Good evening,
Just made an account as I have an issue I need fixing.
I’ve had an Ender 3 V2 for over 2 years, barely used, finally got it running again last week in terms of actual print time and running time it’s probably only run for a week or less.
I’m having “nozzle temp too low” issues, I’m using PLA+ by Esun which I run at 230°C, it ran fine until Wednesday (13th Nov 2024) evening this week, it had just completed a 2 hour print at 230°C no problem, I go to start a 45min print and not even 10% in I’m greeted by a thermal runaway message. After this it refuses to heat up over 185, I’ve sorted this but now it won’t go over 200.
I’ve read up about tightening the thermistor screw, but I can’t find a screwdriver that’ll give me enough torque to tighten it further, I’ve also read up on PID calibration(?) but I have no idea how to carry this out, and I don’t want to go through the trouble of replacing the hot end.
Any advice?
