    pla does not normally need 250c to print

      i know, usually i print with 200-205°C

      you think is a thermistor problem or i need a new heater cartridge ?

      i have remake pid tuning ,still the same i can print pla only with min. 250°C

        pid tuning does not change the reported temperature.

        this is an indication of a wrong configuration.

        which thermistor are you using at the moment and what is your config line for it?

          I have this :

          M308 S1 P"e0temp" Y"thermistor" T100000 B3950 ; configure sensor 1 as thermistor on pin e0temp
          M950 H1 C"e0heat" T1 ; create nozzle heater output on e0heat and map it to sensor 1
          M143 H1 S300 ; set temperature limit for heater 1 to 300C
          M307 H1 B0 S1.00

          NTC-Thermistor 100 K 3950

          Thermistor Cartridge:
          Size: 1.25mmx2.0mm glass bead
          High accuracy: 1%
          Resistance value at 25°C=100K
          Wiring length: 1m / 39.3"
          Operating temperature range: -40 ° C + 300 ° C

            yeah that is why i dont like B3950 thermistors. the reported temperature can be way off.

                    its not uncommon for the 3950 to be off by 20C

                    did you change the beta and C value?

                        thats the thermistor: 104NT-4-R025H42G Semitec Thermistor 100K - NTC

                        i checked the datasheet and the B Value seems to be: 4267 ?

                        datasheet:

                          B and C change the algorithm to steinhart hart. its more accurate.

                          see the table

                              yes, but its still strange that you need 235 to print pla.

                              do you have a steel nozzle?

                                  ok steel nozzle a very bad for printing pla. the thermal transfer is very low.

                                  unless you are printing abrasive materials, a brass nozzle is a lot better.

                                  or if you want a much better nozzle, there are copper plated nozzles

                                          I have changed the nozzle and Calibrated all, all works fine now.
                                          I can print PLA with 200°C! Thanks

                                          i have another question i have Bed compensation in use: none is this normal ? i thin it should be mesh or not ?

                                          if you need config.g or slicer start.gcode or anything else tell me i will post it
