I know the wire harness is a possibility for a flaky connection, but I don't think my #2 harness has enough miles on it to have an issue. Could be wrong.
Going to let the print keep going to see what happens.
Thermistor issue or ???

I'll vote for a going-bad thermistor, as I usually do. [grin]zemlin wrote:wire harness is a possibility for a flaky connection
On the five-minute-per-division timescale, the variations look entirely too slow, small, and regular to be caused by wire flexing.
Perhaps the thermistor pellet expands & contracts due to the hot end's slight temperature variations, causing similarly small resistance variations in the contact wire joints?
It'll take long enough for a catastrophic failure to let you order a new thermistor, anyway.

Thanks. I have a couple in the parts box - I'll swap it out when this print finishes.ednisley wrote:It'll take long enough for a catastrophic failure to let you order a new thermistor, anyway.
