How do i access mini5+ as as expansion board

[Behrouz-AKT]

I am using two mini5+ board connected via can bus - I have one set as the main and the other should be set as an expansion board but I dont think its working. the two boards are identical Mini5+ WIFI version 1.02 . I am using SW version 3.46 on both boards

Also I have uploaded Duet3_CANiap32_Mini5plus.bin on the expansion board only as shown below.

How do I confirm that the second board has loaded as an expansion board ?

Also I am assuming the expansion board is referenced as 1st expansion board and driver0 on the expansion board is "1.0"

Any help or guidance is much appreciated

@Behrouz-AKT on the Mini 5+ as expansion board, the SD card needs a config.g file with a M954 command in it. Then you should be able to send M122 B[Mini 5+ as expansion CAN address] to check it is working. See https://docs.duet3d.com/User_manual/Machine_configuration/CAN_connection#mainboard-used-as-expansion-board
