    bootloader

    I was following the instructions to update the bootloader after I was given the link (and saw that no version was listed).

    M997 B10 S3

    Board 10 starting bootloader update

    I never receive a complete message.

    After about a minute, I checked m122 again.

    Bootloader ID: SAMC21 bootloader version 2.2 (2021-01-16b1)
    

    BLTouch is still not working... Even after rebooting...
    Red LED blinking fast/dim, and Self Test does not do anything.

      if the red LED in BLTOUCH flashes at 80% duty right after the 3D printer is switched on, please release it with S60 or S160.

        I am not sure what you mean by 80% duty... The LED is just blinking fast and is very dim. Does this mean the LED is at 80% power? If so, then no, it is much dimmer than that, more like 50% power (as that is another option in the manuel).

            I ran these...

            M280 P9 S60
            M280 P9 S160
            M280 P9 S10
            M280 P9 S90
            M280 P4 S160
            M280 P4 S60
            M280 P4 S120
            M280 P4 S10
            M280 P4 S90

            BLTouch is only blinking the RED LED fast at low power.

                    Thought now is that in/out pins are reversed?

                      is the blackwire not ground?

                      that is connected to io.out

                        Yes... that is what it looks like I did. After I uploaded the pictures, I was looking at my notes and fixed it.
                        See what happens momentary... That's what I get for wiring the BLTouch by feel, as I didn't have good visibility, was awkward when I wired it.

                          unrelated but don't do that

                          cut the crimped thingies out and stick the wire directly in the connector. Those are just for high currents.

                            @matt3o Crimps are not always for high currents. Bare multistranded wire likes to not go in cleanly.

                              Except for M280 P0 S160 doesn't reset/pull the pin up.

                                @Stephen6309 okay, let's just say that those connectors are not made for crimps

                                  Once I have this all permanently wired, I planned to cut them down to size so they fit in cleanly. Will have to squeeze the white barrel to flatten it a bit... And yes, they are all stranded wires. Would prefer to keep them neat, and not worry about a runaway wire touching another terminal.

                                    @BlueDust you can always put some solder on the tips (ONLY on low currents like those)

                                      There is obviously not a lot of room between the screw terminals to fit them properly.

                                        That is an idea... Thanks. Will consider it when it comes time to re-wire and make this a permanent setup.

                                          I'd say that's not a good idea. The solder tin doesn't compress at all like the wire strands would, so you might be get very good pressure. Back to same problem as using the bootlace ferrules.

                                          Give the bare wires a twist with your fingers to keep them tidy and then screw them down.
