      Hi

      I face error on connection of Duet 1XD with MB6HC:
      Error description:
      a) Error M115: Response timeout: CAN address 122 request type 6024 RID0
      b) the LED blinks more frequently than mainboard.

      I have followed the guidelines to connect Duet 3 1XD with the mainboard. Also included line to wait for exp. board to power up on start. Tried the step to include jumper-> poweron-<power off-> remove jumper-> power on. Tried CAN termination as I am using only one 1XD board. Tried swapping CAN channels too. Nothing worked.

      @T3P3Tony @dc42 @Phaedrux can you suggest any other things to try ?

        please post your config.g and the results of M122 and M98 P"config.g". Also send a M122 B1 or M122 B2 etc for each additional expansion board you have.

          That sounds like no CAN communication. What cable have you used to connect the 1XD to the MB6HC?

            @dc42 : RJ11 conector, 4 wire, same as dsl lines (as suggested). It's not working.

            To connect in daisy chain method, it has to be 1-1 connection or cross wired ?

              @JayT : Problem resolved, we just swapped the internal cables (to make sure it's 1-1 connection). i.e. CANH to CANH. The LED blinked right on power up in sync with MB6HC. This thread can be closed. thanks.
