      Good point, we need to measure them all again for 3.3.

      @FHesse what resistor do you have connected across the ADC board inputs (in parallel with the pyrometer output)? Those readings suggest that either the resistor is missing or its value is much too high.

      Is it safe to use spindle ground for a probe?

      @Alijambo73 in principle it should be OK to use a single wire provided that -VIN is tied to the AC ground to which the spindle is connected. However, in view of the possibility of things going wrong if ground become disconnected, my preference would be to use an opto isolator between the probe/spindle circuit and io6.in.

      @SDJ it's likely that the problem is loss of contact between the INT1 pad of the accelerometer chip and the PCB. If you have SMD hot air rework equipment and no-clean flux, you may be able to fix it.

      Pressure on a connector causing it to disconnect briefly perhaps?

      What was the exact fault? What did the temp graph show?

      @infiniteloop No, I didn’t touch the heatbreak as this is a Revo nozzle there is no PTFE tube inside just the nozzle tightened all the way in into the Roto extruder. The PTFE tube coming from the top barely gets inside the assembly without reaching the hobbed gears.

      @elmoret it is a nozzle from the early beta testing of the revo system when those were shipped without sock, so, for your point, it is genuine. There is no air path blocked aside from the front where the toolboard is supposed to be installed and the back for the mounting system, did you mean that?

      @dc42 Yeah, that's it.

      Now I can put a big red STOP button on the front of my machine: in the case that kittens, puppies, or tenured professors get stuck in the high-speed moving parts, the button cuts the power to the motors and they stop nearly instantly. Kittens everywhere are safer... perfect answer, thanks again!

      @FelixUCF which version 6HC board do you have?

      The 5V_ext supply on the IO_ connectors of the 6HC is derived from the main 5V supply through a diode. Older 1HC boards that do not support 48V VIN also have a PTC fuse in that circuit. The 5V_ext voltage on the IO_ connectors will be missing if either the diode or the fuse is open circuit.

      @lei2vaegh6 I suspect that your sensor a has high output leakage current, which is limiting the output voltage to 0.5V when it should be at least 3V. You can fix this in either of the following ways:

      Keep your current connections but add an external pullup resistor between the IO_IN pin and the 5V pin of the port you are using on the Duet. I suggest a resistor value of 1K to 2.2K.

      As you are using a 6XD board, you have 4 input ports (IO5 thru IO8) that provide alternative isolated inputs designed for connecting to 24V PLCs etc. See https://docs.duet3d.com/Duet3D_hardware/Duet_3_family/Duet_3_Mainboard_6XD_Hardware_Overview#opto-isolated-inputs. For example, you could connect the sensor output to IO5_ISO_NEG and connect IO5_ISO_POS to +24V. Then change your configuration to use port "!io5.in".

      @dc42 and @jay_s_uk , To address my issue, I don't have a desoldering station to handle the 3.3V regulator. Would you be able to help me? Can we return the product for troubleshooting?
      We can continue this discussion via private message.
