issues with hotend temerature


New member
im having some issues with the hotend temperature stability like in the attached photo.
I have tried changing the thermistor but it made no differance.
it has been working about 500hrs before this.
What could be the issue?hotend-temp-issues2.png
When temp "jumps" suddenly, in other words faster than physics would allow, focus on wiring and/or crimps. Having said that, your jumps aren't that large compared with others I've seen.

Hope that helps you narrow it down!
I found the issue, one of the cables for the thermistor on the x carriage had started to break. Thanks for the assistance!
