    I replaced the hot end assembly a couple weeks ago, but I didn’t make any changes to the way things were wired. I plugged it in to the same connectors as before.

        Yeah the exact same, it was the spare that came with the printer. I had messed up the original a little while ago when I changed out the nozzle from a V6 to a MK8 before I knew they were meant for different hot ends. The threading was the same and I thought that meant they were compatible… It had plastic leaking from around the heater block after that and after not using the printer for a bit, I did some research into where I went wrong and how to swap the parts out for the clean spare.

          Sorry, I’m a little confused.

          So you attempted to replace the nozzle or the hotend at first?

          and when you had a problem you replaced the hotend?

            Yeah that’s right, I bought the wrong nozzle and using it messed up my hotend. Replacing the whole hotend at that point was easier than trying to clean the plastic out from all the places it had leaked into.

              Alright, well then I wouldn’t rule out a very loose connection at the thermistor then.

              1. I’d probably test the thermistor’s reading with no steppers active. (unplug them if you have to)

              2. If signal is still noisy, pull the thermistor out and test. (possibly replace thermisitor)

              3. If it’s not noisy, move the hotend around with the steppers off and see if it gets noisy with motion. go back to 2

              4. If it’s still not noisy, it’s definitely EMF from the steppers, and you’ll need to replace the wire to the sensor. ideally with shielded wire and try not to run it along the same path as the stepper wires.
