Hi Community,
Issue: I replaced my 4.2.2 motherboard for a 4.2.7 because I was having the motherboard heating issue.
Now I have a new problem, the extruder temperature is oscillating a lot, it doesn't stabilize.
It fluctuates a lot. A standard 200º print, can go anywhere from 180 to 220.
What I have done so far:
- Replaced thermistor for a brand new
- PID tuning multiple times, actually this will just make the problem worst as it will trigger the temperature runway error
- Tried different FW versions. Currently I'm using Jyers v1.3.5.b
Attached is the temperature during a normal print at 200º.
Any ideas? I'm about to rollback to 4.2.2...
Thank you
