When i start a print the nozzle tempetaure on the screen starts jumping from like 231 to 173 very quickly (btw the print is set to 210),
and eventually it will stop and beep very loudly and say that the nozzle tempetaure is too low.
any help please.
Have you tried to replace the thermistor, they break quite easily?
What is a good replacement thermistor? I’ve heard that some prefer a screw in type as well.
If the nozzle temperature is unstable, you can try adjusting the PID parameters. Use the M303 command to let the 3D printer perform an automatic PID tuning for the hotend, then use the M301 command to update the PID parameters, and save them to the EEPROM with the M500 command.
