      I am slowly continuing to work on converting my printer to tool board. Today I connected my duet IR probe and was surprised by the fact that it's not supported:

      Error: M558: M558: only Z probe types 8 and 9 are supported on expansion boards

      Is adding Z probe type 1 on the list for supported probes on tool boards in the new future? Or should I run it in mode 8?

        Hmm. This seems to have slipped by. Anyone?

          You should run the IR probe in mode 8. All Duet 3 boarts have permanent pullup resistors, so the IR probe will start up in digital mode (2 flashes).

            Thanks for the info! I tried mode 8 and the probe does not turn on (DWC says probe is not available). I'll see if I find another problem with my setup.

              @oliof said in Supported Z probe types on expansion boards / tool boards:

              probe does not turn on

              What do you mean by that? Does the LED flash twice?

                PS - also, which firmware version are you running on the expansion or tool board and the main board? You need 3.01-RC3 or later on both.

                    @dc42 the probe does not flash on turnup and there is nothing reported in the firmware. Everything else on the toolboard works.

                      OK, I found the problem: I was using IO1, which is only providing 3V, which does not seem enough to turn on the probe. Switching to IO0 with 5V solved the issue.

                        And now I have a new problem: Probe runs and probing for Z works, but after that the probe is stuck at 1000 in DWC and I can't do auto leveling with the multiple independent axes.

                          IO1 should work, however IO0 is intended for the Z probe.

                          I think the "stuck at 1000" is a firmware issue, I only tested with a bltouch, and I can see why that might behave differently. I will look into it.

                            PS - possible workaround for now: repeat the M558 command in the deployprobe.g file

                              The workaround helps! I wasn't able to get my independent z axis leveling script to run, but running the commands individually worked.

                              Thanks for your help!

                                There is a new firmware build at https://www.dropbox.com/sh/3azy1njy3ayjsbp/AACquxr2m00eV568RZg5QG5wa?dl=0 which fixes the original problem. I have tested it using an IR sensor with both the IO0 and IO1 connectors. The fix is in the main board firmware. However, if you don't already have the new tool board firmware installed, you will need it when you come to use the tool board stepper motor.

                                  I am currently not using the tool board stepper motor. Will give this a run and report back (-:

                                    With the new firmware, G28 Z is stuck in an infinite repeat loop. Only M999stops this, with the unfortunate drawback that the machine isn't homed anymore after an emergency restart (I triedM0andM1` and they do not get executed).

                                    Here's my homez.g

                                    ; homez.g

                                    G90                  ; absolute positioning

                                    ; Uncomment the following lines to lift Z after probing

                                      Are you running in standalone mode or with attached SBC?

                                      Does G30 sent from the console work OK?

                                        I am running attached to an SBC. Just a G30 also loops.

                                          G30 via pronterface does not loop. G30 via DWC loops.
