      Hi all,

      I'm setting up a Duet 3 Mainboard 6HC and trying to drive a closed-loop stepper motor through a 1HCL expansion board. However, I can't seem to get the CAN connection to work at all.

      The only LEDs that light up on the 1HCL are V_FUSED and +12V, while STATUS remains completely off. The RJ11 cable is straight through.

      I've attempted to reset the CAN address back to the default by shorting the CAN_RST pins, but that appears to have done nothing. I get this message typing in M122

      M122 B123
      Error: M122: Response timeout: CAN addr 123, req type 6024, RID=7
      

      This is my config.g file

        firmware version on the 6HC?

        Can you send M122 and M98 P"config.g" and share the results?

            @big_plotter_man please disconnect everything from the 1HCL except power and CAN, and see if the status LED then flashes when you power it up.

              @dc42 the STATUS LED on the 1HCL doesn't flash with only power and CAN connected either.

                @big_plotter_man thanks.

                @Phaedrux please arrange a warranty replacement.

                    @dc42 Apologies about the delay.

                    I received the 1HCL warranty replacement and installed it as before, but the connection problem persists; the MB6HC still doesn't recognize the expansion board, the STATUS LED on the 1HCL doesn't flash (the V_FUSED LED does light up solidly and the voltage indicators flash rapidly)

                    I attempted to diagnose the issue by seeing if there were any obvious problems such as powering the Mainboard and 1HCL with separate power supplies, checking the continuity of the RJ11 cable and voltage (there is continuity and voltage), cutting open the the RJ11 cable to see if their wires were twisted (they weren't), reflashing the Mainboard's firmware.

                    Nothing has worked and now I'm stumped.
