Temperature problem.

Post by Bikerbuz » Mon Jan 14, 2019 9:40 pm

Hi there.

I have a really weird error (at least I think so) on my Mecreator 2, that I suspect is connected to a firmware issue.

I had a runaway temp on the nozzle a while back and melted a bunch of stuff. I replaced what was needed, re flashed it and tried printing.
Runaway temp once again.

The thing is that everything works fine up to 79c on the nozzle. As soon as I go above that it starts to get more and more inaccurate. For instance if I set it to 100c, it ends up at between 177c and 185c. It's not constantly ending up at exactly the same temp, it differs up to about 10c.
I replaced the thermistor again, but no improvement. Does anyone have any idea how to solve this?

*Edit*
It actually does trickle down to the correct temp eventually, but that means that if I for example want to print PLA at 200c, it simply gets way to hot before it eventually can settle at the correct temp
I guess this also happens when it tries to correct the temp mid print and that's what triggered the runaway temp the first time.
