      I am missing some basic information for understand how all the macro interact I reach this results simply copying some posted configuration but I don't understand how the firmware works
      When I launch a print, how can I practically run a bed leveling routine and bed compensation?

      I understand from the wiki there are 2 bed leveling system
      G29 and G32 ( G29 is better for a core xy) so I went for G29 .
      I have to use M557 command but where? I made a macro with this inside
      [c]G91
      G1 Z6 F200
      G90
      M98 Pdeployprobe.g
      G29 S2
      M557 X30:270 Y30:270 S60
      G29
      M98 Pretractprobe.g[/c]
      and I can run it with G29 so I understand I could simply put G28 and then G29 in the start script in the slicer program , is that right?

      What if I would use a simply 5 points bed leveling using something like this
      [c]G30 P0 X50 Y50 Z-99999
      G30 P1 X50 Y250 Z-99999
      G30 P2 X250 Y250 Z-99999
      G30 P3 X250 Y50 Z-99999
      G30 P4 X150 Y150 Z-99999 S0
      [/c]
      where I should place this commands and How I should run it?

      Hope You'll excuse me for such dumb questions but I always used Marlin based printer till now 😞
      Thank you very much

        Have you read https://duet3d.com/wiki/Using_mesh_bed_compensation ?

        You can put the M557 command in config.g assuming that you always want to probe the same bed area. Or it can go in the same file as the G29 command.

        Your mesh bed levelling macro looks ok but the G29 S2 line is not needed because the height map is automatically cleared at the start of the other G29 command.

        Your 5 point probing sequence also looks good, but of course you need to deploy the probe at the start and retract it at the end.

        You could put either sequence in your bed.g file so that you can invoke it with G32.

          Thank you for all your patience and assistance.

          Yes I read that part about 30 times 🙂 Maybe I am missing some basic concept.
          This is the part I can't understand

          You can put the M557 command in config.g assuming that you always want to probe the same bed area. Or it can go in the same file as the G29 command.
          You could put either sequence in your bed.g file so that you can invoke it with G32

          • If I understand correctly G29–> mesh bed levelling G32-->Probing at fixed points But I am missing the practical differences between this 2 commands.
            if I'd put all the 2 sequences in bed.g with G29 command will be executed the mesh levelling instead with G32 will be executed the 5 points leveling is that correct?
            -When I run a G29 command what config files are read by the board? And when I run a G32? Always look in bed.g if present?
          • How bed.g Config.g and a Macro interact?
          • You said that putting the M557 command in config.h will be tested always the same area, Do you mean that having differents macros for bed levelling I can starts it in many ways following may needs? How can I test 2 different pattern mesh map using G29 command? How can coexist 2 M557 command ? Using 2 differents macros?

          I have another problem , when I home the Z probe seems to work perfectly, the printer register the touch point and the home Z button become blue . The problem is the probe that after touching the bed with the pin it start flashing and I have to reset it manually https://www.youtube.com/watch?v=eq2wTy3-kxA
          this is my homing routine

          [c]G91 ; relative mode
          G1 Z4 F200 ; raise head 4mm to ensure it is above the Z probe trigger height
          G90 ; back to absolute mode
          M98 Pdeployprobe.g
          G1 X150 Y150 F2000 ; put head over the centre of the bed, or wherever you want to probe
          G30 ; lower head, stop when probe triggered and set Z to trigger height[/c]

          Hope you'll be able to understand my very mad English 🙂

            There are two sorts of bed compensation you can do:

            1. Mesh levelling, using M557 to define the grid and G29 S0 (or just G29) to probe it. The height map is saved to a file, the default filename is heightmap.csv. You can also load a previously-generated height map using G29 S1.

            2. Bed probing using a sequence of G30 commands. On Delta printers this does auto calibration. On Cartesian printers it is an older way of doing bed compensation, provided for backwards compatibility with older firmware that didn't support mesh levelling.

            The G32 command simply runs the bed.g file.

            On a Cartesian printer, you can use either mesh levelling (G29) or G30 probing, not both. I recommend mesh levelling. So I suggest you put your mesh levelling script in bed.g.

