Printing Head acting suspiciously
-
Hi all,
After printing a few pieces, my printer started behaving suspiciously. First of all, there is about 10 degrees Celsius difference between what is set and the temperature measured at the extrusion head, Then the temperature of the extrusion head is not constant as it was before. A kind of shaking (or modulation) appears. I suspected a failure in the "Smart Effector" board and replaced it without any notable changes.
I have a 3D printer Delta Linear, Kossel clone with Duet2 WiFi electronics and RepRap firmware 3.4.4. Has anyone encountered such a problem? if so, how was it resolved?!
Can anyone help me?

Have you redone a PID tune? What command did you use?
It could also be noise on the thermistor wiring.
Can you post your full config.g?

@Phaedrux Yes. I did this a several times but I didn't notice any change in the heater behavior.
Used command was:
M303 H1 S260What bothers me the most is the big difference between the set temperature and the measured one.

@Phaedrux As it appeared, so it disappeared. This is very strange because the position of the printer has not been changed. I will try to change the wiring of the Smart Effector with shielded cables. Thanks.

Let us know if it reappears.
