Temperature error...

peirof

Hi,

since yesterday, often, 1 of 3 times, i have temperature errors, with this message:

 Error: Heating fault on heater 1, temperature excursion exceeded 15.0°C

and the printer pauses print job.

I have do calibration of nozzle thermistor, and save the results after,3 or 4 times.... but the error persists. With these results

 Auto tune heater 1 completed in 215 sec
 Use M307 H1 to see the result, or M500 to save the result in config-override.g
 Auto tune phase 3, peak temperature was 255.2
 Auto tune phase 2, heater off
 Auto tune phase 1, heater on
 M98 P"0:/macros/01 Temperatura/Calibrar temp Extrusor 230"
 Auto tuning heater 1 using target temperature 230.0°C and PWM 1.00 - do not leave printer unattended

Since all was ok, and now, with error, i have changed the conector of termopar, only this.

What can be?

There is a page on spurious heater faults in the Troubleshooting section of the wiki.
