Cooling Type

Stealthburner

An error occurred when printing the model today.



This is the klippy.log that I found.

What's the reason for this?
Thanks.




(It seems that this error occurs approximately every one and a half hours.)
I just checked the wires and the connectors.
Opened the hot end and gave it a clean.
But couldn't find anything wrong.


It seems that the klippy.log file couldn't be uploaded. There is a section of this issue.

Could be a broken wire in the loom. To test heat it up and move the gantry all around the perimeter to see if it cuts out.

Run a PID tune on the machine.

Sorry, my English is not very good.
What you mean is: There's a break somewhere in the wire at the hot end (the thermistor or heating block)?

Your test is to heat the hot end and then move the print head by hand to see if it will stop?



I executed the command: PID_CALIBRATE HEATER=extruder TARGET=20
No errors.

My trident hasn't been used for about half a year (it was fine before).
Today, when I opened it, it printed out a voron cube without any errors.
After creating a model of mine, this error occurred.

thanks
