config, and restart the host software.
Printer is shutdown

and I get this in the console:

2:21 AM
Klipper state: Shutdown

I have a Manta M8p V2.0 with CB2 installed on it. It has a SB2240 attached using usb, and that is what the BDSensor is hooked to.

I've attached my relevant configs and logs.

Thanks for any insight you can provide!

the reason is that the realtime level only support the BDsensor and z motors are connected in the same MCU.
here needs to connect the bdsensor to the M8p board.
