        Even without the CAN cable, with VIN power applied to the tool board you should get 2 LEDs lit and another one flashing. Please post photos showing how 24V power is supplied to VIN on the tool board.

            @dc42 I supplied the Vin direct from my 24v power supply to the Vin of the tool distribution board. And from there with the first port to the toolboard lc1. I need 2 more hours at my office. I will send you the pictures as soon as I am at home. Could I test some other parts with my multimeter to check the correct function?

              I checked the connections and fuses with the multimeter. Everything ok. 24.1v on the toolboard. But no led are on.!IMG_20201209_191716.jpg

                  @dc42 Thank you, Problem Solved.
                  I rewired the distro and toolboard + making new crimps for my vin cables.

                  i was measuring the 24v on the bottom of the connector and checked the polarity.
                  But somehow the connection made no contact to the toolboard.when plugged in
                  I also updated my duet3 to RRF 3.2beta4.1

                  now the blue led is on and the red led is constantly on like the diag led on the duet 3, but not flashing. Is the firmware wrong?
                  What is the next thing to check?
                  Pressing the 2 buttons while starting the board doesn't change the led signals.

                  Is there another way to reset the toolboard and check the CAN connection?
                  Regards

                    it might not matter, but the tool distribution board you showed is missing a bypass jumper on the 4th unused output and doesn't show the jumper for the 1st you're actually using.

                      @bearer thanks for pointing that out. I uploaded the wrong photo. The jumpers are both removed from the first port with the cable and are set in every else slot.IMG_20201210_061343.jpg

                      I test both ways. With only one of the two jumpers removed and both jumpers removed. The same result in the console and no change in led behavior.

                          M997 B121 S3
                          Error: M997: Response timeout: CAN addr 121, req type 6024, RID=14
                          

                          everything I try only generates this timeouts. M115, M122, M997... Are there other parts to test with the multimeter to ensure that I got a working unit?

                            this would indicate that there is something wrong with your can wiring.

                              @Veti I use a straight through 4 pin can cable that I made with the lc1 connector pack

                                have you done the simple setup and tested that?

                                https://d17kynu4zpq5hy.cloudfront.net/igi/duet3d/IgXsNbOKcEAWjeNO.huge

                                also check the continuity of your can wiring. a bad crimp here will also be a headache.

                                  @Veti I would try if I'd had a 120ohm resistor and a spare rj11 cable at Hand. I can source a bunch of those resistors later at my local electro shop.

                                      for the entire chain? with the distribution board?

                                        Could a short to the stepper motor metal case cause the board to behave like that?

                                            please check the entire chain.

                                            pull out the plug on the duet 3 and the 1lc and check the resistance for the L and H can cable with the toolboard beeing in place
