          @phaedrux I'm running pid tune now on the bed. The bed with a IR gun is 10C higher then what the thermistor is showing

                    @phaedrux right now the thermistor in phase 3 reads 84 and the IR gun shows 96. Makes me wonder if the thermistor is bad

                      Where is the thermistor positioned to get the reading?

                      Are you measuring with the IR temp gun in the same location?

                        @phaedrux no, I actually testing it all 4 corners and in the middle where the thermistor is located

                          @phaedrux Almost 1 hour on phase 3. My other hypercube has already tuned using firm ware 1.21. now I'm wondering when I tell the extruder to heat to 220C its actually 220C. My first prints off them looked like they got pretty hot. I am using the e3d hemeria w/volcano direct drive. I also have their REVO

                            For the hotend you have a known thermistor and the correct values from E3D, so it should be as accurate as you can expect.

                            As for the bed, at 24v it takes a long time to heat up and it does many cycles, so it can take quite a while. Rather than tuning to 90c, try a more reachable temp like 60.

                              @phaedrux Hi, the problem was the thermistor in the bed. I swapped it out and now the temps are almost the same between the panel and the IR Gun. Now the gremlin has move to the extruder. I have a REVO Hermera direct drive and it keeps getting heater faults. I have ver 3.4.0 and ran M303 T0 S240 and it tunes fine. But I noticed the the temp rises above the print temperature I set and keeps going until there is a heater fault.

                                  @phaedrux Why is it saying Heater 0 when the fault happens on heater 1 the extruder? Not sure what is happening here!

                                    I think that is a bug in the displayed heater. Please update to 3.4.1 RC1

                                    https://github.com/Duet3D/RepRapFirmware/releases/tag/3.4.1rc1

                                    What did your tuned values result in?

                                    If the part cooling fan doesn't have a big impact on the heater, you can tune the hotend as a normal heater with M303 H1 S240 and see if it behaves better.
