      Should I make and post a video of what's happening? Would that help? Should I use 'Upload File' to do this? I;m assuming 'Upload Image' is for stills

        @Kayjay there’s a limit on the size of file you can upload, and videos are usually too big. Better to upload a video to somewhere like YouTube and post a link to it.

          My apologies for one massive error, the files I had installed on my SD were the ones as I explained earlier but I'm afraid those are the only ones I can find. I do have lots of copies -1, -2 etc etc but they appear to be the same so I've made a new set using the config tool and your figures which you noted down for me in your previous post, thank you so much, it was an enormous help. I'll now post the config.g I have on my SD and I would be very grateful if you would cast an eye over it and confirm it's ok. If it is I will then proceed with the next set of test that yourself and Phaedrux has listed for me. Again, I must thank you both for the time you have spent working with my problem, it's only because of that effort that hbas stopped me giving up and buying an Anet 8 Plus which seems good value for money and given that Thomas S has given it the thumbs up I was tempted but I prefer to work with my Bigbox and solve the problem. One main reason is the excellent Duet, there is nothing to touch it on the market ( it's just so darned complicated for novices like me 🙂 ) Thanks again Ian, I do appreciate everything you've done for me, you really are a star !

          Just a point, I know that there are a few commands that have to be either before or after others. Am I ok regarding this respect, is everything in the right order?

          Thanks again
          Keith

            @Kayjay looks mostly okay, and in the correct order. You have chosen the default thermistor settings, and a couple of other minor differences. Compare it to the config in your post earlier, here: https://forum.duet3d.com/post/171309

                  @Kayjay I’d say have a go with the Z movement tests, once you have your config.g sorted.

                  You can tell from the M122 response if the Z axis has stalled. Try moving Z, and if it doesn’t, send M122 and look at this line in the response:

                  Driver 2: standstill, SG min/max not available
                  

                  The bit after SG min/max will have numbers. If the max is 1023, the axis has tried to move, but stalled. It could be that the Z axis is binding, particularly as you have two motors on Z.

                    I sorted the config.g, the PT100 wasn't configured to use the daughterboard, just a slip of the mind .

                    This is the result of all the drivers from M122. I tried to move z then did the M122

                    Driver 0: standstill, SG min/max 0/234
                    Driver 1: standstill, SG min/max 0/295
                    Driver 2: standstill, SG min/max not available
                    Driver 3: standstill, SG min/max not available
                    Driver 4: standstill, SG min/max not available
                    

                    I assume this indicates that Z isn't trying to move. I can't get it to move using any Go or G1 command but it will move in homeall and homez.

                    I have made a video of Homeall.z which shows x and y homing, then x moving to 150 and y to 100 which is the centre of the bed. After that nothing happens, as though G30 is being ignored completely.

                    I'm busy trying to upload the video to youtube but at the moment I'm not able to, I do have an account but I have never uploaded anything to my account so it's a matter of another learning curve.

                    I am getting very close to giving in as nothing seems to works. I'd even send it to Josh at E3D but they no longer handle the Bigbox so I don't think they'll do a repair.To be honest I'd be happy to pay anyone who can make this darned thing work otherwise its the Anet A8 Plus. I am getting very frustrated even with the great help you've all given me. I feel there is an electronic problem rather than software. I'm just at a loss, you guys have been so amazing and helpful, your hints and tips have been amazing too but I just don't know what to do any more. For one I'm a novice so to speak, I don't understand half of the speak, I'd just be happy with a working printer that I can throw a sliced prog in and let it print me a nice result.

                      It sounds like the Z axis isn't stalling, so that's a good sign.\

                      The reason it won't move the Z axis with G0 or G1 is probably because it hasn't been homed yet, So unless you've sent a G92 Z10 to force the Z axis into a homed position, it won't move.

                      @Phaedrux said in Unable to home z axis:

                      https://wiki.e3d-online.com/BigBox_Version_Overview

                      I think this may be an issue of Z axis steps per mm being incorrect.

                      The marlin config for the Bigbox pro hydrid is 1600 steps per mm on Z. You've got it configured as 400.

                      #define DEFAULT_AXIS_STEPS_PER_UNIT {160,180,1600,417.5} // default steps per unit for Titan BigBox

                      So try changing your M92 Z400 to M92 Z1600 and try to homeall again.

                          Well, there is a small improvement, the bed now rises in the steps I have set in homeall, I have to keep homing but by hte time it reaches the top it crashes or rather would if I don't do an emergency stop. I've also tried holding my finger under the probe whilst it is homing , the LED lights but it doesn't stop, neither does it stop as it lights just before I hit emergency stop.

                          ; Uncomment the following lines to lift Z after probing

                          The Z-25 setting is temporary to enable a quicker bed rise so I don't have to hit homeall a hundred and umpteen times. Obviously I stop it crashing before it reaches it's limit

                            @Kayjay does the probe still give sensible numbers in DWC, ie 0 when not triggered, 500+ when triggered?

                            Can you post some pictures of the Duet and wiring?

                              @droftarts Yes, the probe numbers are still correct, 0 and 537. I've also managed to upload the video I made yesterday, I suppose it's out of date now as it shows that the bed doesn't rise after homeall but I thought I'd post it for completion. Here's the link, you may have to wait until 4pm for it to show, it's the earliest it would allow me to show it.

                              https://youtu.be/Xtr5PvMXFso

                              I'll also take some stills of the Duet wiring. Is it possible to post pics on here or should I put them somewhere else?

                                        Are the pictures above ok or would you like some more specific areas, particular clear shots of wires and plugs, not a prob if you require them.

                                          Well, there is a small improvement, the bed now rises in the steps I have set in homeall, I have to keep homing but by hte time it reaches the top it crashes or rather would if I don't do an emergency stop.

                                          Do you mean that G30 seems to be working now, or is it the G1 H2 Z-25 that is moving it up? That command will move it until it crashes, the probe won't stop it.

                                          Can you get a better photo of the probe wiring and the ir probe itself?

                                            @Phaedrux It's a bit of a mixture, if I comment out G30 the bed will rise whenever Homeall is activated, the head centres to the middle of the bed and the bed will rise the amount I have set in Homeall but if G30 is active ie not commented out then things return to as they were, all stops at the point G30 should home. I have also included two stills of the probe plug on the Duet and the plug on the probe itself.
