      Yeah we are relying on the PI.

      We have no networking in this building yet. The pi is connecting to a wifi hotspot on my phone and I'm using that to talk to the printer.

      If I can use a network cable to go direct to my laptop I can probably make it work.

        Yes if you can route the cable that would work. You'd need to manually set an IP address for the Duet in config.g and then manually set an IP address on your laptop. Both IP addresses must be in the same subnet. Then you can connect to DWC via the Duet IP.

          Sounds good. Thanks. I'll get a long network cable next time I come down here. So if we need to go direct I'll be able to. Look forward to seeing what DC42 thinks. Thanks again for the help.

            Hi,

            Just out of curiosity what is the "raison d'etre" for a hang printer?

            Thanks.

              @fcwilt We are working with a group that is wanting to print building sized objects with a custom material, but the printer needs to be easy to transport. I know of no other printer that can do such a large print volume with so few materials for the printer itself. So we proposed a hangprinter This is the first phase proof of concept. If it works we'll be moving to a v4 hangprinter with a pellet extruder. This is why the mesh level needs to be working. We are currently trying to print on 4x8 sheets and will eventually be printing straight to the ground.

                Interesting.

                Hope it works out.

                  In case you're still at the printer to test.. Would you be able to try increasing the dive height? M558 H5 to H15? I just noticed that your M208 Z minima is -5mm which is the same as your dive height.

                    We'll probably be over later this week to work on it some more. I'll try setting the dive height larger than the z minima. And the other way around. It is interesting that probing one point manually currently works. Used to establish Z0 to before trying to create a mesh level. It only fails when trying to do the mesh. So it seems there is something odd there. It still does load the old mesh file from the last time I ran it before doing all the updates.

                      Can you post the heightmap.csv file from the previously saved G29 run?

                        Ok I tried:
                        M558 P0 H15 F120 T6000
                        M208 Z-5 S1

                        and:
                        M558 P0 H5 F120 T6000
                        M208 Z-15 S1

                        In both cases:
                        I ran G28 X0 Y0 Z0 E0 U0 then G30. The manual probing screen came up but the print head didn't move after setting height it moved up the dive height in M558. The running G29 this came up:

                          Here is the height map from the old config.

                            This would be preferable.

                            then G30. The manual probing screen came up but the print head didn't move after setting height it moved up the dive height in M558.

                            So when G30 is sent with M558 P0 set, there should be a prompt pop up to allow you to jog the Z axis up and down. Did that happen? Are you saying the movement buttons did not respond?

                              When sending the G30 command the the print head doesn't move and the ui for moving the axis comes up. The buttons work to move the print head. I use those buttons to set the height and hit ok. Then the head moves up to the dive height.

                              When sending G29 there is no motion only errors.

                              When it was working it would move to the location for each probe at z=H parameter in M558.

                              I wonder if the lack of motion at the start of G30 is an indication of what is causing the G29 to fail?

                                That's exactly how M558 P0 and manual probing works. You have to manually move the nozzle to touch the bed. So G30 sounds like it's working.

                                Once you've done that G30 and set the Z0 position are you able to jog the print head around manually?

                                With M558 P0 set, using G29 should indeed prompt you to jog down at each point.

                                And just to confirm, that's with this set?

                                  It moves around fine after g30. I can move it in a very large space and when I send it back to home it is right to the correct spot.

                                  The behavior was the same with:
                                  M558 P0 H15 F120 T6000
                                  M208 Z-5 S1
                                  and:
                                  M558 P0 H5 F120 T6000
                                  M208 Z-15 S1

                                  Tried both.

                                    Ok, so G30 is working, but G29 still complains that it can't reach all the points.

                                    At this point we don't know if it's a problem with the hang printer kinematic, the SBC DSF implementation, or a firmware problem, or some combination.

                                    Far as I know, you're the first one trying this.

                                    Things to test to narrow it down would be to try testing in standalone mode without the Pi as we discussed before. Though this would require running an ethernet cable up to the Duet.

                                      @phaedrux Was in the area and stopped by real quick. Tried running a G90 or G91 right after establishing the home. Tried this with dive bigger than minima and smaller and with the Z minima set to 0. All cases the G30 worked but the G29 still did not.

                                      Next step is to connect direct to duet with cable.

                                      The dive is currently set slightly larger than the Z minima. Here is the current config.

                                        Ok connected direct to duet. Pi is unplugged from it.

                                        Connected to it.
                                        Used G1 S2 commands to tighten individual axis to get to home location.

                                          Can you try with a different M557 command?

                                          Try M557 R200 S50

                                            That one still says it can't reach the points with same procedure as before. Just many more points.

                                            ...
                                            and so on.
