Duet 3 6HC and 3HC
-
I have my duet 3 6HC setup and connected via my Pi 4. I added my 3HC with CAN bus and power. How do I check that both boards are seen?

@rmilyard See https://docs.duet3d.com/Duet3D_hardware/Duet_3_family/Duet_3_Mainboard_3HC_Hardware_Overview#can to set the CAN address and check the hardware connection.
The DIAG LED between the two CAN connectors indicates CAN bus state. When the expansion board starts up this LED will blink rapidly. If the expansion board is connected to a main board running compatible firmware, the LED on the expansion board will switch to blinking synchronously with the main board LED once time sync has been established across the CAN bus.
To check they are talking, and that both 6HC and 3HC are on the same firmware version, see https://docs.duet3d.com/Duet3D_hardware/Duet_3_family/Duet_3_Mainboard_3HC_Hardware_Overview#commissioning
