        @veti i have tried it and still cant connect the bloody thing. so ive found the daugherboard connection point on the duet. that has 10 pins. i only have 4 wires (dual extruders' with two sets of black and red wires connected together) I just dont know where to put the bloody things. the images on the page you supplied are not very helpful and i cant crack the schematic. i think im just being stupid.

          @magdi Do you have a PT100 daughterboard?

                  Alright, sorry to say, but I don't think that will work. You'll need the daughterboard.

                    @phaedrux right is there not way just just bypass the pt100 and just connect the thermistor to the duet board?

                      Well if the sensor is a PT100 sensor, then no, it needs the daughterboard to interface with the duet. If you have a seperate regular thermistor, then yes, it could be connected to the thermistor input.

                          Here's how you connect a regular thermistor.

                              Is this an e3d thermistor?do you know the values to use for it?

                                  no you connected a pt100 and configure a ATC Semitec 104GT-2. that does not work.

                                  you need to get a ATC Semitec 104GT-2 or get the pt100 daugther board

                                      you just bought the wrong thermistor.
                                      that config is not for a pt100 sensor that you bought

                                      you got this.

                                          ok whilst im waiting for the thermistors ive hit a new problemo, the z axis motors are not working.

                                          currently i have two z axis motors and they're in parallel so two wires are connected to make one pin point (have tried singular connections too) .
                                          have had them in driver 0 but they're not working.
                                          have then re-pinned it to the E1 driver and managed to get the z to work so now i have all of the axis working yay. BUT driver 0 is still playing up. currently i have my other extruder there but its also not working. i keep getting a phase error as before for the Y driver. so the error, and no movement but every other driver works fine,

                                          have done everything as advised earlier in the thread so im no sure what else to do in relation to this driver.

                                            For the Z axis motors you may want to return the wiring to be straight through for each motor and then connect to the Za and Zb motor connectors, which are internally wired in serial.