            I'll leave it for someone who has a BLTouch to help you with your BLTouch issue.

                  Hi everyone.

                  I've read through this entire thread 3 or 4 times now and I still can't get my DuetWiFi-BLTouch deploying, let alone retracting or bed levelling.

                  I've followed the BLTouch Wiki through and have the exact wiring connections.

                  What happens when I run a Home All, or even a Deploy Command, M401 or M280 P3 S10 I1, it homes X and Y successfully, then throws this error: INVALID M CODE: M401, or INVALID M CODE M280 P3 S10 I1, if I have changed all the deploy commands to the latter. I haven't been able to find this error code anywhere on the Duet forum or the internet.

                  When I start the Tevo Black Widow printer, the BLTouch lights up and deploys and retracts twice, before defaulting to the constantly lit state with the pin up. I had been using it perfectly fine with the MKS board, before switching to the Duet. I also don't have any macros set up yet, so I don't know if that's an issue for testing the BLTouch or running a home command.

                  I've been working on it for 4 days straight now and I have no idea what to do, please help.

                  Here's my config.g, which was set up by someone in my FB group:

                    What version of RepRapFirmware are you running? It must be quite old if it doesn't support M280 or M401.

                      I don't have access to my BW config file at work here, but one thing I would try, is to leave off the I1 (invert polarity) in the M280 command. When I used the BLTouch, it would not work with that parameter set.

                      So basically just try this to deploy:
                      M280 P3 S10

                            You will need the I1 parameter on the M280 command if you have the BLTouch connected to the Heater 3 pin on the expansion connector. If you have a DueX2 or DueX5 connected and you connect the BLTouch to one of the servo outputs on the DueX instead, then you don't need the I1 parameter.

                              If there was a wiring diagram to show that the connections for the BLTouch was to the 4pin Z-probe input, and not the 3pin Z-endstop input, this would have been helpful 2 days ago. To the laymen and on other control boards, there is no differentiation between these items. It would not be conceivable to have an z endstop and a z probe existing at the same time.

                                You will need the I1 parameter on the M280 command if you have the BLTouch connected to the Heater 3 pin on the expansion connector. If you have a DueX2 or DueX5 connected and you connect the BLTouch to one of the servo outputs on the DueX instead, then you don't need the I1 parameter.

                                It's just the Duet WiFi by itself. I have tried the M280 command with the I1 parameter, and it doesn't work. It just says Invalid M Code still.

                                What do I do now?

                                    I can't figure out how to upgrade the firmware. I have the Arduino program, which I used to update the MKS board with Marlin. Pretty easy.

                                    What's the latest process for doing this for RepRap?

                                      Thanks, I just happened to see it at the same time I received your response.

                                      It's now homing X, Y, and Z.

                                      The next issue I have to work through is that it's not stopping on Z, and rams the bed. I double-checked the config update I was using, and used my finger to test the BLT, but it still rams.

                                      I'll go back through the thread, but you have an immediate fix then please let me know.

                                      Thanks for your help.

                                        Im using a BLTouch, a fairly new 'smart' version.

                                        It seems to be working correctly, but i've never cut the trace to change it from 5v to 3.3v.

                                        Since its hooked to the 5v output on the duet, whats correct?
                                        A) - Cut it to work at 3.3v
                                        B) - leave it at 5v
                                        C) - if its working don't f$*k with it regardless of settings,
                                        D) - Its gonna blow up, fry the duet, and burn down the house by running at 5v…..

                                          It's safest to cut the trace.

                                            Been trying to setup my BLTouch for a couple of days…
                                            I can't seem to find out how to do it properly... I do not get the flashing red, the probe retract, deploys a few times and remain red.

                                            I keep getting the Z-Probe field in red

                                            I tried wired has the image below. I also tried with the White wired in the Probe In instead of the E1.

                                            Since the field is red from connecting, I do not believe my issue to be from elsewhere then the Config.g

                                            I am using the 1.19.2 version. On a Duet 0.8.5

                                            I added the required code and .g files
