            so when the print starts it moves to z position 0?

            Well no when the print starts it will move the first layer height set by the slicer. 0.2 or whatever you have it set to.

              @Phaedrux yes it does move to the correct height for printing. I worked out why the machine was printing in reverse, embarrased to admit but i had the X and Y motors and end stops back to front ! lol
              I have the machine printing but for some reason it doesn't start the heater automatically, i have to heat the extruder then start a print to get t printing. Not sure what this error is :

              Error: Temperature reading fault on heater 0: sensor open circuit
              Resume state saved
              Printing paused at X0.0 Y0.0 Z0.0

              I will try my friend google and see what i can come up with, thanks again for all the help guys !

                @Phaedrux i am getting this error when trying to print:
                Warning: Tool 0 was not driven because its heater temperatures were not high enough or it has a heater fault

                I'm guessing that the extruder temp is set below the temp (260c) i want to print at. how do i change that if that's the case?
                Thanks in advance

                  What slicer are you using? Does it have the temp set for what you want?

                  You should add T0 to the end of your config.g so that the first tool is selected at startup. You should also add a T0 to your slicer start gcode just in case the tool gets deselected along the way.

                  Can you post a sample sliced gcode file so we can see what it's trying to do at the start of a print?

                    @Phaedrux Hi mate, i'm using Simplyfy3d so yeah i set my temps for my other machine all through S3D. Im not sure about the sliced gcode, but in the scripts tab the starting script is G28 ; home all axes

                    Ive also noticed my end script to lift the nozzle 50mm after print finishes doesn't work either?
                    M104 S0 ; turn off extruder
                    M140 S0 ; turn off bed
                    M84 ; disable motors
                    G91;
                    G1 Z50;
                    G92;

                      G92;

                      Well it disables the motors and then tries to move them so move the M84 to the end.

                        @Phaedrux thanks mate.
                        i tried adding the T0 line at the end of config and also in start script and still no go.
                        i get this error message.
                        Error: Temperature reading fault on heater 0: sensor open circuit

                          @Phaedrux could it be in the baude rate? my other printer runs rumba at 115200 baude rate the duet is different?

                            Are you printing over USB or are you uploading the gcode to the duet using the web interface?

                            Do the heaters work otherwise?

                            Have you PID tuned your heaters?

                              @Phaedrux uploading the file through web interface.
                              The heater can be set manually and work fine and i have PID tuned them. I upload a gcode file then click start print and i get this error message,
                              Warning: Tool 0 was not driven because its heater temperatures were not high enough or it has a heater fault

                              the printer will continue trying to print without heating the extruder so i just stop it. if i heat the hotend first then start a print it will print as i'm manually overriding the temp settings.
                              i think?

                                      @Phaedrux i assume you only need the start file?

                                        @Phaedrux this is the last code:
                                        ; layer end
                                        M104 S0 ; turn off extruder
                                        M140 S0 ; turn off bed
                                        G91;

                                          I think this is an issue with simplify 3d targeting the right heaters.

                                          Try this, go to stay folder and create a new file called start.g inside it put T0 and save it.
